Notch

Notch is a chat-first AI workout coach. You text your coach like you would a real trainer — it remembers every set, rep, and weight you log, tracks your progress over time, and pushes progressive overload as you improve. Paste in a training plan to get started, then just chat through each workout: your coach suggests weights/reps for each exercise and logs whatever you actually did, even if it's different from the suggestion.
