About this project

Endorphins AI started from a bit of curiosity, every activity carries so much data about pace, effort and heart rate, yet the name attached to it rarely tells that story. It felt like there was a more interesting way to capture what a session actually felt like, using the data already there.

This is a solo side project built on cloud infrastructure, using LLMs to generate names and descriptions that actually reflect how an activity felt, calm and easy, or a genuine grind, based on real effort data, not just a template.

Frequently asked questions

Common questions before connecting your account

Is this free?
Yes, it's completely free! Only planning to add an optional donation in the future to help cover cloud infrastructure costs.
Will it overwrite names I've already edited manually?
Only new activities are renamed automatically when they're first created on Strava. If you manually rename an activity afterwards, the AI does not touch it again.
Does it work with devices other than Garmin?
Yes, any activity that lands on Strava gets processed, regardless of the source device. The AI adapts to whatever data is available for that activity.
Can I disconnect at any time?
Yes. Go to strava.com/settings/apps and remove the connection. This immediately revokes our access and no further activities will be processed.
What data does the AI actually see?
Only activity stats, such as, distance, duration, heart rate, pace, elevation, and sport type. GPS coordinates are processed transiently for location lookup and are not stored. See our Privacy Policy for full details.
Why is it limited availability right now?
The API currently supports a limited number of users. If you have trouble connecting, use the form below and we'll expand access as soon as possible.
What do the different tone options mean?
Mixed: A short story plus key stats. The default for most sports.
Narrative: Pure storytelling, no stats line.
Data: Numbers first, minimal narrative.
Humor: Playful and affectionate, never mocking. Jokes scale to the effort of the session.
Will it overwrite a name that came from Zwift or another training app?
No. If an activity's name or description mentions a known training platform like Zwift, TrainerRoad, Peloton, or similar apps, we leave it exactly as is. Everything else, including Strava's own default titles like "Morning Run", gets an AI-generated name as usual.
