Cohestry

“Your thinking, made explorable.”

Cohestry turns your notes into a connected second brain you can explore, develop, and rediscover. It links notes that share names, words, or tags without manual linking, shows the reason behind every connection, and lays your whole library out as the Brain — a 3D map you can turn, zoom, and search. Apple Intelligence suggests deeper links on-device, and there is no account or server: sync runs through your private iCloud. Cohestry is now on Mac too — the same App Store download, with ⌘K, Apple Notes import, and the Agent Bridge for Claude, Codex, and Cursor.
