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.
What's New
VibeWriter ships often. Here's what landed recently.
VibeWriter now has a paid tier. Pro is $5/mo or $48/yr (billed annually at $4/mo, ~20% off). Every new account starts on a 14-day Pro trial — full AI Coach with persistent memory, goal-aware workout evaluations, training summaries and YoY rollups, full goal management, and ad-silenced Strava descriptions. After the trial, Free keeps your AI titles, wellness ingestion, and AI-grounded evaluations going; Pro adds the coaching layer on top. **Existing users are permanently grandfathered with full access — thank you for being here from the start.** Manage your plan at /billing on the web; iOS users can tap Settings → Subscribe on the web until Apple in-app purchase lands in a future release.
The Home tab is now coaching-first. Instead of long paragraphs of training summary and year-over-year prose, you get a one-sentence headline from your AI coach, three short cards calling out what's working, the caution to watch, and your focus for the week. Last night's recovery (HRV, sleep, body battery / Oura readiness, resting heart rate) sits right there too, with a pill that flags when your HRV is below your 7-day baseline. There's a countdown chip for your next dated goal so your A race is always one glance away, and recent activities are now a horizontal strip. The full briefing and full year-over-year are still one tap away if you want the depth.
Workout evaluations and the AI coach are now aware of the next two weeks of planned workouts on your schedule. Before this, the evaluator would sometimes suggest a session for tomorrow that contradicted what you'd already planned — sounding like it didn't know your week. Now it acknowledges what's scheduled when recommending what's next, while still critiquing the plan when the actual work performed warrants a change. The plan stays a working hypothesis, not gospel.
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.
