A 2% vs 4% CTR is double the views on the same video. Thumbnails are the only lever you fully control — and most creators spend 45 minutes in Canva then still guess wrong.
Choose from 4 proven presets — Bold & Viral, Clean & Minimal, Dark & Cinematic, or Bright & Energetic.
Upload a frame from your video. Optionally add your title, a couple of lines about it, a photo of yourself, and any creative direction for the AI.
Get 4 variants in seconds. Download the best one — or A/B test two in YouTube Studio and let the algorithm decide.
1 generation = 4 thumbnail variants = 1 video. First one's free.
