Tell GPT what you want.
Start your workout instantly.
PromptFit connects ChatGPT to a live workout renderer. Describe your session, and GPT compiles a structured plan and links you directly to it — no app, no account.
How it works
01
Describe your workout
Tell GPT what you need — muscles, duration, equipment, intensity. It handles the rest.
02
GPT compiles & links
GPT calls the PromptFit API, gets a stable plan ID, and returns a direct play link.
03
Tap and go
Open the link on any device. Your workout starts immediately — animated, timed, guided.
100 exercises, all animated
Every exercise in the library has a two-frame animation. Browse by muscle group, see the movement, copy the exact exercise ID for your GPT prompts.
