Diffyn

Soma is a zero-friction AI note app for capturing ideas the moment they appear. Write first—Soma auto-generates titles/topics and connects related notes by meaning, then lets you rediscover them via semantic search or a graph view. No “where should I put this?” pause—just capture, connect, and find.
