How it works
Add your diary as a connector, sign in to Mast Cell Decoded and press Allow. Then it's there on your phone, the web and your desktop.
For Claude Code, other MCP tools, or settings files: make a key on your account page and paste it in. We show you exactly where.
Developers can use the same data as a JSON API, with a key, or let users sign in with OAuth.
A peek inside
Your assistant reads what you've logged (how you felt, flares, what you took and ate, your cases and findings) and answers from it.
Sample entries
What you get
How you felt, flares and symptoms, medications, food, activity and measurements, day by day.
Your hard days and the culprits you named, solved, cold or still open.
Each day's MCAS score where you were, and the days ahead.
What works for you, what doesn't, and your symptoms, discoveries and labs.
It reads your diary, and only yours. If you choose, let it log entries and update your findings, cabinet and cases too.
Disconnect an app or revoke a key on your account page, and it stops at once.
A note
When your assistant reads your diary, that information goes to the AI company behind it, under their privacy policy, not ours. Connect only an assistant you trust with your health information.
Private by design
All your information is encrypted before it's stored. Your privacy is important.
No advertising, no data brokers. We don't share or sell your info with anyone.
Delete any entry, or your whole account and everything with it, any time.
The AI Connector is part of a subscription, with the Health Diary, the Weekly Forecast and every tool to come. Every new account gets a free week of all of it, no card needed.
