Iterative Editing with ThumbAI 2.1

Refine, undo, and version your thumbnails without starting from scratch.

ThumbAI 2.1 lets you take any generated thumbnail and refine it with follow-up prompts.

How it works

Open any thumbnail from your history. Type a change ('make the background red', 'add a shocked face'). The new version is added to the edit chain.

Every edit is versioned. Roll back to any previous version at any time.

Each iteration costs 2 credits, shown as a +2 badge before you confirm.

Create viral thumbnails in seconds using AI. No login required. Perfect for YouTubers who want higher CTR.
