Ask your body
anything.
freddy puts all your sources in one place for your AI. Garmin, Apple Health, Health Connect and 100+ more, straight into Claude, ChatGPT, Grok Bot, Muse and any agent that speaks MCP. Stop staring at dashboards. Just have the conversation.
Your devices know everything.
Their apps tell you nothing.
You're collecting more signal than any athlete in history: sleep, HRV, glucose, power, lifts. The apps that ship with it ask you what you want for breakfast.
Three apps. Three dashboards. Zero answers.
You open Garmin. Then Apple Health. Then Hevy. Each one shows you its own numbers. None of them sit side by side.
One MCP. One conversation.
Connect freddy once. Then ask Claude, ChatGPT, Grok Bot, Muse or your favorite agent the question you actually have. They'll pull from your real numbers instead of guessing.
Built for the way
you track.
Three kinds of people get the most out of freddy. Find yourself, then steal their questions.
Athletes
Training load, recovery, race readiness. Ask hard questions across every session you have ever logged.
Biohackers
Run your own experiments: your AI sets your sleep against your training and your bedroom air. Test what actually moves your numbers.
Longevity & healthspan
The long game: resting heart rate, HRV, weight and sleep drift measured over years, not weeks.
Three minutes.
Then ask anything.
No new login to remember. freddy lives inside the AI tools you already use.

Yes. freddy is read-only on every account you connect. Tokens are encrypted at rest with AES-256, and we never sell, share, or train on your data. See our Privacy Policy for the full posture.
Yes, every connection is revocable from your dashboard. Disconnecting wipes all data we hold from that source within minutes.
Any MCP-speaking client. Claude (freddy is in Claude's directory) and ChatGPT (freddy is an official ChatGPT app) are one-click. Grok Bot, Muse, OpenAI dots, Gemini, Grok, Perplexity, Cursor, Codex, Manus, OpenClaw, Hermes and Claude Code each have a short setup guide in our Help center. Instinct and Hark are experimental. Set freddy up once per client and it works in that client from then on.

Yes for Grok Bot, Muse and OpenAI dots. In Grok Bot you ask your Bot to add freddy as a custom MCP server. In Muse you ask it to create a Custom Connector. In a dot, you connect freddy as a ChatGPT plugin and your dot uses it too. Availability depends on your OpenAI plan and region. Instinct and Hark are experimental. Neither publishes steps for adding your own MCP server, so our guides show what to try. See Grok Bot, Muse, dots, Instinct and Hark.

No. freddy hands your raw numbers to the AI you already use, and your AI does the thinking. freddy does not compute scores.
