Turning daily life into Japanese practice: write how your day went in Chinese, and AI writes a Japanese diary that is truly yours.
- Upload a photo of the day, choose a mood and describe what happened in Chinese; the AI writes a first-person Japanese diary entry based on the content rather than translating word for word
- Limits grammar and vocabulary to the JLPT N5–N1 level, with Chinese translation, furigana, vocabulary and grammar notes, plus read-aloud
- Switch between AI providers such as OpenAI, Anthropic and Gemini, or set a custom OpenAI-compatible endpoint (base URL and model) and fetch the latest model list in one click; API keys are encrypted on the server
- Review past entries in calendar or list view; a mobile-first web app built with React, Supabase and Vercel
