Pulse AI Coach (GPT, Claude, Gemini)

Web and more settings details: https://nioquant.com/coachpulse CoachPulse is an AI coaching data field for Garmin watches. It reads your biometrics during a workout (heart rate, pace, body battery, stress, and more) and delivers real-time coaching cues directly on your watch screen. No app switch, no phone unlock. You bring your own API key from OpenAI, Anthropic Claude, or Google Gemini. Pick who coaches you from 7 personas: Supportive Partner, Drill Sergeant, Sports Scientist, Zen Master, Old-School Trainer, Hype Friend, or Race Tactician. Racing? Set a target distance and goal time and every cue tracks your live gap to the plan and your projected finish. Press the lap button for an instant read of your effort. Stop the timer and get a debrief with the takeaway that matters. And the coach remembers: notes from your last workouts feed into the next session briefing, so it knows how your training has been going. Note: Your own subscription to one of the AI models/APIs is required. How to use 1. Install CoachPulse from the Connect IQ store. 2. In the Garmin Connect app, add CoachPulse as a data field on any activity screen. 3. Open CoachPulse settings in the Connect IQ section and enter your API key, provider, and model. 4. Start your activity and swipe to the CoachPulse screen. It shows "Monitoring..." while idle and cues appear automatically when triggered. A full-screen single data field gives the most room for longer cues.
