A notes app that connects everything you know
Write notes and keep recipes, places, bookmarks and people in the same place. Link them with tags and see how they relate on a knowledge graph.
More than notes
Notes sit next to recipes, places, bookmarks, people, hardware and software, so the things you know are not scattered across different apps.
Tags and links
Tag anything and link items to each other. A note about a trip can point to the places, the people and the budget that belong to it.
Find it again
Search across everything at once, and explore the knowledge graph to see how your notes and entities are connected.

- Can my AI assistant read my notes?
- If you want it to. Create a token in your profile and connect your AI assistant over MCP; you choose whether it can only read or also write.
