Frequently Asked Questions
- Can the AI put text on the thumbnail?
- AI image models render text unreliably, so the tool generates the thumbnail VISUAL and you add the big title text on top afterward — cleanly and editably — in the image editor. That's how the pros do it: a striking image plus crisp, readable text.
- Can I use my own face?
- Yes — drop in a reference photo of yourself and the AI anchors the subject to it, so the thumbnail features you rather than a random person.
- What size are the thumbnails?
- 16:9 (1344×768), the YouTube thumbnail aspect ratio. It scales cleanly to YouTube's 1280×720 requirement and works for any 16:9 platform.
- Is it free?
- Yes — you can generate thumbnails for free with no sign-up. Free users get a limited number of generations per hour; Pro lifts the cap.
