What do you think? …

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.

@melvynxdev nice launch! are the face profiles stored as embeddings?

Nika

Will there be more models for generating images available? (rn, Nano Banana and GPT are available).

BTW, tried one image:

Melvyn

@busmark_w_nika ahaha yes GPT Image 1.5 I think is not completely up, but we have Nano Banana and GPT. Nano Banana does a best job in 99% of the cases so...

Thanks you for the test, you ask to remove the YouTube logo ?

Nika

@melvynxdev To be honest, I didn't ask for removing the logo, I just uploaded images of some random guys and applied the flame template :D

💡 Bright idea

Nice job! Does it work with faces, or can I use other objects as a reference too?

Melvyn

@topfuelauto hey yes, a lot is build for good images references, should add it too : https://thumbfa.st/docs/images-guide

This resonates a lot. Thumbnails are one of those “high-leverage but time-sucking” tasks. If you’ve already proven performance uplift on your own channel, that’s a strong founder signal. Curious to see how well it generalizes across niches.

Melvyn

@sahil_jagtap2 Yes, already getting crazy results on my channel, she blew up so fast. Thanks you for you're message.

Azaz

Congrats on the launch!, btw how is it different from the general models ?

@cynilv UI / UX experience is the value here, i take only 20% margin on the API Price

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

Melvyn

@huseyinsari yes exactly you understand everything 🚀

This is interesting — especially the “iterate until it feels right” angle. Thumbnail design is one of those things where speed + feedback matters more than perfection. Curious how you’re handling style consistency across a channel (or if that’s on the roadmap). Nice execution 👏

Melvyn

@shemith_mohanan thanks you very much 🚀
