FAQ

Do I need my own API key?

Yes. During setup you give Fibonna your own OpenAI or Anthropic API key. Your stack uses it for five jobs: compiling memories into pages, checking and distilling lessons, extracting lessons from a handoff, summarising a session for a handoff, and the Ask feature when it cannot answer locally. Fibonna holds no AI key of its own for pilot stacks, and the provider bills you directly. The privacy page has the full list of what each job sends.

Which agents work with it?

Claude Code first, as an MCP connector. ChatGPT as a custom connector. Any other MCP client that supports sign-in can connect to the same memory; Claude Code is what we support first.

Which operating systems?

The memory works from any machine. The npx fibonna CLI supports macOS and Linux. Dispatched worker sessions run on a paired Mac.

How do I apply?

Fibonna is application-only while the founding cohort fills. Use the form on the home page: what you are building, which agents you use and how many machines you run them on. We read every application and reply from [email protected].

What does it cost?

The price is in the invitation. The founding price is locked for as long as you stay subscribed. Your model usage is billed by your provider, on your own key, and is not part of it.

What leaves my machine?

What your agents write to Fibonna through the connector: the notes they save, the handoffs they write, the tasks they create. It lands on a stack that is yours alone, one backend and one database used by nobody else. The privacy page lists, in full, who receives what, and the security page says how it is protected.

Does it replace my agent's instruction files?

No. Keep them; they are the right place for rules you write by hand and that load at the start of every session. Fibonna holds what outgrows them: decisions, lessons and open loops that build up over weeks. How memory works has the detail.

Can I export everything? What if I leave?

Yes. You can ask to see, export or delete everything Fibonna holds for you, and we do it within 7 days. When you leave, we delete your whole stack. Backups of a deleted stack are purged within 30 days.

Is it open source?

Not today.

Where is Fibonna based?

Singapore. Questions to [email protected].
