Know why your company decided anything.
Company Brain captures every decision — its evidence, the people, the outcome — and answers from your team's own knowledge, with citations or an honest “I don't know.”

“pgvector lets us run similarity search directly in Postgres…”
[2] Eng sync · 2026-01-09
“Standardize on magic-link + Google; drop password auth.”
The “why” keeps evaporating.
Decisions get made in threads, docs, and meetings — then scatter. The reasoning and evidence are the first things lost.
- New hires re-litigate settled debates.
- Nobody can find the evidence behind a call.
- “Why did we do it this way?” goes unanswered.
Decisions, captured with their evidence.
The AI drafts a decision record from your own content — title, date, participants, supporting evidence, and the expected outcome. You review and confirm; nothing is saved without you. Then come back and record what actually happened.
- AI-drafted, human-confirmed — never auto-created
- Evidence kept even if the source later changes
- A timeline of why your org is the way it is

Why did we choose Postgres?
We chose PostgreSQL because pgvector lets us store embeddings and run similarity search directly in Postgres, avoiding a separate vector database.[1]
What is our 2027 hiring plan?
I don't have enough information to answer that from your organization's content.
Answers you can trust — or an honest “I don't know.”
Ask in plain English. Every answer is grounded in your organization's content with inline citations. When nothing relevant exists, it abstains instead of guessing — so you never get a confident, made-up answer about your own company. Turn any answer into a confirmed decision in one click.
Bring your knowledge in seconds.
Paste text or upload a file with its source and date. We chunk it, embed it locally, and store the vectors in your Postgres — ready to search and cite.

Everything in Company Brain
A focused toolkit for organizational memory — not another chat window.
Decision Ledger
The AI drafts a decision from your content — title, date, participants, evidence, expected outcome. You confirm; it lives on a timeline with what happened after.
Cited answers
Ask in plain English. Every answer is grounded in your org's content with inline citations.
Abstains, never bluffs
No relevant source? It says “I don’t have enough information” instead of inventing facts.
Bring your knowledge
Paste text or upload .txt/.md with a source and date — auto-chunked and embedded for search.
Teams & roles
Multi-tenant orgs with owner / admin / member roles and email invitations.
Permission-aware
Every query is scoped to your organization. You never see another org's data.
Simple sign-in
Email magic link or Google. No passwords to manage.
Your data, your providers
Runs on your Postgres; the AI and embedding providers are swappable (local or hosted).
You only ever see what you're allowed to.
Permission-aware retrieval filters every search by your membership before an answer is generated — a user can never receive a citation from content they can't access. Each organization's data is isolated, stored in your own Postgres, and the AI providers are yours to choose.
- Multi-tenant isolation — every query scoped to your org
- Per-chunk access scope checked before retrieval
- Secrets in env vars, validated at startup — never in the repo
Retrievable & citable
Never returned to you
How it works
Add your knowledge
Paste or upload notes, docs, and threads — tagged with their source and date. We chunk and embed them locally.
Ask & capture
Search with cited answers, then turn any answer into a confirmed decision in one click.
Remember
Decisions land on a timeline. Come back later and record what actually happened.
