One knowledge base · Every AI client you use · Work and life
Plan it in ChatGPT.Build it in Claude Code.
CEPO is one knowledge base that every LLM and harness you use can read and write. Notes, tasks, and prompts, for the code you ship and the life you run. Think in any client, act in any other, and they all see the same thing. Review and track it all on cepo.ai.

How it plays out
Start in one place. Finish in another.
Three handoffs, from work and from life. The left half is where you were. The right half is where it ended up.
01 · Plan, then build
A PRD written in one chat becomes stories in another.
No copy-paste. The next session finds it by name.
02 · A task, mid-conversation
Something to do later? Say so. Keep talking.
A trip, a renovation, a busy week. The task lands in your list with the context it came from.
Renew the kids’ passports
due 1 Mar · from ChatGPT · linked note “Lisbon trip, May”

03 · Find it later, anywhere
You already worked this out once. Don’t scroll for it.
A decision made in one chat months ago, answered in another today.

Three quotes. Marta’s crew: fixed price, handles permits, +2 weeks. Chosen for the fixed price.

Who it's for
Not just for people who ship code.
If you write code
PRDs, stories, and decisions that outlive the session.
Plan in a chat, build in Claude Code or Cursor, and pick up tomorrow exactly where you stopped.
If you run a team
Research, compare, decide. Then find it again.
Vendor calls, meeting follow-ups, the reasoning behind a choice. Saved with tags from whichever assistant you were in.
If you run a life
Trips, the house, the kids, the doctor’s advice.
Ask in whatever app you have open. The plan, the task, and the answer land in one place you can search from any of them.
What's inside
Three apps. On cepo.ai, and from any client.
cepo.ai is the web app: review notes, track what’s open, edit prompts. Every client reads and writes the same place.
- Knowledge Base
- Markdown notes with tags, full-text search, pinning, and diagrams. Agents save research and decisions here as they work; you can too.
- Tasks
- Create, update, and complete tasks from any client, mid-conversation or on purpose. Review what’s open on cepo.ai.
- Prompt Library
- Save and version prompts. They appear in your client’s prompt picker, not its tool list.
The technical bit
Connect once per client. They all see the same notes.
Your account comes with a Default MCP endpoint. Streamable HTTP with OAuth 2.1. Each client signs in once; tokens refresh on their own.
