969574bee4 feat(storage): wire the asset backend into the app (#1007) (#1089)
* fix(persistence): stop corrupting binary response bodies in the route adapter

The embedded persistence route bridges a Node `RequestListener` to the
Fetch API by hand. Its response object is cast with `as unknown as
ServerResponse`, so the compiler checks none of that surface, and two
parts of it were wrong in ways only a byte-carrying handler would hit.

`end` decoded any `Uint8Array` chunk with `Buffer.from(chunk).toString()`,
which is UTF-8. `ServerResponse.end` accepts a `Uint8Array`, and those
bytes are not necessarily valid UTF-8, so every unpaired byte became
U+FFFD -- silent corruption with no error anywhere. The adapter now
buffers chunks as bytes and builds the response from them.

`write` was absent entirely, making any chunked handler a runtime
TypeError rather than a compile error. It is part of the surface this
object claims to implement, so it is now implemented.

Neither reaches a caller today: the document and runtime handlers only
ever end with JSON strings, which took the string branch. Both are traps
laid for the first handler that carries bytes.

Both cases are pinned by tests that fail before this change -- the
binary one on a byte comparison, the chunked one with a 500 from the
TypeError. The existing adapter round-trip test, whose comment already
called this the most bug-prone code in the route, covered only the
string path.

* feat(storage): wire the asset backend into the app (#1007)

The server asset registry shipped with #1007 but was reachable from
nothing: the persistence route never passed an `assetStore`, and no file
under `app/`, `lib/` or `components/` imported the asset server or client
modules. This connects it, additively -- no DSL change, no version bump,
and no behavioural change when server persistence is off.

The route now builds a `PgAssetStore` on the same pool and transaction as
the document store, with `PgAssetByteStore` by default and
`S3AssetByteStore` when `ASSET_S3_BUCKET` opts a deployment into it. The
AWS SDK stays an optional peer, reached only through a dynamic import on
that branch. The offline collector is deliberately not scheduled here,
and the route says so where a reader would look for it, because leaving
it unscheduled grows storage without bound and scheduling it is the
deployment's decision.

On the browser side the asset pool gains a single-shot configuration seam
modelled on the document store's, so that with server persistence enabled
the pool is an `HttpAssetStore` carrying the same auth headers as the
other stores.

Three browser-specific mechanisms needed decisions rather than
translation:

`clearAssetPool` deletes an IndexedDB database today. In server mode
there is nothing local to delete, and a "clear cache" action must not
remove server-side assets -- that would destroy user data from a button
promising to free space. It now revokes local object URLs and closes the
client, and deletes nothing remote.

The cross-tab replacement broadcast is unchanged. Its job is to make
another tab drop a warm object URL when the bytes behind an id change,
and that need is identical in server mode.

The exclusivity proof that decides whether an in-place `replace` is safe
reasons over this browser only: local documents, unflushed state, and a
cross-tab presence probe. In server mode those cover a strict subset of
the holders, since another device can reference the same id and no probe
can see it -- and asking the server who else references an id would be an
existence oracle over other principals. The proof therefore returns not
exclusive unconditionally in server mode, and regeneration takes the
existing fork path. That is the fail-closed direction and a graceful
degradation rather than a break.

The development authenticator had to grow the asset principal's required
`key`; without it every asset request would have been correctly denied.
It derives from the same learner partition, and a principal without one
still gets no asset access. The route now states plainly that this key
comes from a client-supplied header, so the cross-principal isolation the
asset contract describes is not in force under this authenticator -- that
warning previously lived only in the auth module's own header, where
nobody mounting the route would see it.

* fix(storage): close three defects in the asset app wiring (#1007)

**The S3 branch could not load, and isolated nothing.** The route
dynamically imported the storage package's S3 byte store, but that module
statically imported the AWS SDK, so merely resolving it pulled the SDK
into resolution and bundling. The route then separately performed an
ignored native import of the SDK from the app's own scope, which fails
with ERR_MODULE_NOT_FOUND because the SDK lives under the storage
workspace package -- so a deployment that set the bucket got a broken
store rather than an S3 one. There is now one lazy loader in one
resolution scope, the storage module no longer imports the SDK at module
load, and the bucket is validated at initialization rather than treated
as valid because it is non-empty. A test mocks the SDK to throw on
resolution and asserts that importing the byte-store module never
resolves it.

