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 — Jitsi offline-proven, live validation pending — and streams speaker-attributed transcripts live. That bot fleet is the genuinely hard part — 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 — portable, diffable, greppable. Knowledge as code.
Agents work it, safely. Sandboxed coding agents read and write that repo like developers — 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 — send a bot, read the stream, ignore the agent lane entirely.
Just want a bot in a meeting? Use the hosted service — 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 — about 6 hours of bot time at $0.30/hr (pricing). More calls: Send a bot.
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 — everything runs in containers either way.
Prerequisites — make, Docker engine ≥ 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 — 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 — 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_…
The Terminal is the way to see what Vexa can do. Open http://localhost:13000 — you're
already signed in to a self-host account. From the
workbench you can, with no curl:
…
platform is google_meet · teams · zoom · jitsi; native_meeting_id is the code from the join URL. The
agent reply streams as Server-Sent Events — message-delta frames carry the text, commit frames mark
anything it recorded into your workspace.
One gateway, two domains — Meetings (capture) and Agents (work the knowledge) — both running on the same runtime: the engine that spawns every bot and every agent in its own sandboxed container.
A bot and an agent are the same runtime.v1 workload — isolated, ephemeral, reaped on idle — so the
machinery already proven by thousands of meeting bots is exactly what runs your agents. Every arrow stays
inside your network.
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 — the same engine that already spawns Vexa's meeting bots in production.
runtime.v1 lifecycle, pluggable substrate — the same
dispatch runs identically across:Backend (RUNTIME_BACKEND) |
A workload is… | State |
|---|---|---|
docker (default) |
its own container via the Docker socket — brought up with make all |
✅ Shipped (open core) |
process |
a child process, no Docker socket required | ✅ Available |
k8s |
a bare Pod (kubectl run --restart=Never), scheduled across a cluster |
✅ Lifecycle + per-mount workspace isolation; Helm chart in deploy/helm |
Same control plane, same worker — only how the container is created changes. One laptop to a Kubernetes/OpenShift cluster, inside your walls.
Capture is the front door; agents make the knowledge compound. Every meeting compiles into
your workspace — a git repo of Markdown (an Open Knowledge Format
kg/ bundle) that agents (Claude Code, Codex, …) 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 — where the model rediscovers everything from scratch on every question — 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 — on your own servers.
Agents work any workspace; a meeting is just one trigger of four — 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 — bots auto-join, agents prepare before the call and process after it.
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.
0.12 ships a new Terminal UI built to put the backend's scale — thousands of bots and agents — 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?" — or research a person, company, or contract the moment it comes up, grounded in your wiki.
Knowledge built on meetings — and between them. Every planned meeting gets an agent that prepares the brief before (who's coming, history, open threads — 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 — same wiki, attributed. Share a meeting with its attendees — 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 — one room, human and AI participants on the same files.
Each is a complete path to one outcome over the Agent API. Full guides at docs.vexa.ai.
** Chat with your workspace** — ask an agent that has every meeting, email, and note as context; trusted chat can also record a decision (a git commit).
curl -N -X POST "$API_BASE/agent/chat" -H "X-API-Key: $API_KEY" -H "Content-Type: application/json" \
-d '{"prompt":"Brief me on the Acme account: every meeting, the open decisions, and the next step."}'
** Brief me every morning** — an unattended agent on a cron schedule that commits to your workspace.
curl -X POST "$API_BASE/agent/routines" -H "X-API-Key: $API_KEY" -H "Content-Type: application/json" \
-d '{"name":"Morning brief","cron":"0 8 * * 1-5",
"prompt":"Brief me from overnight activity — new meetings, decisions, follow-ups due. Write brief/today.md.",
"run_now":true}'
** Report after every meeting** — dispatch a one-shot agent when a call ends (or a routine that sweeps recent meetings).
curl -X POST "$API_BASE/agent/invocations" -H "X-API-Key: $API_KEY" -H "Content-Type: application/json" \
-d '{"runner":"claude-code","workspaces":[{"id":"u_jane","mode":"rw"}],"trigger":"scheduled",
"start":{"entrypoint":{"inline":"Write a report for the meeting that just ended: summary, decisions, action items with owners."}}}'
** Triage incoming email (safely)** — an event-triggered agent that gets the mailbox read-only and can only propose actions as cards; a human approves before anything is written or sent.
curl -X POST "$API_BASE/agent/events" -H "X-API-Key: $API_KEY" -H "Content-Type: application/json" \
-d '{"name":"email.received","source":{"uri":"mailbox://u_jane/INBOX/AB12CD"},
"plan":{"prompt":"Triage this email into tasks; propose a record for each action item and a draft reply."}}'
During the call — stream the live transcript with
GET /agent/meeting/streamand ask your agent about it in the chat. Vexa runs no model of its own during a meeting: there is one intelligence and it is your agent. See Status.
Two ways to run Vexa, one codebase:
1. Personal / dev — Docker on your Mac, Linux, or Windows machine.
Single container (make lite — the all-in-one Vexa Lite image) or the full Compose stack
(make all). **Reus
