About this app

Before anyone watches your video, they see one image: the thumbnail.

Making a good one usually takes a laptop, a design tool and an hour you do not have. ThumbSnap AI is an AI thumbnail maker for your phone: describe your video, pick a niche or a visual style, and the AI generates a thumbnail you can finish in the app and export at exactly the size YouTube uses.

HOW IT WORKS IN 3 STEPS
1. Describe your video. Type a prompt, or pick a niche like gaming, vlog or podcast.
2. Generate. The AI thumbnail generator creates your image in seconds, or generate three and let the AI pick the strongest one.
3. Finish and export. Add text, emoji and stickers in the editor, then export at YouTube size.

GENERATE FROM A PROMPT, A NICHE OR A STYLE
- Describe your video in your own words.
- Or start from a Quick style: gaming, vlog, podcast, tech, horror and fitness.
- No idea what look you want? Pick a Visual Style and let the app set the direction.
- Add reference: attach a photo from your gallery or camera, and the AI works from it.
- Stuck on wording? Title ideas suggests the words to put on the image.

THREE OPTIONS, AND THE AI PICKS ONE
Generate three thumbnails and tap Ask AI to pick. The app names the strongest option and explains why, so you are not choosing on gut feeling alone.

AI THUMBNAIL SCORE, OUT OF 10
Every thumbnail gets a score plus concrete tips to improve it. The score is the AI's analysis of readability, contrast and composition. It is not real viewer data, and it cannot tell you how many people will click.

FINISH IT IN THE EDITOR
- Text overlay with named styles, so your words look designed in one tap.
- Emoji and stickers.
- Adjust, to fix brightness, contrast and color.
- Background removal, to cut your subject out of a photo.
- Face swap, to put a face you choose into a generated thumbnail.
- Everything you make is kept in your library in the app, so you can come back to it later.

MADE ON YOUR PHONE, SIZED FOR YOUTUBE
No laptop and no design software. Exports come out at YouTube's exact thumbnail size, straight from the app. The perfect size for YouTube, from your phone, no need to edit.