**A cross-tab replacement could leave a mounted lease stale.** The
broadcast handler re-resolves, and `HttpAssetStore.resolve` coalesces
concurrent calls for one id onto a single in-flight request -- correct on
its own, and required by the contract. Together they meant a resolve
triggered by the broadcast could merge into a GET that started before the
peer's replacement, return the old revision, and leave the consumer on
the old URL with nothing to dislodge it. The client gains an invalidation
that retires its cached snapshot and advances the per-id generation
without revoking any URL already issued; `release` would have been wrong
here, since the contract keeps an issued URL valid until its holder
releases it. Removing the invalidation call fails the new race test.

**Clearing a server-backed pool left the closed client installed.** In
server mode `clearAssetPool` closed the client and returned before
clearing the module singleton, so every later `getAssetPool()` handed
back a closed store until a page reload happened to intervene. Only the
IndexedDB deletion is skipped in server mode now; the singleton is always
cleared so the next call rebuilds through the configured factory.

Also adds the tests whose absence let these through: a route round-trip
carrying invalid UTF-8, the SDK-resolution assertion above, the broadcast
race, and reopening the pool after a clear. The earlier tests were not
wrong so much as aimed past the defect -- the route test used JSON text,
and the S3 test injected a loader rather than exercising the imports.

* chore(storage): bump package version to 0.3.0

* fix(persistence): make the route adapter faithful where it carries bytes

The embedded persistence route bridges a Node `RequestListener` to the
Fetch API by hand, and its response object is cast
`as unknown as ServerResponse`, so the compiler checks none of that
surface. Five divergences are closed here; the first two are the ones
that corrupt data, the last three were raised in review.

**`end` decoded bytes as text.** It ran `Buffer.from(chunk).toString()`
on a `Uint8Array` chunk, which is UTF-8, so every byte outside that
encoding became U+FFFD -- silent corruption with no error anywhere. The
adapter now buffers chunks as bytes.

**`write` was absent**, making any chunked handler a runtime `TypeError`
rather than a compile error.

**`write` callbacks ran inline.** Node invokes them after the chunk is
handed off. A handler that writes its next chunk from each callback
therefore recursed synchronously and could overflow the stack, and a
throwing callback threw in the wrong execution phase. They are now
deferred.

**The encoding argument was ignored.** `write(s, 'latin1')` emitted
`0xc3 0xa9` where Node emits `0xe9`, corrupting the body and potentially
invalidating a `Content-Length` the handler had set. Both `write` and
`end` now parse their full overload set and pass the encoding through.
Node's own behaviour for an invalid encoding was established by probing
`ServerResponse` on Node 22 rather than assumed: it throws
`ERR_UNKNOWN_ENCODING` synchronously, so the adapter validates with
`Buffer.isEncoding` and lets `Buffer.from` raise the native error.

**Bodyless statuses were not suppressed.** Node discards writes after
`writeHead(204)` or `writeHead(304)`; this passed the buffered bytes to
the Fetch `Response` constructor, which throws for those statuses, so the
request became a 500 instead of the intended 204 or 304. Buffered data is
now discarded for 204, 205 and 304, and for `HEAD`.

None of the five reaches a caller today -- the document and runtime
handlers only ever end with JSON strings. They are traps laid for the
first handler that carries bytes, which is why they surfaced while
wiring the asset server backend, whose byte routes hit the first two
immediately.

Each is pinned by a test that fails when its fix is reverted.

* fix(storage): keep { client, bucket } working for the S3 byte store

`S3AssetByteStoreOptions.commands` was required and the store's methods
called it directly, so the published `./asset/s3-bytes` export stopped
accepting the `{ client, bucket }` construction it had always taken.
Anyone not going through `loadS3AssetByteStore` either failed to compile
or hit an undefined command factory at runtime.

