About

PressPlay is a hands-free audio coach. You pick a focus area, a length, a voice, and a detail level; we write a routine tailored to those choices and narrate every move over your chosen backing track while you exercise.

How it works

When you hit Generate, we ask a large language model (Anthropic's Claude) for a structured routine — warm-up, work sets, rests, cool-down — with per-move coaching text at your chosen detail level, from "just the name" to a ~400-word walkthrough covering setup, breathing, and common mistakes. A text-to-speech model (OpenAI's gpt-4o-mini-tts) converts each instruction into audio in your chosen voice and language. During the workout, the narration plays over your music and ducks automatically while the coach is speaking.

Health disclaimer

This app is not a substitute for professional medical advice, diagnosis, or treatment. The exercises it recommends are generic bodyweight moves; they may not be appropriate for your body, injuries, or conditions. Consult a qualified healthcare provider before starting any workout program. If a move causes pain (beyond normal muscular effort), sharp discomfort, dizziness, chest tightness, or unusual shortness of breath, stop immediately.

Privacy

Your configurator selections stay in your browser (localStorage). Workout requests and narration audio are cached server-side keyed by their inputs so repeat workouts are instant and don't burn through tokens. The app doesn't track or analytics-profile you. See Privacy for specifics.
