Feature ideas
- 1CTR analyzerPredicts clickability from contrast, faces, text, and composition.
- 2Fix-this modeAI generates improved thumbnail variations on the spot.
- 3Competitor compareStacks your thumbnail against top-performing videos in the niche.
First-week milestone
Upload → get a brutal 1-paragraph roast + a numeric CTR estimate. Variations and competitor compare come next.
Distribution playbook
- Twitter/X: post the brutal roasts (with creator permission). Each one is shareable bait.
- Sponsor YouTube creator-tools roundups (TubeBuddy / VidIQ audiences).
- Free-tier hook: 'roast my thumbnail' embed widget creators put on their channel page.
Guardrails & risks
- CTR predictions are vibes-based — frame them as 'opinion, not science', or you'll get roasted yourself.
- Image-gen variations need a 'don't infringe on a face I didn't upload' rule.
- Don't undercut the user's brand — let them lock fonts, colors, and face placement.
Validation signal
Conversion from free roast to second roast within 7 days. Creators churn fast — repeat use in week one is the signal.
Why It Works
Every creator wants more clicks, immediately.
