Open-source meeting bots and real-time transcription β cloud or fully self-hosted.
A bot joins your Google Meet, Microsoft Teams, and Zoom calls and streams speaker-attributed transcripts in real time β through our API or one you host β then feeds sandboxed agents that build a Markdown knowledge base your team owns. Apache-2.0, air-gap-ready. (Jitsi: join + capture offline-proven, live validation pending β #883.)
vexa.ai runs Vexa 0.12 for meeting bots and transcription. Sandboxed knowledge agents are self-hosted only β self-host Vexa to run the full stack.
</div>Connect your agent Β· Get an API key Β· Talk to the founder
Why Vexa
Every meeting-AI tool you can buy sends your conversations to their cloud and rents you access back. Vexa inverts that: run the stack yourself, point it at your own models, own what your meetings become.
No one else has all three:
-
Vexa is in the meeting. A real bot joins Meet, Teams and Zoom β Jitsi offline-proven, live validation pending β and streams speaker-attributed transcripts live. That bot fleet is the genuinely hard part β every "chat with your docs" tool starts after a transcript exists. Vexa produces it.
-
Your knowledge is files you own. Meetings compile into Markdown in a git repo β portable, diffable, greppable. Knowledge as code.
-
Agents work it, safely. Sandboxed coding agents read and write that repo like developers β isolated ephemeral containers, no egress, thousands in parallel, on Docker or your Kubernetes.
Only here for the transcription API? It's a complete standalone product β send a bot, read the stream, ignore the agent lane entirely.
β‘ Quickstart
Just want a bot in a meeting? Use the hosted service β no install. Sign in at vexa.ai/signin, copy your key from your account page, and send a bot:
curl -X POST "https://api.cloud.vexa.ai/bots" \
-H "X-API-Key: $API_KEY" -H "Content-Type: application/json" \
-d '{"platform":"google_meet","native_meeting_id":"abc-defg-hij","bot_name":"Vexa"}'
New accounts get $2 of free bot credit, no card required β about 6 hours of bot time at $0.30/hr (pricing). More calls: Send a bot.
Or self-host the whole stack
That is also how you get the agent plane, which is not part of the hosted service. Self-host on one host, then explore it in the Terminal or drive it over the API. Linux (Ubuntu 24.04) is the production target; a Mac with Docker Desktop works fine for a local evaluation β everything runs in containers either way.
Prerequisites β make, Docker engine β₯ v26 (make all checks), and transcription: a free token at
vexa.ai/account, or self-host the (GPU) transcription unit for a fully
air-gapped setup. By default POST /bots requires STT and answers 503 when it is missing
(make all warns when the credentials block in .env is empty). Capture-only is an explicit opt-out:
{"transcribe_enabled": false} on the spawn (or set TRANSCRIBE_ENABLED=false for the deployment).
Build machine:
make allpulls the published, release-validated images β no build, so a modest box is fine.make lite(the single-container all-in-one image) is lighter still. Building from this checkout instead (make dev, for contributors) wants 8 vCPUs and 16 GB RAM.
git clone https://github.com/Vexa-ai/vexa.git && cd vexa
make all # full Docker Compose stack β seeds .env, pulls the images (bot included),
# prints your API key + URLs. Contributors: `make dev` builds from this checkout.
When make all finishes it prints your key and URLs:
Terminal UI : http://localhost:13000 # the web workbench
API gateway : http://localhost:18056 # the API
API key : vxa_β¦
Explore in the Terminal (the fast path)
The Terminal is the way to see what Vexa can do. Open http://localhost:13000 β you're
already signed in to a self-host account. From the
workbench you can, with no curl:
- Send a bot β paste a Meet / Zoom / Teams / Jitsi URL; a bot joins as a participant.
- Watch the transcript stream in live, speaker-attributed, draft-then-confirmed.
- Chat with your workspace β ask an agent that has every captured meeting as context, and watch it commit what you decide.
Or drive it over the API
export API_KEY=vxa_...
export API_BASE=http://localhost:18056
# WIN 1 β send a bot into a live call, then read the transcript as it streams
curl -X POST "$API_BASE/bots" \
-H "X-API-Key: $API_KEY" -H "Content-Type: application/json" \
-d '{"platform":"google_meet","native_meeting_id":"abc-defg-hij","bot_name":"Vexa"}'
curl -H "X-API-Key: $API_KEY" "$API_BASE/transcripts/google_meet/abc-defg-hij"
# WIN 2 β ask an agent that has your whole workspace as context (answer streams back as SSE)
curl -N -X POST "$API_BASE/agent/chat" \
-H "X-API-Key: $API_KEY" -H "Content-Type: application/json" \
-d '{"prompt":"What did we decide in my last meeting?"}'
platform is google_meet Β· teams Β· zoom Β· jitsi; native_meeting_id is the code from the join URL. The
agent reply streams as Server-Sent Events β message-delta frames carry the text, commit frames mark
anything it recorded into your workspace.
