Normalized, deduplicated data
When your Apple Watch and Oura Ring both report HRV, Fulcra picks the right one. When two devices log the same run, Fulcra normalizes them. Your agents reason from clean data, not noise, or can see the raw data and compare devices.
Your data, your keys
Each user's data is encrypted with their own dedicated rotating keys. You control exactly which agents, coaches, or family members can see which data and you can revoke access at any time. Agents get just the data they need to answer your questions, not all of your data forever.
Full audit trail
Every agent action is logged. You can see what any agent reads, when it reads it, and from what source.
200+ sources, one timeline
Apple Watch, Oura, Garmin, Whoop, Dexcom, Libre, Withings, Google Calendar, location, and more. Direct API connections for non-Apple sources through Fulcra, bypasses Apple Healthkit.
Any agent, any tool
Fulcra isn't locked to one agent. Connect Claude, ChatGPT, OpenClaw, Hermes, a notebook, or an agent you built yourself.
Manual analysis too
Not everything needs an agent. Query your data in Jupyter notebooks, Gemini in Colab, Copilot in Excel, or any analytics tool. Fulcra is a data layer, not just a chatbot backend.
Custom annotations
Log what your devices can't capture: meals, supplements, medications, mood, stress, sleep environment, symptoms, and experiments.
Your complete health timeline
Every data point — from wearables, apps, and your own annotations — organized into one scrollable, human-readable timeline. Search across years of history to spot patterns no single app can see.
Shared awareness
Give your coach access to training load. Share sleep data with your doctor. Let a family member see what they need to. Each person sees only the slice you choose — with a full log of every access.