Make `commands` optional. Omitted, the store resolves the AWS SDK's own
command constructors through a dynamic import on its first `write` /
`read` / `delete` and caches them, so `{ client, bucket }` works again.
Importing the module and constructing a store still never reach the
optional peer dependency: a deployment that does not select S3 never
resolves it. When the SDK cannot be resolved the call rejects naming
`@aws-sdk/client-s3` rather than crashing on an undefined property, and
the resolution is left uncached so installing the dependency fixes an
already-constructed store.

The lazily bound store is run against the byte-store contract, and the
new isolation tests pin both that construction does not resolve the SDK
and that an unresolvable SDK is reported by name.

With the break gone this branch's change to the package is additive, so
the version becomes a patch above main (0.2.4 -> 0.2.5) rather than the
minor it was carrying.

* feat(persistence): run the asset collector in the shipped deployment

`PgAssetStore.remove`, and a `replace` that changes content, only stamp
`asset_blobs.unreferenced_at`. `AssetCollector.collect` is the only path
that deletes anything, and the persistence route deliberately did not
schedule it, on the grounds that scheduling is the deployment's decision.

The deployment this repository ships is docker-compose.yml: the app and
PostgreSQL, and nothing else that could make that decision. "The
deployment decides" therefore meant "it never runs", and ordinary asset
churn retained PostgreSQL bytes or S3 objects forever.

Schedule it from instrumentation.ts, which Next runs once per server
process — a route module can be instantiated more than once and has no
shutdown hook, so a schedule started from one is really started per
instantiation. Next 15 and later pick the file up with no config, so
next.config.ts is unchanged.

Collection is on by default with a 15-minute interval and the package's
one-hour grace period, so the Compose stack is correct with no operator
action. ASSET_COLLECTION_INTERVAL_MS, ASSET_COLLECTION_GRACE_MS, and
ASSET_COLLECTION_ENABLED change or disable it, each documented where it
is read. Without DATABASE_URL nothing is scheduled at all, and a failed
pass is logged and retried on the next tick rather than ending the
schedule or the process.

Several instances may collect concurrently: each candidate blob row is
re-checked and locked FOR UPDATE inside its own transaction, so
collectors serialize on the row rather than racing. The comment says so,
so nobody adds a distributed lock that is not needed.

The byte-store selection moves to lib/persistence/asset-byte-store so the
collector reclaims through the same layer the request path wrote through.
A collector on the PostgreSQL byte store while the route wrote to S3
would drop the blob row and orphan the object permanently.

* feat(storage): bound each collector pass and report whether it filled

An unbounded collect() is sized by however long a deployment ran before
collection was scheduled: one statement selecting every eligible blob,
then a transaction and a byte-layer delete each, in a loop nothing
interrupts. The first pass over the Compose deployment that grew a
backlog before collection was scheduled is exactly that pass.

A pass now takes at most batchSize blobs (default one thousand) and
returns. Ordinary churn between two scheduled passes is far below the
cap, so a healthy deployment behaves as it did when a pass was
unbounded; a capped pass costs the remainder one scheduling interval,
which is what the interval is for.

collect() still answers with the count, and the count alone cannot tell
an empty backlog from a full batch -- a re-referenced or concurrently
taken candidate is skipped, so even a full batch can collect less than
batchSize. collectPass() returns the count together with capped, which
is exactly "this batch was full, run again"; a caller draining a
backlog loops while it is true.

Candidates are taken oldest-unreferenced first, with the content hash
as tiebreaker within one timestamp. Ordering by the hash alone would
starve: digests are uniformly distributed, so a high-sorting blob
waits behind every lower digest stamped after it, and under steady
arrivals those keep coming. The tests pin the ordering against a
planner that happens to answer the right rows without an ORDER BY.

* fix(persistence): keep asset backend faults off the shared handler

Two review findings on the app wiring.

