How it works

Frequently Asked Questions

How do I generate a thumbnail?

Simply paste your YouTube video URL into the app. We'll analyze the video and let you generate thumbnails using a prompt, like "make it look dramatic" or "highlight the main character."

Do I need to upload my video?

No upload is needed. Just share your YouTube link, and our system will fetch the video directly to generate the thumbnails.

What kind of prompts can I use?

You can use natural language prompts like "make it more colorful," "add excitement," or "focus on the face." The AI understands a wide range of creative instructions.

Can I edit the thumbnail after it’s generated?

Yes! Once a thumbnail is generated, you can make changes or generate variations (mutants) to explore different creative directions.

Is there a free version?

Unfortunately, no. We currently do not offer a free version of the app. However the first 1000 users will receive a free thumbnail to try out the app.

Can I use the thumbnails on YouTube?

Absolutely. All thumbnails you generate are yours to use. Just download and upload them to your YouTube video settings.
