HRV MEETS AI

Ask your AI
how you're recovering.

BeastHeart captures your HRV every morning and exposes it via MCP — so Claude, ChatGPT, or any AI assistant can combine it with your sleep, training, and health data from other sources.

BeastHeart mascot — beast with glowing heartbeat

BUILT FOR ATHLETES WHO MEASURE EVERYTHING

Medical-grade HRV capture. AI-native data layer. Zero fluff.

YOUR DATA, INSIDE EVERY CONVERSATION

BeastHeart is an MCP server. Your AI assistant calls it like any other tool — and combines it with sleep from Whoop, training load from Garmin, or anything else you've connected.

Y

How's my recovery today? Should I do intervals or easy miles?

Your BeastHeart readiness is 8/10 — well above your 30-day baseline (mean lnRMSSD 3.62 vs your 3.84 today). Whoop shows 85% recovery with 7.5 hours of sleep. Garmin has your training load at moderate with 48 hours since your last hard session.

You're clear for intervals today. Your body has capacity.
