Everything a second brain needs
Fast capture, smart connections and a map you can finally navigate.
Capture from anywhere
Save a thought in a second — from the web (⌘K), the iOS and Android apps, or Apple Shortcuts. Add voice notes and attachments, capture from the share sheet, a home-screen widget, even offline.
AI analysis
Every note is processed by AI — summarized, given context, its themes recognized. You ask in plain language and get answers from what you saved.
Neural links
Munwyn finds meaningful links across what you know — even where you wouldn’t expect them. Notes stop being islands and start talking to each other.
2D & 3D atlas of your mind
Your knowledge as a living map — explore it in 2D and fly through it in 3D, on the web and in the iOS and Android apps.
Reflection
Returns, weekly letters, compost, counter-arguments and tasks — a second brain that helps you think, not just store.
