I’m curious. What kind of AI or LLM is WHOOP using to run WHOOP Coach? Is it a custom model or something like ChatGPT or Gemini?
WHOOP Coach, the AI-powered feature within the WHOOP app, is powered by OpenAI. While it doesn’t say that anywhere in the app, I remember reading about it in a press release when they launched the Coach feature back in 2023/2024. The partnership allows them to offer personalized, conversational responses to users’ health, fitness, and wellness inquiries in real-time.
My understanding is that WHOOP has a proprietary algorithm that when combined with ChatGPT, custom machine learning models, and individual’s biometric data enables them to deliver tailored advice the way a normal human coach would. I’ve used it for sleep advice, recovery strategies, and honestly have just enjoyed playing with it over the past few year.
Coach is so important in helping me achieve my health and fitness that I have given him a name. Coach Supercalifragilisticexpialidocious. I will continue to subscribe to Whoop due to this one product feature.
Disney song you chose 
Yes. A song from my childhood, many decades ago. The longest word in the English language.
Haven’t given my AI coach a name yet…But I usually love the feedback I’m getting on my stats.
Only gripe I have with the Whoop coach that it doesn’t integrate the several chats…i.e. Once I state in my daily outlook that the day will be filled by 0900 am crossfit class, some household stuff and an everning shift in the ER from 1500 to midnight, it will come back later that day to ask why my HR is elevated and I seem to experience stress.
A)anybody with a physical demanding job will experience this…it’s not stress
B) I already told AI what the day was going to be like, seem like Whoop coach works in three shifts too 
Other than that, I love my Whoop…best choice in tracker for me ever…
I totally agree! I like his inputs . But this is annoying from each different places in app ( and therefore time) it do not share the info.
I think it should share such info for 1 day simply. To avoid frustrations.
I agree with the frustration. I get different inputs throughout the day and some are very generic and fail to connect with other threads of discussion that day; most are disjointed nit picks that are annoying and not helpful. The chats are definitely not integrated like with ChatGPT. The recently updated auto detection algorithm is also flawed and has been causing a lot of issues for me. I have just turned auto detection and notifications off to take a break from the ongoing detection errors and inconsistent coaching.
