Sample head-to-head
One video · two covers · traffic split in the wild
AWinner
BThe cover you almost skipped might be the one that scales.
Evidence in, guesswork out
Score before you ship
Legibility, focus, and clutter in seconds — before the upload.
Thumbnail + title together
CTR is a pair. Test the combo, not isolated assets.
Traffic follows winners
Live A/B with smart allocation — more views on what works.
Private by default
Your channels and tests stay yours. Opt-in only for training.
Validation, not another tool pile
One flow from “which cover?” to “we know which one works” — AI first, real channel tests when you’re ready.
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.
From draft to decision
Fast pre-publish signals when you need speed. Real A/B truth when you need certainty.
Bring a candidate
Upload a draft cover (title optional) or link a video from your connected channel.
Stress-test it
Get an explainable AI diagnosis, rank options in a feed context, or run automated rotation live.
Lock the winner
Ship with confidence, re-test older uploads, and keep a trail of what moved your CTR.
