What AI generates the thumbnails?

Thumbnails are generated by DALL-E 3 from OpenAI — the same model behind ChatGPT's image generation.

What size are the generated thumbnails?

Thumbnails are generated at 1792×1024 pixels — YouTube's recommended widescreen ratio.

How many thumbnails can I generate per day?

All plans: 5 thumbnails per day. This ensures high-quality generation without overload.

Can I add text to the thumbnail?

Yes. Include the text you want in your description prompt (e.g. "add bold text saying 10X RETURNS") and the AI incorporates it.

Can I regenerate if I do not like the output?

Yes. Each generation is independent. Refine your prompt and generate again — each attempt uses thumbnail credits.
