  crossmem.dev — one memory, every ai

crossmem turns any web page into a structured memory — automatically.

Click Snapshot on an arxiv paper, a Wikipedia article, or a blog post. crossmem reads the page, generates an AI summary, and files it as a memory ball in your side panel. The raw source (PDF or screenshot) and a wiki-style markdown note are saved to your local filesystem or Google Drive.

HOW IT WORKS

1. Open any web page
2. Click Snapshot in the side panel (or right-click → Remember This Page)
3. AI summarizes the page and categorizes it (research, tech, resource, idea, action)
4. A memory ball appears with title, summary, source link, and category
5. Raw file (PDF/screenshot) + wiki markdown saved automatically

WHAT YOU GET

- Memory balls: color-coded by category, searchable, expandable
- Raw snapshots: arxiv PDFs downloaded, other pages screenshotted
- Wiki notes: structured markdown with frontmatter, ready for Obsidian or any editor
- Side panel UI: always accessible, never leaves your browser
- Right-click menu: "Remember This Page" or "Remember Selection"
- Bridge API: local WebSocket API for scripts and AI agents to drive crossmem programmatically

STORAGE OPTIONS

- Local: files saved to ~/crossmem/ (configurable) via the companion bridge
- Google Drive: summary files in your personal crossmem/ folder
- Both: use local for raw files, Drive for cloud backup

YOUR DATA, YOUR CONTROL

- No backend servers, no analytics, no telemetry
- AI calls go directly from your browser to your own API key
- Everything stored locally or in your own Google Drive
- Open source: inspect every line of code

Built for researchers, developers, and anyone who reads more than they can remember.
