Features
Everything you need, nothing you don't.
Thumbly is laser-focused on one job: turning your video idea into scroll-stopping thumbnails. We don't do retention curves, consultants, or shorts editors. Just thumbnails, done well.
Upload your face
Drop in a reference photo of yourself or your brand and AI puts you on the thumbnail — no Photoshop skills needed.
Style presets
Gaming, vlog, podcast, MrBeast-style — pick a style and the prompt is tuned for the look that wins clicks in your niche.
1, 2, or 4 variations
Generate multiple options per click and run your own A/B test in YouTube Studio.
Native 1280×720
Every output is sized exactly to YouTube's spec. No manual cropping, no exports going off-center.
Brand-safe moderation
Every prompt runs through OpenAI's moderation API plus a public-figure blocklist before a credit is spent.
Credits never expire

FAQ
Frequently asked questions
Which AI model powers Thumbly?+
We use OpenAI's latest image generation model (gpt-image-2). It supports image inputs, so we can use your reference photo as a face or brand reference.
What if I don't like the output?+
If a generation fails for technical reasons, your credits are refunded automatically. If you just don't like the style, we recommend tweaking your prompt or trying a different preset — every regeneration is a fresh credit.
Can I use these thumbnails commercially?+
Yes. AI-generated images from Thumbly are yours to use on YouTube, social, ads, anywhere. We don't claim copyright.
Can I use someone else's face?+
Reference images should be of yourself, your team, or assets you own the rights to. We block prompts naming public figures and our moderation layer rejects misuse.
Do you accept NSFW content?+
No. All prompts run through OpenAI's moderation API. NSFW, hateful, or violent prompts are rejected before a credit is spent.
What's your refund policy?+
Unused credits can be refunded within 7 days of purchase. Email support@thumbly.app and we'll process it.
