ChatGPT Health vs revns: answers from your records or a plan you can work to
OpenAI introduced ChatGPT Health in January 2026: a health space in ChatGPT where you can link wellness apps such as Apple Health and, in the US, medical records. OpenAI says connected data is not used to train its foundation models, and ChatGPT asks before using it by default. It is built to answer health questions from your data. revns is a tracker with a goal and a plan that an assistant can work on. Its MCP server connects ChatGPT, Claude, Claude Code and Cursor to the same state: your day score, trends, goals and week plan, and, if you allow it, tools to log, set goals and plan days. It gives training guidance only, not medical advice. If you want to ask questions about lab results and records, ChatGPT Health is built for that. If you want the assistant to keep a plan with you, revns holds that state.
| ChatGPT Health | revns | |
|---|---|---|
| Where your data lives | Linked sources inside ChatGPT | In the tracker; any MCP assistant reads and writes it |
| Which assistant | ChatGPT | Claude, ChatGPT, Claude Code, Cursor, any remote MCP client |
| Medical records | US hospital systems, One Medical and Function Health | No. Training guidance only, no diagnosis |
| Goals and a week plan that persist | Not the focus | Goal pace with a range; a week plan written into each day |
| Daily score and morning brief | No | Training, sleep, meals and mood in one score, with a brief |
| Permissions | Linked sources; asks before using by default | Separate read and write scopes; disconnect any assistant any time |
Where it is the better choice
ChatGPT Health reaches medical records and lab data that no fitness tracker does, and ChatGPT's reasoning is strong. For questions about records and results it covers ground this does not, and it is not a replacement for a clinician.