π§© How it works
One gateway, two domains β Meetings (capture) and Agents (work the knowledge) β both running on the same runtime: the engine that spawns every bot and every agent in its own sandboxed container.
<div align="center"> <img src="assets/architecture.svg" width="840" alt="One API gateway routes to two domains β Meetings and Agents β both running on one runtime that spawns each bot and agent in its own sandboxed container on Docker, Kubernetes, or Process."> </div>A bot and an agent are the same runtime.v1 workload β isolated, ephemeral, reaped on idle β so the
machinery already proven by thousands of meeting bots is exactly what runs your agents. Every arrow stays
inside your network.
βοΈ The agentic runtime
A CLI coding agent is just a process on Linux. The runtime makes that a multi-tenant, sandboxed execution layer safe to point at real business data β the same engine that already spawns Vexa's meeting bots in production.
- Isolated. Every dispatch gets its own container: no egress except brokered tools, and only its granted workspaces exist in its filesystem β enforced by the substrate, not by the agent. Agents never run in the control plane.
- Ephemeral. A container lives while it works and is reaped on idle; continuity is a session file in the workspace. Sub-second starts, thousands in parallel.
- Orchestration-agnostic. One
runtime.v1lifecycle, pluggable substrate β the same dispatch runs identically across:
| Backend (RUNTIME_BACKEND) | A workload is⦠| State |
|---|---|---|
| docker (default) | its own container via the Docker socket β brought up with make all | β
Shipped (open core) |
| process | a child process, no Docker socket required | β
Available |
| k8s | a bare Pod (kubectl run --restart=Never), scheduled across a cluster | β
Lifecycle + per-mount workspace isolation; Helm chart in deploy/helm |
Same control plane, same worker β only how the container is created changes. One laptop to a Kubernetes/OpenShift cluster, inside your walls.
π§ Agents & your workspace
Capture is the front door; agents make the knowledge compound. Every meeting compiles into
your workspace β a git repo of Markdown (an Open Knowledge Format
kg/ bundle) that agents (Claude Code, Codex, β¦) read and write like developers work a codebase.
This is Andrej Karpathy's LLM Wiki pattern, run as a team service. The idea: don't RAG over raw documents β where the model rediscovers everything from scratch on every question β have agents compile sources into structured, interlinked markdown entity pages (people, companies, projects, decisions) so knowledge compounds. Vexa builds that wiki for you from the richest source there is: your meetings. Each call is ingested into entity pages; agents keep them current between calls; every answer starts from what your team already knows β on your own servers.
Agents work any workspace; a meeting is just one trigger of four β chat, schedule (cron), event (e.g. incoming email), finished meeting. Meetings themselves are scheduled work: connect your calendar (ICS) and planned meetings appear with attendees β bots auto-join, agents prepare before the call and process after it.
- Multiplayer. Team-shared, attributed workspaces β not one person's private notes.
- Automated. The bot captures the call; the transcript compiles itself in.
- Safe by design. Agents are untrusted and enforce nothing themselves. You, in chat, write directly (git is the undo); untrusted input β an email, a web page β runs propose-only: the agent suggests, a human approves, trusted code applies. Irreversible effects are always gated.
Status (honest): capture, transcription, and speaker attribution are production; the agent dispatch core is built and proven live end-to-end. What's still landing is tracked in Status.
π₯οΈ The Terminal: AI-augmented meetings
0.12 ships a new Terminal UI built to put the backend's scale β thousands of bots and agents β to work on your actual week. It opens on your meetings: coming up, live now, to review.
-
An agent in your meeting, with your knowledge. Open a live call: the transcript streams speaker-attributed, and the agent has the live conversation and your workspace in context. Ask mid-call "what did we promise them last time?" β or research a person, company, or contract the moment it comes up, grounded in your wiki.
-
Knowledge built on meetings β and between them. Every planned meeting gets an agent that prepares the brief before (who's coming, history, open threads β it interviews you for what it can't know) and processes the transcript after. Arrive prepared, leave with the wiki updated.
-
Sharing. Invite colleagues into a workspace β same wiki, attributed. Share a meeting with its attendees β they get the real-time feed, not a recording link after the fact.
-
Collaborative, AI-augmented meetings. Prep a shared workspace together; during the call, humans edit the brief while agents stream the transcript in and work the knowledge β one room, human and AI participants on the same files.
π How-to recipes
Each is a complete path to one outcome over the Agent API. Full guides at docs.vexa.ai.
π¬ Chat with your workspace β ask an agent that has every meeting, email, and note as context; trusted chat can also record a decision (a git commit).
