Frequently Asked Questions

Everything you need to know to get started

Getting started

What is ThumbSketch AI?

ThumbSketch AI turns a rough sketch or a photo into a finished YouTube thumbnail in seconds. Draw your layout or paste your facecam, and get a polished 1280×720 thumbnail ready to upload. Then fine-tune it by describing one change in a sentence.

How does it work?

Draw a quick sketch in the editor or paste a photo. Optionally add a prompt, or your YouTube video link for context. Generate, and your thumbnail is ready in seconds. Want to change something? Describe it in one sentence and only that part changes.

Who is ThumbSketch AI for?

YouTube creators who want great thumbnails without spending hours in Photoshop or Canva, especially solo and growing channels. No design skills needed: if you can sketch boxes and stick figures, you can use it. You must be 18 or older.

Why choose ThumbSketch AI over Gemini, Midjourney or ChatGPT's image generation?

Those are great general-purpose tools. ThumbSketch AI is built just for YouTube thumbnails, and uses Google's Gemini under the hood:

Start from a sketch, not a long prompt. Your layout is the instructions.
Tuned for thumbnails: it keeps your layout and your face, and never adds text unless you ask.
YouTube-ready: 1280×720 JPEG, well under YouTube's 2 MB limit.
Edit with one sentence. Every version is saved, and restoring one is free.
All your thumbnails in one place.

Using ThumbSketch AI

What's the difference between AI generations and AI edits?

An AI generation creates a new thumbnail from your sketch, or recreates it from the sketch after you change the prompt. An AI edit changes one thing on a thumbnail you already have, like "make the text white", and keeps everything else. Each uses 1 credit, and failed ones are refunded automatically. Every edit is saved as a version, and restoring an earlier version is free.

What if I don't like the result?

A new generation, a regeneration after you change the prompt, a retry, or an edit uses 1 credit. Restoring an earlier version is free. Failed generations and edits are refunded automatically.

Does ThumbSketch AI work on mobile?

Yes. ThumbSketch AI works in your phone's browser: sketch, paste a photo, generate, edit and download. There's nothing to download from an app store, and you can add it to your home screen to open it like an app.

Do I need to connect my YouTube channel?

No. Download your thumbnail and upload it in YouTube Studio as usual. You can add a video link when you create a thumbnail to give the AI context, but that doesn't require connecting your channel.

What formats do the thumbnails come in?

New thumbnails are JPEG images at 1280×720 pixels (16:9), YouTube's recommended size, and well under YouTube's 2 MB limit.

Can I use the thumbnails on other platforms?

Yes. You keep ownership of your sketches, prompts and thumbnails (see our Terms of Service), so you can use them on YouTube and anywhere else: other video platforms, social posts, your website. They're 16:9, so you may want to crop them for square or vertical formats.
