# Jupiter Signup

> Turn a sentence into a sign-up page that collects payments for classes, events, club dues, and registrations, and runs free when you're not charging.

Jupiter Signup builds and edits the whole form by chat, with no form builder and no schema. It's built for paid sign-ups (classes, events, club dues, registrations, fundraisers) and runs free when you're not charging (RSVP, waitlist, contact). Payment is collected through the creator's own Stripe account for a flat 1% with no monthly fee required; the server recomputes every charge from a trusted price catalog.
