Image AI

Create Thumbnails That Get Clicks

Make YouTube thumbnails with AI: build one from your footage or a description, refine it in plain English, and download a 1280x720 PNG we never stamp a logo on.

Try asking

Before someone watches the video, they judge the thumbnail. That tiny image decides whether the upload earns a click or disappears in the feed.

Chat Octopus turns thumbnail creation into a conversation. Start from your footage: "use the reaction at 4:10 as the base." Or start from nothing: "create a thumbnail with a dark blue background, my face on the left, and bold white text saying 'The Real Cost'." Either way, you go from idea to image in one prompt.

Refine it through follow-ups. "Make the text bigger." "Move my face to the right." "Add a subtle glow behind the text." "Try a version with a red background instead." Each adjustment builds on the last. No layers panel, no masking, no export settings.

YouTubers use this for every upload because speed matters when you publish weekly. Course creators use it for lesson thumbnails. Podcasters use it for episode art. Ask for a set and each option comes back with one sentence on which hook it is playing, so you can argue with a specific choice instead of asking for something better.

Need multiple options? Ask Chat Octopus to generate three variations so you can pick the best one or run an A/B test.

Frequently asked questions

Yes. Upload a video and frames get sampled across it and read, so a usable one can be picked out. If you already know the moment you want, name the time and that exact frame gets pulled.

1280x720 by default, the standard YouTube thumbnail, delivered as a PNG. Ask for another size or a different crop and it gets resized to that.

Yes, though the words are drawn into the picture rather than laid over it as an editable layer. Say what the text should be and how it should sit, then read it on the result before you publish: drawn letters can double or lose an ending, and the fix is another pass.

Yes. Ask for two or three variations with different layouts, color schemes, or text options. Good for A/B testing or picking the strongest option.
