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.
