Features
Validation-first tools for YouTube covers — from instant AI readouts to live A/B that actually scales.
Instant AI readout
Legibility, focus, clutter, and message clarity in seconds — before you ever hit publish.
Pair thumbnails with titles
CTR is a combo, not a solo act. Spot when on-image text just restates the title.
Unlimited live variants
Rotate as many covers as you need. Smart allocation pushes traffic to what’s winning.
Metrics you can act on
Clean scores, rankings, and the why — not a mystery dashboard full of noise.
Seen at real feed size
Preview how it looks tiny on mobile, next to competing videos — not full-screen fantasy.
Built for crews
Editors, freelancers, and multi-channel teams can share projects without Slack chaos.
