The Thumbnail EngineBehind Top Creators

THUMBEAST is built specifically for YouTube thumbnails. Every feature—facial expressions, composition, color psychology, prompt enhancement—is designed around what makes people click. Generic AI tools create art. We create clicks.

Yes. Upload up to 8 reference photos of your face. Our AI maintains your facial features across unlimited scenarios—shocked reactions, celebrations, dramatic poses. Your audience will always recognize you.

Plans start at $8.25/month (Starter, billed annually at $99/year). When you sign up you get 1 free thumbnail generation to try the product — no credit card required. After that, pick a plan when you need more.

About 30 seconds. Describe what you want in a text prompt and the AI handles the rest—composition, lighting, expressions, everything. You can also use the prompt enhancer to optimize your idea automatically.

Yes. You own everything you generate. Full commercial rights, no attribution required. Use them on YouTube, social media, merchandise, ads—anywhere. We claim no ownership of your output.

No. YouTube's monetization policy targets misleading content and AI-generated videos that imitate real people—not thumbnail design tools. Thousands of creators use AI design tools (Photoshop's Generative Fill, Canva, Adobe Firefly) without issue. THUMBEAST creates the thumbnail; the content is still yours.

Your face references are stored encrypted in our private object storage and only used to generate your thumbnails. We never share, sell, or train external models on them. You can delete every reference photo at any time from your account settings—deletion is permanent and immediate.

On signup you get 1 free thumbnail generation to test the product, no credit card required. After subscribing, you can cancel anytime to stop future billing. We don't offer prorated refunds for partial months, but you keep full access until the end of your current period.

Yes. No contracts, no cancellation fees. Cancel directly from your billing settings and keep access until the end of your current billing period.

Your generated thumbnails stay in your gallery permanently—cancellation doesn't delete them. You'll just lose access to generating new ones. If you re-subscribe later, your face references, gallery, and settings are exactly as you left them. To fully delete your data, request account deletion from settings.