A concrete asset pool instance is single-lifecycle, but
resolveConfiguredAssetPoolStore handed the same object out again after
clearAssetPool() had closed it, reinstalling a dead store as the live
pool. The second handout now refuses loudly and points at the factory
form, which rebuilds on every resolution.

createPersistenceHandler eagerly awaited the asset byte store, so an
invalid ASSET_S3_BUCKET or an unresolvable AWS SDK rejected the shared
persistence handler and took document and runtime traffic down with an
optional backend. Byte-store construction is now deferred to the first
asset byte operation, and a failed construction is not cached, so the
next asset request retries -- the route's own no-poisoned-singleton
rule.

Vercel Deployment

Deploy with Vercel

Or manually:

  1. Fork this repository
  2. Import into Vercel
  3. Set environment variables (at minimum one LLM API key)
  4. Deploy

Docker Deployment

cp .env.example .env.local
# Edit .env.local with your API keys, then:
docker compose up --build

Server-backed persistence (PostgreSQL)

The server-persistence profile runs exactly two containers: the OpenMAIC app and PostgreSQL. The persistence HTTP server is embedded in the app at /api/persistence; there is no standalone persistence service.

cp .env.example .env.local
printf '\nDATABASE_URL=postgres://openmaic:openmaic-dev@postgres:5432/openmaic\nPERSISTENCE_DEV_TOKEN=openmaic-local-dev\n' >> .env.local
NEXT_PUBLIC_PERSISTENCE=1 NEXT_PUBLIC_PERSISTENCE_TOKEN=openmaic-local-dev docker compose --profile server-persistence up --build

Add your provider API keys to .env.local as usual. Runtime sessions and course documents become server-backed; device-scoped KV data (including the anonymous device learner key and playback position) remains in the browser. Existing browser course data is copied into the configured server store lazily, one course at a time when it is first accessed, using the same verified migration path as browser persistence.

NEXT_PUBLIC_PERSISTENCE is a build-time switch compiled into the browser bundle. A build with it enabled must be deployed with a working runtime DATABASE_URL and PERSISTENCE_DEV_TOKEN, while NEXT_PUBLIC_PERSISTENCE_TOKEN must match that server token at build time. Otherwise the browser selects HTTP persistence but the embedded endpoint returns configuration/authentication/initialization errors; the home page shows a persistence-unavailable toast and keeps the prior course list instead of misleadingly displaying an empty library.

PERSISTENCE_DEV_TOKEN and NEXT_PUBLIC_PERSISTENCE_TOKEN are not a secret in any meaningful sense: the NEXT_PUBLIC_ token is compiled into the public JavaScript bundle, fully visible to every visitor, and therefore provides no confidentiality and no user isolation whatsoever — anyone who can load the page can extract it and read or write every learner partition and all documents by choosing an x-learner-key. Its only purpose is to keep unrelated network scanners out of an endpoint on a trusted network. This is suitable only for localhost or trusted-network, single-user deployments. Before production, replace lib/persistence/server-auth.ts with real session verification that derives the learner partition from server-controlled identity, and change the document/merge/admin authorization policies as appropriate.

PERSISTENCE_POSTGRES_PASSWORD initializes the PostgreSQL role only when the data directory is empty; changing it later does not rotate an existing openmaic-postgres volume. For a disposable local database, run docker compose --profile server-persistence down -v, set the new password and matching DATABASE_URL, then start the profile again. To preserve data, connect as an administrator and run ALTER ROLE openmaic WITH PASSWORD 'new-password';, then update DATABASE_URL.

Compose cannot attach depends_on to openmaic only when this optional profile is active without also affecting the default deployment. Startup therefore relies on the embedded route's retry-on-next-request behavior while PostgreSQL becomes healthy.

Deleting or replacing an asset only drops its registry entry; the bytes behind it are reclaimed afterwards by an offline collector. This deployment runs that collector by default, so nothing has to be configured for asset storage to stop growing. A pass runs every ASSET_COLLECTION_INTERVAL_MS (default 15 minutes) over bytes that have been unreferenced for longer than ASSET_COLLECTION_GRACE_MS (default 1 hour); the grace period is the retention window a user's deleted bytes actually get, so raise it deliberately. Set ASSET_COLLECTION_ENABLED=0 to switch collection off in a process. A horizontally scaled deployment may leave it on in every instance — each blob row is locked and re-checked before its bytes go, so concurrent collectors serialize rather than race — or disable it everywhere and run its own.

