Your meals and glucose, read in context.
MARU turns the AI you already use into a personal health coach. Your meals, CGM readings, and sleep reach ChatGPT, Claude, or Gemini through MCP — so every conversation starts from your real life, not a blank page.
MARU is currently available in Japanese. An English release is on the way.
Snap
Take a photo of your meal. AI reads it in seconds.
Connect
Your CGM (FreeStyle Libre) and Apple Health data come in automatically.
Understand
Weekly reports surface the patterns behind your numbers.
The AI you already use, with the context only you have.
MARU connects your meals, glucose, and sleep to ChatGPT, Claude, or Gemini via MCP (Model Context Protocol). There is no new chat app to learn — your usual AI simply starts understanding your body.
Data is not a report card.
We treat it as a letter from your body. MARU never judges you by your numbers — it reads the context behind good days and hard days alike, and hands you one small, doable next step. A companion for the journey, not a watchdog.
Start with tonight's plate.
MARU is in invite-only beta in Japan today. If you would like to hear when the English version opens up, we would love to know you exist.
