About

Tuno

Features
Read full description

Tuno is a private journal for quick thoughts, moods, voice notes, images, and files. It keeps writing close to a chat: start a journal, add entries as messages, record a mood quickly, and revisit your history as a timeline. AI is optional. If you add your own API key or enable a local text model, Tuno can help summarize recent context, answer questions about a journal, and organize tags. If you do not configure AI, Tuno works as a simple local journal. Highlights: - Message-style journals for everyday thoughts - Mood check-ins with customizable icons - Voice notes with saved audio and transcription - Images, files, and structured ZIP import/export - Web access on the same Wi-Fi for desktop writing - Optional AI providers and local text models - Data stays on your device unless you choose to export, sync, or call an AI provider
