# Your Mac already knows all this.

Your notes, messages, mail and history, exported as Markdown you own, kept in sync, ready for Claude and any AI tool. All local, nothing uploaded.

Notes, mail, messages, calendar, books, browsing. Alto Index copies every one into plain markdown files.

## Files on your disk, not a database.

Point it at a folder. Each source becomes a folder of .md files that outlive any app, including this one.

## Claude reads it directly.

Claude Desktop, Claude Code, Cursor, Obsidian. Anything that reads files can read your whole Mac.

## It stays current by itself.

Kept in sync as you go, only what changed. Every run on the record, so you can see what moved.

## It never leaves your Mac.

No account, no cloud, no server. Read locally, written locally, and yours to move anywhere.
