Release Notes

1.0.0

Released 7 October 2026

The first release of FERMI: ask questions about your own documents and get answers with the passages they came from, on your own computer.

Asking

• Ask in plain words on the ask page.
• Every answer shows the passages it came from; open one to see its page.
• When your documents do not answer the question, FERMI says so.
• Answers are marked as AI-generated.
• AI tools that speak the Model Context Protocol can search your documents through FERMI.

Your documents

• Reads PDF, Word, Excel, RTF and HTML files in the folders you choose.
• Never writes to your documents: nothing in them is created, changed, moved or deleted.
• Reads each file once, and again only when it changes.

Privacy

• Runs on your own computer, and listens on this computer only until you pair a phone or another computer.
• The language model downloads when you choose, or installs from a folder or drive with no connection.
• Cloud providers are off unless you turn one on.
• No account, no telemetry, no analytics.

Running it

• Apps for Windows, Mac and Linux on x64 and arm64, for iPhone and Android, and a Docker image for Linux.
• FERMI checks for updates once a day while automatic updates are on.
• Updates are verified against a signed checksum list before they run.
• FERMI keeps its index, model and settings in its own folder, never beside your documents.
