Drop in your face, grab inspiration from any YouTube thumbnail, describe your vision—AI generates it instantly. Iterate until perfect. 100x cheaper than a thumbnail designer.
I run a 40K+ YouTube channel. I used to spend 30–45 min per thumbnail in Canva.
Then I tried AI. My AI thumbnails started outperforming my handmade ones—consistently.
So I built the tool I wish I had: drop your face, pick an inspiration, describe what you want. Done in seconds.
That's Thumbfa.st.
Great tool this solves a real pain for creators fast consistent thumbnails + cheap pricing is a huge win reels/shorts presets and topic based style suggestions would make it even stronger
@cynilv UI / UX experience is the value here, i take only 20% margin on the API Price

I love the idea of just grabbing inspiration from any YouTube thumbnail and letting AI do the rest. I wonder how much I can actually customize like, can I tell the AI to change just the text or the lighting after it generates the first version?
@theaxx yes you can ask anything, Nano Banana is able to edit it really cleanly

Wasn’t expecting it. The first generation wasn’t what I wanted precisely but then I added “make sure to use my face” to the prompt and a beautiful thumbnail was generated.

@melvynxdev nice launch! are the face profiles stored as embeddings?
Nice job! Does it work with faces, or can I use other objects as a reference too?

@tied_sergosu Hey, sadly, random time, the AI is not able to use the right face, but as you can see, it's nice sometimes.
