monthlet AI

Join the monthlet AI closed beta

monthlet is a note app for Mac and Windows where the AI writes the note for you: describe what you want in plain words, and it builds the note, layout and all. Your notes stay as files on your computer.

monthlet AI lets you use the AI without getting an API key. Before the official release, we're inviting 15 people to try it. The beta runs from early November 2026 to January 10, 2027, and it's free. If you keep sending reports, you'll get 6 months of monthlet AI for free after the official release.
