trainedby.ai

Log your fitness goals, workouts, and notes for free — your AI remembers everything. Add wearable integrations to give it your real training load, sleep, and recovery data. Works with ChatGPT, Claude, and more.

AI fitness is broken. Because it starts from zero every time.

You describe your level, goals, recent workouts, and schedule. Every single conversation. The AI forgets everything the moment you close the tab.

You screenshot your watch data and paste it into ChatGPT, hoping it can make sense of cropped graphs and blurry numbers. It can't.

"I slept okay" when your HRV dropped 30%. "Easy run" when you spent 20 minutes in zone 4. What you tell the AI isn't what actually happened.

Your resting HR has been creeping up for two weeks. Your training load spiked 40% last week. The AI has no idea — because you didn't notice either.

Start for free. Add workout notes, goals, injuries, and availability. Your AI builds a training memory that grows over time — no wearable required.

Ready for real data? Link Garmin, Oura, Polar, or 50+ others. We translate raw metrics into meaningful insights: HRV trends, training load, sleep patterns, recovery signals.

Open your favorite AI assistant — like ChatGPT or Claude — and ask about your training. The AI already has everything. Your notes, your goals, your wearable data. No more copy-pasting.

We surface the trends and patterns that matter, so your AI assistant can give advice based on what actually happened.

If you're wearing it, we probably support it. One-time connection, automatic daily sync.

We don't believe you need another app with another dashboard, another feed, another notification. You already have the best personal assistant in history sitting in your pocket.

The missing piece was never the AI. It was thedata. These models are brilliant coaches, but they can't help you if they don't know you. So instead of building app number 10,000, we built a secure data bridge: your real training data, piped directly into the AI assistant you're already talking to.

We use the newModel Context Protocol (MCP)— a standard that lets AI assistants securely talk to your data. Today that's ChatGPT and Claude. Tomorrow it could be any assistant that supports this open standard.

Your AI assistant is the interface. We just make it smarter about you.

No dashboards, no feeds, no notifications. Just better conversations.

Any AI assistant that supports the new secure data standard (MCP) gets your training data automatically. Today that includes:

Your training data, notes, and wearable insights appear automatically in every conversation.

Claude sees your full training history and goals the moment you start chatting.

Google Gemini does not yet support the secure data connections (MCP) required for trainedby.ai.

As more AI assistants adopt this new open standard, they'll work with trainedby.ai out of the box — no integration needed from our side.

Should I do my long run tomorrow or take a rest day?

Looking at your data, I'd recommend a rest day tomorrow. Here's why: your resting HR has been 4 bpm above baseline for 3 days, your HRV is trending down 12% this week, and your training load jumped 38% last week. Your body is still absorbing that load. Push the long run to Sunday — you'll get more out of it when you're recovered.

Light mobility work or a 20-minute walk would be ideal. Your sleep consistency has been off too — try getting to bed closer to your usual 10:30 PM tonight. That alone will accelerate recovery.

Log goals, workouts, and notes at no cost. Pay only when you want automatic wearable sync.

Log workouts, set goals, add notes — your AI builds a training memory over time. No wearable needed, no card required.
