Meeting Intelligence Platform

Overview

A meeting-intelligence platform that does the boring part of every call for you: a bot quietly joins the meeting, records it, figures out who said what, and turns it into a clean summary, action items, and a searchable transcript you can ask questions of later. Built to run multi-tenant from a single deployment, with billing and isolation taken seriously from day one.

Engineering decisions

• Tenancy enforced at the database — Postgres Row-Level Security with a per-request app.current_user_id set via a SQLAlchemy event hook, so the database itself rejects cross-tenant reads even if an application WHERE clause is ever forgotten. Defense in depth across 18 versioned migrations.
• A real capture pipeline, not an API wrapper — the bot joins ~90s early off calendar webhooks, captures audio through headless Chromium under a virtual display + null-sink, scrapes the participant roster to attach real names to diarized turns, then runs a silence gate → speaker-diarized STT → a two-pass Pydantic-AI analysis (high-recall extraction, then narrative minutes) → pgvector embeddings for per-meeting Q&A.
• Metered billing as a ledger — every paid LLM/STT/embedding call is recorded on an idempotent usage-events cost ledger, with per-user model routing and an admin cost dashboard.

Highlights

• Production ops — a RAM-bound concurrency cap that defers rather than drops recordings under load, full Terraform IaC (compute / storage / IAM / network), and one-shot deploys.
• Searchable memory — pgvector embeddings turn every meeting into a Q&A surface.
• Self-hosted + MIT — runs on your own infrastructure; no third-party recorder in the loop.
