About monthlet
monthlet is a local-first AI note-taking application that transforms unstructured brain dumps into formatted notes through natural language commands. Users input raw ideas, fragments, or bullet points, then instruct the AI to generate a complete document with layout, banners, columns, and tabs automatically applied. The app supports real-time refinements by allowing users to request specific changes to any part of the note without regenerating the entire document. Beyond standard note-taking, monthlet enables the creation and editing of spreadsheets with formulas and formatting, live charts that update with sheet data, and instant theme restyling via simple requests. Notes can be organized by calendar views, linked through a visual map, and tagged for filtering in a gallery. The application stores all notes as plain HTML files locally, ensuring data ownership and long-term accessibility without vendor lock-in. AI processing can be handled either through the user’s own API key for Claude, ChatGPT, or Gemini, or via a subscription service that manages the AI backend internally.
