A calm notes app. Capture a thought in a second and find it again later.
Kept clear. What we leave out makes room.
Everything you capture lands somewhere you can find it, and nothing is filed without your say-so. Sheaf does one thing: it keeps your notes, and keeps them legible as they grow, instead of turning into another pile to manage.
It speaks fluent assistant, too. A built-in MCP server lets the tools you already use read and write your notes for you — so you can hand off the filing and keep the thinking.
