A personal data engine
for the LLM era.

Sync your iMessages, Mail, Calendar, Photos, Notes, Reminders, and a handful of cloud sources into one local SQLite database on your Mac. Query it with the bundled chat UI, with Claude Desktop via MCP, or with your own Python tools.

Free. Open source. No account. No subscription. Nothing leaves your Mac unless you point a hosted LLM at it.

What did Brian text me last week?

Three texts last week — confirmed Friday dinner, asked about the marathon, sent a link.

Ask anything

Use Fibra's chat panel, or point Claude Desktop / Cursor at the bundled MCP server. Bring your own LLM.

Your scattered data,
finally talking to each other.

Built for the LLM era

Lives on your Mac

Your data sits in a single SQLite file on your computer. No account. No backend. Nothing leaves unless you point a hosted LLM at it.

Bring your own LLM

Run a local model bundled with Fibra, or point it at Anthropic, OpenAI, Gemini, or Ollama. Use the chat panel, or expose Fibra as an MCP server to Claude Desktop and Cursor.

Syncs quietly

Connect once. Fibra keeps Apple-app data and connected cloud sources fresh in the background — no buttons to press, no schedules to manage.

Hackable by design

Drop a Python file in ~/.config/fibra/tools/ to add your own tools. Bundle prompts and tool subsets as YAML harnesses. Fork the whole thing — it's open source.

Bring your data home.
