What AI-native looks like
Semantic Search
Search by what you meant, not what you typed.
Wiki Synthesis
Pick a tag. Get a wiki article — with citations back to the notes that wrote it.
Agentic Chat
Chat with your notes. It cites them; it doesn't invent them.
Spatial Canvas
A force-directed map of your thinking. Related ideas drift toward each other on their own.
Auto-Tagging
No folders. Atomic tags every note the moment it lands.
MCP Integration
Plug it into Claude or Cursor. Your notes, in your agent's hands.
Wikis, written by your notes.
Pick any tag. Atomic generates a full wiki article from every note, clip, and saved page underneath — with inline citations back to the source atoms. Articles regenerate as you add more.

Search by meaning, not strings.
Atomic embeds every atom into vector space. Type a question; get back ideas — even when your notes don't use the words you searched for. Find a note from six months ago without remembering what you titled it.
Learn moreEverything is an atom.
Notes, articles, web clips — anything you save becomes an atom. Each one gets tagged, embedded, and connected the moment it lands. No folders, no schemas, nothing to maintain.

Your daily briefing
A summary of everything new in your graph. Click any citation; the source atom lights up on a mini-canvas.
One server. Every device.
Your server is the source of truth. Every client points at it: desktop, iOS, browser, MCP. Run the whole stack on a laptop, or self-host and sync every device.
