Finish Your Workout.
Your AI Coach Takes It From Here.
No new apps. No manual logging. Connect your Strava account, and VibeWriter's AI automatically evaluates every workout, generates creative titles, tracks your goals, and summarizes your training — without you lifting a finger.
How It Works
Connect Strava
One click, ten seconds. Authorize VibeWriter to read your activities and you're done.
Train Like Normal
Use Strava, Garmin, your watch — whatever you already use. Nothing changes about your routine.
AI Does the Rest
Within seconds of finishing, your AI coach evaluates your workout, writes a title, and updates your training summary.
Everything Happens Automatically
AI Workout Evaluations
Finish a workout on Strava, and within seconds your AI coach analyzes your pacing, effort, and intervals — then posts detailed feedback right to your Strava activity description.
Creative Activity Titles
Boring "Morning Run" titles get automatically replaced with AI-generated titles that capture the vibe. Customize the tone with your own prompt, or let the AI surprise you.
Weekly Training Summaries
Every week, your AI coach synthesizes all your workouts into a training summary — volume, patterns, and progress. Like having a coach review your training log.
Goal Tracking
Tell the AI what you're training for — a marathon, a faster 5K, getting back in shape — and it weaves goal progress into every evaluation and summary.
Native iOS App
Check in on your training anywhere. The iOS app gives you your AI training summary, weekly stats, goals, and activity history — all synced automatically.
See What Your AI Coach Says
Strong negative split today. Your last 2 miles averaged 7:12/mi vs 7:45/mi in the first half — that's the kind of back-end speed that wins races.
HR stayed controlled through mile 4 before drifting up, which is exactly what you'd want in a tempo effort. Lactate threshold work like this is key for your April half marathon goal.
One thing to watch: your cadence dropped below 170 in miles 3-4. Try to keep it consistent — it'll help with efficiency as the distance increases.
Your Data, Your Control
We only access what's needed to coach you — your activity data. Evaluations are generated per-workout and posted directly to your Strava activity. We never store personal information beyond what Strava provides, and your data is never used to train AI models. Connect in seconds, disconnect anytime.
