Memory.fit is $9 a month or $69 a year, with 7 days free, for every device and every AI you connect. Grok's own plan, if it has one, is separate.

Does it work outside the US?

Memory.fit works in every country, and Grok's requirements name no region.

Is my Zwift data safe?

Grok gets only the permissions you allow, every change shows in the Memory.fit app with who made it, and you can disconnect Grok or Zwift at any time.

Can I set it up on my phone?

Yes. In the Grok app, open Settings › Connectors, scroll to Custom Connectors, tap Custom Connector, then Connect. Name it Memory.fit, paste the address and tap Add Connector, then sign in with your Memory.fit account.

Connect Zwift to Grok

Yes, through intervals.icu. Zwift shares with intervals.icu, the Memory.fit app reads it, and once you add one Memory.fit address to Grok, Grok reads your rides and runs, duration and distance, and heart rate.

Grok can also write your plans back to Memory.fit, where you see them in the app.

What Grok needs: sign in, about a minute.

What it reads

What Grok reads from Zwift

Through intervals.icu: Zwift sends your rides there, and Memory.fit reads intervals.icu.

Memory.fit reads each finished session, not the steps of the Zwift workout you rode.

What it can do

What Grok can do with it

Plans written back: Yes. Grok reads your training, sleep and fuel, and can plan around them.
Meal photos: In part. Grok sees your meal photo and logs the meal, but can't hand the photo itself to Memory.fit unless it can run code with internet access.
Where it runs: grok.com and the Grok apps.
Good to know: This page is for Grok, the assistant on grok.com and in the Grok apps, not Grok Bot. You add Memory.fit once in the Grok phone app, under Settings › Connectors › Custom Connector, and Grok reads your Zwift rides in any chat after that, with no connector to pick.

Limits

Limits, said plainly

Memory.fit has no direct Zwift connection yet. Today your Zwift sessions come through intervals.icu, which links to Zwift itself.
Link Zwift to intervals.icu directly, not through Strava: activities that came from Strava stay out.
Zwift doesn't reliably sync to Apple Health or Health Connect, so we don't count on that route.
Your AI's own subscription is separate from Memory.fit's.
