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.
Sales inquiry forms first. Most "contact sales" forms ask the same five things my agent already knows. When an agent submits, does the receiving side see it came from an agent, and can they choose to only accept human submissions on some forms?
@lancelot_d_souza1 Sales forms are exactly where I'd start too. On purpose, no: an agent filling a form for its person is that person answering, so there's no human-only switch. I believe agents will become as reliable as humans, if not more, in the long run.
Can forms connect to some kind of CRM tool?
@mertcansaglam Yes. Every Cube form can send each answer to a webhook (and email or Slack), so it drops into HubSpot, Attio or any CRM through Zapier/Make or your own endpoint. Native CRM connectors are next: which one do you use? That's the one I'll build first.
@bonan_kou Thank you, we are trying to incorporate hubspot into our workflow since we got sweet deals in an accelerator. We bought hubspot for cheap now we need a way to get most out of it
@mertcansaglam Perfect, HubSpot it is. I can set it up end to end for you, free, and you'd be the first user of the native HubSpot connector. :) Let me know if you are interested: hello@usecube.io
@bonan_kou yup, sent a mail
Waitlists are a good use case for this. Filling out the same details over and over gets old fast.
@robert_smith52 That’s a great use case. Going to add more options for people to embed cube forms on their website and more agent-friendly components to the project soon.
Being able to jump in and fix an answer without starting over makes a lot of sense.
@vhim_jana Thanks Vhim! And yeah, agents are great at filling out the boring part of a form but human intervention is still required for edge cases.
the PH form anecdote is a good pitch, but it also points at the thing I'd worry about on the receiving end. "no browser, no CAPTCHA" is great for the agent filling the form, but a waitlist or sign-up form is normally the thing CAPTCHA exists to protect, if any agent can hit it over plain HTTP with no human in the loop, what stops the same mechanism from being used to submit a form a thousand times instead of once? is there rate limiting or some form of identity on the submitting agent, or is the trust model "whoever has the link is allowed to use it, as many times as they want"?
@galdayan Fair worry. It's not "unlimited for whoever has the link": submissions are rate-limited per sender, and invalid answers bounce back with a fix-it message. What's still missing is identity. Next step: agents sign their requests (HTTP Message Signatures, the standard behind Cloudflare's Web Bot Auth), so a form can give verified agents room and throttle anonymous ones. Will keep improving!
Bonan, the shared form link for people and agents caught my eye. Being able to inspect and change what an agent filled in feels like a useful part of the handoff. Congrats on the launch!
@oleksii_sekundant Thanks Oleksii! I really believe we need a new kind of internet, built with components that work for both agents and humans, unlike traditional forms like the one we all have to go through to post on PH. If you try it with your own agent, I'd love to hear where it stumbles.