The embedded endpoint implements the package's RuntimeStore HTTP contract and DocumentStore HTTP contract. Leave NEXT_PUBLIC_PERSISTENCE unset to retain the existing browser-only behavior.

Optional: MP4 Video Export (Render Service)

The "Export Video" menu builds a self-contained Hyperframes project entirely in the browser. Turning that into an MP4 needs Chromium + FFmpeg on Node 22, so it runs in an isolated render-service container rather than the app.

It's opt-in. Start it with the video-export compose profile:

docker compose --profile video-export up --build

The app auto-detects the service via RENDER_SERVICE_URL (preset in docker-compose.yml) and enables one-click MP4 rendering. Without the profile — or when RENDER_SERVICE_URL is unset — export degrades to downloading the project ZIP for local CLI rendering. See render-service/README.md for standalone setup and tuning (RENDER_MAX_CONCURRENCY, etc.).

Optional: MinerU (Advanced Document Parsing)

MinerU provides enhanced parsing for complex tables, formulas, and OCR. You can use the MinerU official API or self-host your own instance.

Set PDF_MINERU_BASE_URL (and PDF_MINERU_API_KEY if needed) in .env.local.

Optional: VoxCPM2 (Self-Hosted TTS with Voice Cloning)

VoxCPM2 is an open-source TTS model from OpenBMB with voice cloning. OpenMAIC ships an adapter; run VoxCPM on your own hardware and OpenMAIC will talk to it.

1. Run a VoxCPM backend. Three deployment styles, all behind the same OpenMAIC adapter. You toggle which one in Settings.

Backend Endpoint When to use
vLLM-Omni /v1/audio/speech OpenAI-compatible speech endpoint, ideal for GPU servers
Python API /tts/upload Official VoxCPM Python runtime via FastAPI

See the VoxCPM repo for backend setup.

2. Point OpenMAIC at it. Open Settings → Text-to-Speech → VoxCPM2, pick the backend, and paste your Base URL. The Request URL preview confirms OpenMAIC will hit the right endpoint.

VoxCPM2 connection settings: backend selector, Base URL, model

Or pre-configure it via env var (no API key required):

TTS_VOXCPM_BASE_URL=http://localhost:8000/v1

3. Manage voices. Three voice modes, all under Settings → Text-to-Speech → VoxCPM2 → VoxCPM Voices.

VoxCPM2 VoxCPM Voices section with Auto, Prompt and Clone modes
  • Auto Voice (default): OpenMAIC generates a voice prompt from each agent's persona at synthesis time. No setup required.
  • Prompt voice: describe the voice in natural language, e.g. "warm female teacher voice, calm and encouraging, mid-pitch".
  • Clone voice: upload a short reference audio clip or record one in the browser. The clip is stored in IndexedDB and sent to your VoxCPM backend on each synthesis.

✨ Features

Deep Interactive Mode (New!)

Passive listening? ❌ Hands-on exploration! ✅

As Einstein said: "Play is the highest form of research."

While Standard Mode focuses on quickly generating classroom content, Deep Interactive Mode goes further — creating interactive, explorable, hands-on learning experiences. Students don't just watch knowledge; they adjust experiments, observe simulations, and actively explore how things work.

Five Types of Interactive UI

🌐 3D Visualization

Three-dimensional visual representations that make abstract structures more intuitive.

⚙️ Simulation

Process simulations and experimental environments for observing dynamic changes and outcomes.

🎮 Game

Knowledge-based mini-games that reinforce understanding and memory through interactive challenges.

🧭 Mind Map

Structured knowledge organization to help learners build an overall conceptual framework.

💻 Online Programming

In-browser coding and instant execution for learning by writing, testing, and iterating.

AI Teacher Guidance

The AI teacher can actively operate the UI to guide students — highlighting key areas, setting conditions, providing hints, and directing attention at the right moments.

Available on Any Device

All generated interactive UI is fully responsive — desktop, tablet, or mobile.

