Connect Gesso to ChatGPT, Claude, Cursor or any agent and ask for a website, a deck or a poster. It builds live on your canvas in real HTML and CSS layers you can drag, restyle and export. Free to try on Mac.
AI can write a whole website now, but what you get back is code or a picture. You can't grab the heading and move it. So I built a canvas that any AI can design on, made of real HTML and CSS, where every layer it makes is yours to change by hand.
Ask for a deck, a website, a poster. Watch it build live, then drag, restyle and export.
Every image in the gallery was made this way, by an agent, on the canvas.
Agents read a built-in style guide before they design (minimal, Swiss, editorial, dark tech, bold, brutalist, playful), so you get something with a point of view instead of the usual generated look.
It's a beta: free to try with 150 agent calls, and the first 100 founding members get a year for $60.
What would help most: tell me what you asked your agent to make, and where it fell short. I'll be here all day replying.
As someone who designs my own app UIs, this is the part of AI design I've been missing — every generator I've tried hands back a flat image or a pile of code I can't really tweak. Being able to grab a layer and actually move it after the agent builds it changes that completely. Curious what export looks like in practice — is it HTML/CSS only, or can it hand off to Figma too? Congrats on the launch!

Who hunted Gesso?
Gesso was hunted by G Andrew Wilson. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.

Hey Product Hunt 👋 I'm Andrew, and I built Gesso.
AI can write a whole website now, but what you get back is code or a picture. You can't grab the heading and move it. So I built a canvas that any AI can design on, made of real HTML and CSS, where every layer it makes is yours to change by hand.
