Coaching
What can Hermes Agent do with Memory.fit?
Works while you train
Hermes Agent keeps going in the background: weekly reviews, plan tweaks and fueling prep are ready when you are.
Re-plans around real life
A short night, a work trip or a sore calf: it moves sessions and says why, and you can undo it in one tap.
Fuels every long session
It writes the in-session fuel plan, gel by gel and bottle by bottle, and you see it in the app before you start.
Writes your weekly review
What went well, one thing to fix and next week's focus, posted to the app every Monday.
Remembers what works
It saves the lessons: the gel that sits well, the taper that worked. Every agent you use reads them.
You stay in charge
Plan changes are opt-in, every action shows in your feed, and you can disconnect at any time.

Something not working?
- Unauthorized or 401. The key was mistyped or revoked. Create a new one in the Memory.fit app and paste it again.
- Too many calls. Each connection has an hourly limit. Wait for the time Memory.fit gives you and try again.
- Hermes Agent doesn't use Memory.fit. Mention Memory.fit in your message ("check Memory.fit", "use my Memory.fit data"), or switch the connector on for the chat if Hermes Agent asks.
- The numbers look old. Memory.fit shows what your apps have synced. Open your watch's app and Apple Health once, then check Settings → Health data in the Memory.fit app.

No. Hermes Agent is the coach. Memory.fit gives it your training data, your plans, your fueling and a lasting memory of you, and shows it all in the Memory.fit app.
Your workouts, sleep, daily metrics, fuel log, goals and plans. You choose what it can change: reading is always on, changing your plan is opt-in.
Only if you allow it. Every change shows in the app with Hermes Agent's reason, and you can undo it in one tap.
Memory.fit is $9 a month or $69 a year, with 7 days free. Hermes Agent itself: Self-hosted.
Garmin, COROS, Polar, Suunto, Wahoo, WHOOP, Oura, Withings, Apple Health, Health Connect, intervals.icu and TrainingPeaks connect directly. Nutrition apps like MyFitnessPal and Cronometer arrive through Apple Health and Health Connect. Strava shows inside the Memory.fit app only, because Strava doesn't allow its data in AI tools.
Yes. Connect as many as you like. They read and write the same memory, so nothing is lost when you switch.
