Cube forms are made for AI agents. Your agent can create a form and fill one in directly, over MCP or plain HTTP, from Claude Code, ChatGPT, Cursor or any agent. No browser, no CAPTCHA. People can still open the same link and step in anytime: check what the agent filled, change anything, or fill it themselves. Free. Sign-ups, waitlists, bug reports, sales inquiries, any form.
Hi Product Hunt, I'm Bonan.👋
My agent always knows everything a form asks for, but I still end up typing it into a browser myself. So I built Cube: every form is one link. People fill the page; agents read it and submit it directly, no browser.
Fun fact: submitting this launch took me half an hour of Product Hunt's own forms. My agent knew every answer and couldn't fill a single field. That's exactly the gap Cube is for.
Try it without signing up: tell your agent "Fill out this form for me: ui.usecube.io/f/early-access".
It's free and early. I'd love to hear where your agent gets stuck, and which form you'd open to agents first.
