Suunto built its own AI coach. Why Heza doesn't have one
By Jo Kassis 2 min read
On 15 October Suunto launched its AI Coach. It’s a chat inside the Suunto app that looks at your workouts, sleep, HRV, recovery and training load, and it can build structured workouts and routes that you then send to your watch.
It came out with the new Race 3S. If you activate that watch by the end of December, three months of the coach are included. Other Suunto watches get it in early 2027, and Suunto hasn’t said yet what it will cost after that.
It makes sense for Suunto. If everything you do is recorded on one watch, a coach that knows that watch well is useful.
Heza could have its own AI too. I decided not to build one.
Bring your own AI
For me it comes down to freedom of choice. Most people already use an AI, free or paid, and it already knows how they talk and what they’re after. I’d rather Heza works with that one than ask you to start over with mine and pay for one more subscription.
It also means you can change your mind. If a better AI comes out next month, you connect it to Heza and carry on with the same data. Your food, training and watch data stay in one place, and whichever AI you choose reads it there.
The catch
Connecting your own AI takes a few steps, and “MCP” isn’t a word most people want to learn.
So on the Connect screen in Heza there’s now a Need help? box. Tell us where you got stuck, and we’ll email you to find a time for a quick call and set it up with you.
Maybe one day there will also be a built-in AI for people who’d rather not set anything up. If that happens, it will be optional.
