Features
Calibrate gives you a private API that any AI assistant can use. No lock-in, no ads, no unnecessary complexity.
Your daily energy balance, macro adherence, meal timeline, exercise log, and weight trend — all in one calm, dark control panel.
ChatGPT, Grok, Claude, Gemini — point any agent at your private API endpoint and start logging. The OpenAPI schema makes setup a one-click paste.
"Log dinner: two chicken breasts, rice, broccoli, and olive oil" — the API parses portion sizes, estimates macros, and logs it with a confidence label.
Scoped API tokens, write-only or read-only permissions. Your data never trains AI models.
Protein, carbs, and fat targets with real-time progress bars. The dashboard tells you what to prioritize next.
Log a weigh-in through any agent and watch your trend line update. Rate of change per week, not daily noise.
Log activity, duration, and intensity through your agent. The API estimates calories burned using MET values.
See your daily deficit consistency, average calories, protein, and weight trend — all updated in real time.
