Coaching
What can Grok Bot do with Memory.fit?
Works while you train
Grok Bot 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.

About Grok Bot
What is Grok Bot?
Grok Bot is xAI's always-on agent. It keeps working after you close the app, so it can write your weekly review, re-plan a week after a bad night's sleep or prepare race-day fueling while you train.
What is Memory.fit?
Memory.fit is the data and memory layer for the AI you already use. It connects Apple Health, Withings and TrainingPeaks (and shows Strava in the app), keeps your goals, plans and fueling, and shows it all in the Memory.fit app. Your AI does the talking; Memory.fit does the remembering.
