Help & FAQ

How to create a form Describe what you need in plain language and the AI builds the whole form. Can I use a GrasshopperSignup link GrasshopperSignup is our sign-up BFF. Paste one of their form links into the builder and we will try to recreate a similar form. How to change your form Every change is made by chatting, there is no manual editor by design. How to charge money for sign-ups Tell the form your prices; the server computes every charge from the catalog. How much does Jupiter Signup cost (fees) Building forms is free; our platform fee is 2% on card payments, with no fee on free forms or money you collect yourself. Why my form says sign-ups aren't open yet, and how to open it A form with a price won't take sign-ups until you choose how to get paid. Pick a method in Setup, Get paid, and it opens right away. How to make a free sign-up or RSVP Forms don't need prices, build a free RSVP, waitlist, or volunteer sign-up. How to limit how many people can sign up Set a capacity so an option shows how many are left and stops when it's full. How to close sign-ups at a deadline Set a date and time and the form stops accepting sign-ups after it, automatically and enforced on the server. How to collect a waitlist on a full form Turn on Waitlist when full in Setup, and once every spot is taken the form collects names and emails so you can notify people when a spot opens. How to see who signed up View every response in a table and ask plain-English questions about them. How to share or embed your form Every form has its own link, and can be embedded on your own website. Where to set up getting paid Connect Stripe or add your payment apps once on the Payments page; every form reuses them. How to use the API or connect an AI assistant Make an API key, then call the REST API or wire your forms into Claude or ChatGPT over MCP. How to sign in (and set a password) Sign in with Google or a magic link; optionally add a password under Account for next time. What fonts can I use Set your form's typography by chatting, or request a font we don't have yet. How to ask a human for help Send a question straight to a person when the FAQs don't cover it.