Desktop

Mobile

iPad

Lesson Generation

Describe what you want to learn or attach reference materials. OpenMAIC's two-stage pipeline handles the rest:

Stage What Happens
Outline AI analyzes your input and generates a structured lesson outline
Scenes Each outline item becomes a rich scene — slides, quizzes, interactive modules, or PBL activities

Classroom Components

🎓 Slides

AI teachers deliver lectures with voice narration, spotlight effects, and laser pointer animations — just like a real classroom.

🧪 Quiz

Interactive quizzes (single / multiple choice, short answer) with real-time AI grading and feedback.

🔬 Interactive Simulation

HTML-based interactive experiments for visual, hands-on learning — physics simulators, flowcharts, and more.

🏗️ Project-Based Learning (PBL)

Choose a role and collaborate with AI agents on structured projects with milestones and deliverables.

Multi-Agent Interaction

  • Classroom Discussion — Agents proactively initiate discussions; you can jump in anytime or get called on
  • Roundtable Debate — Multiple agents with different personas discuss a topic, with whiteboard illustrations
  • Q&A Mode — Ask questions freely; the AI teacher responds with slides, diagrams, or whiteboard drawings
  • Whiteboard — AI agents draw on a shared whiteboard in real time — solving equations step by step, sketching flowcharts, or illustrating concepts visually.

OpenClaw Integration

OpenMAIC integrates with OpenClaw — a personal AI assistant that connects to messaging platforms you already use (Feishu, Slack, Discord, Telegram, WhatsApp, etc.). With this integration, you can generate and view interactive classrooms directly from your chat app without ever touching a terminal.

Just tell your OpenClaw assistant what you want to learn — it handles everything else:

  • Hosted mode — Grab an access code from open.maic.chat, save it in your config, and generate classrooms instantly — no local setup required
  • Self-hosted mode — Clone, install dependencies, configure API keys, and start the server — the skill guides you through each step
  • Track progress — Poll the async generation job and send you the link when ready

Every step asks for your confirmation first. No black-box automation.

Available on ClawHub — Install with one command:

clawhub install openmaic

Or copy manually:

mkdir -p ~/.openclaw/skills
cp -R /path/to/OpenMAIC/skills/openmaic ~/.openclaw/skills/openmaic
Configuration & details
Phase What the skill does
Clone Detect an existing checkout or ask before cloning/installing
Startup Choose between pnpm dev, pnpm build && pnpm start, or Docker
Provider Keys Recommend a provider path; you edit .env.local yourself
Generation Submit an async generation job and poll until it completes

Optional config in ~/.openclaw/openclaw.json:

{
  "skills": {
    "entries": {
      "openmaic": {
        "config": {
          // Hosted mode: paste your access code from open.maic.chat
          "accessCode": "sk-xxx",
          // Self-hosted mode: local repo path and URL
          "repoDir": "/path/to/OpenMAIC",
          "url": "http://localhost:3000"
        }
      }
    }
  }
}

Export

Format Description
PowerPoint (.pptx) Fully editable slides with images, charts, and LaTeX formulas
Interactive HTML Self-contained web pages with interactive simulations
Classroom ZIP Full classroom export (course structure + media) for backup or sharing

Offline / intranet classrooms: When you export a classroom (.maic.zip) or a Resource Pack, OpenMAIC inlines the external assets referenced by interactive scenes (KaTeX, Three.js incl. three/addons, Tailwind CDN, Google Fonts, images) into the exported HTML as data: URIs. The exported course then plays fully offline after import into an air-gapped/intranet instance — no public CDN is contacted at playback time. Assets that can't be fetched at export time (e.g. CORS-restricted image hosts) are reported and left as URLs. Classrooms exported before this feature still reference CDNs and must be re-exported to gain offline support.

And More

  • Text-to-Speech — Multiple voice providers with customizable voices
  • Speech Recognition — Talk to your AI teacher using your microphone
  • Web Search — Agents search the web for up-to-date information during class
  • i18n — Interface supports 7 languages: Chinese (Simplified & Traditional), English, Japanese, Russian, Arabic, and Portuguese (Brazil)
  • Dark Mode — Easy on the eyes for late-night study sessions
