AI Thumbnail Improver

Just critique it

Give us the thumbnail you want fixed. The AI critic scores it first — you pick which of its fixes to apply, then it generates an improved version of your own image.

The analysis uses 1 of today's critiques

How it works

  1. Upload your thumbnail or paste a link to the video it belongs to — the AI critic analyzes it the way viewers meet it: tiny, in a crowded feed, for a fraction of a second.
  2. Pick the suggested fixes. The critique returns up to three concrete changes; you choose which ones to apply, and can add one request of your own.
  3. Generate an improved version. AI edits your actual image at 1280×720 — same subject, same face, fixed thumbnail — and you download it or compare it against the original.

Improving needs an account: 10 free improves a day. The analysis step is a regular AI critique and spends one of your daily critiques, so you always see the score and the reasoning behind every fix before anything is generated.
