What we know.
Why it matters.
- 01 / Sources
- Product briefs, project documents and reference material.
- 02 / Decisions
- The choice, the reasoning and what it changes.
- 03 / Methods
- Standard operating procedures and reusable AI skills.
Start with one active project. Add the current brief, agreed decisions and a process worth repeating.
What it is
A wiki waits to be read. A company brain gets used.
Most company knowledge bases are written for people to browse: pages in a wiki, folders in a shared drive, answers buried in old threads. The knowledge is there, but nobody finds it at the moment they need it.
A company brain is a knowledge base your AI assistants work from directly. When someone asks ChatGPT or Claude to draft a proposal, onboard a new hire or plan a launch, the assistant searches the team's documents, decisions and procedures first, and saves what it learns back for the next person.
Brainlet gives every team that shared brain. It searches by keyword and by meaning, so a question about “pricing decisions” finds the note titled “Why we dropped the annual plan”. It works across assistants, so knowledge saved from Claude Code is there when a teammate opens Codex.
What goes in
Everything your team knows, in one searchable place.
Decisions & reasoning
What the team chose, why, and what it changes. That's what stops the same debate from happening twice.
Procedures & skills
Standard operating procedures saved as reusable AI skills, so a process runs the same way every time.
Facts & preferences
Brand voice, customer names, house style and all the small facts people keep re-explaining to AI.
Connected sources
Google Drive, Google Docs, Gmail and GitHub, read where they live and filtered by each person's own permissions.
Team context
Who is working on what, and which project a document belongs to, so answers come from the right place.
Works with
- ChatGPT
- Claude
- Claude Code
- Codex
- Cursor
- any MCP-compatible assistant
Use cases
Where a company brain earns its keep.
Employee onboarding
New hires ask the assistant instead of five colleagues, and get answers grounded in how your team actually works.
Project handoffs
When someone moves on, their context stays behind: status, decisions, files and open questions.
Sales & customer knowledge
Proposals, objections, case studies and pricing history, ready when the next deal needs them.
Marketing & brand
Brand guidelines, tone of voice and approved claims, applied to every draft and image.
Operations & SOPs
Checklists and procedures that assistants follow step by step, not just link to.
Product decisions
Research, specs and the reasoning behind them, searchable long after the meeting ends.

Questions
Frequently asked questions
What is a company brain?
A company brain is a shared, AI-ready knowledge base that holds a team's documents, decisions, procedures and know-how, so AI assistants can search it and build on it while they work, and save new knowledge back.
How is it different from a wiki or knowledge base?
A wiki is written for people to browse. A company brain is used directly by AI assistants: they search it when they start a task, cite what they find, and write useful results back, so the knowledge stays current without a separate documentation effort.
Which AI assistants can use our company brain?
ChatGPT, Claude, Claude Code, Codex, Cursor and other MCP-compatible assistants. Teammates can use different assistants with the same workspace.
How does the AI find the right document?
Brainlet combines keyword search with semantic search, so it finds documents that match the meaning of a question as well as its exact words. Results show which file they came from.
Does Brainlet record every conversation automatically?
No. You decide what goes in: ask your assistant to save a decision, a document or a procedure, or upload files directly. Personal preferences stay separate from knowledge shared with the team.
Who can see what's in it?
Members of a workspace share its files, memory and skills. Everyone also has a private personal workspace. Connected apps such as Google Drive only return what each person's own account can access.
