What you can build

Jupiter Signup has two halves. The functionality below is what the form actually does and enforces, you get it just by asking. The design is wide open: the page is authored by AI, so the look is whatever you describe.

What it can do

Just say it in chat, these are handled and enforced for you.

Money

Charge for sign-ups

Live

Sell spots as priced items. The server recomputes every charge from the catalog, so the page can never be tampered with to change a price.

e.g. $20 for a single class

Bundles & packages

Live

Offer a bundle that covers several items at a better price. Buying it counts toward each thing it includes (including their capacity), and picking the bundle grays out and zeroes those items so no one double-buys what's already in it.

e.g. $80 for the 5-class pack vs $20 each; pick the pack and the singles lock at $0

Add-ons

Live

Optional extras a person can tack on to their sign-up.

e.g. Add mat rental for $5

Free, paid, or mixed

Live

Payments are optional. A form can charge, be entirely free, or mix paid and free options, and no price or total shows when nothing costs money.

e.g. A free volunteer RSVP with no prices

Bulk discounts

Live

Automatic quantity discounts, applied and re-checked on the server so the total is real.

e.g. 15% off when you book 5 or more

Discount & scholarship codes

Live

A code people type, or a self-serve checkbox like “I'm on a scholarship”, that takes a set percentage off, up to 100% for a free spot. Applied on the page and re-checked on the server, so the real charge always matches.

e.g. A SCHOLAR code (or a scholarship checkbox) that makes the signup free

Real card payments (Stripe)

Live

Take real card payments straight to your own Stripe account via Stripe Connect, with a small platform fee. The buyer pays by card at checkout and the signup is confirmed automatically once the payment clears.

e.g. Take $45 to your connected Stripe account

Collect via Venmo, Cash App, PayPal, Zeffy, Zelle, or cash

Live

No card processing to set up: add your payment handles once, and people pay you directly with a one-tap button right after signing up. You mark who's paid in Results. The money goes straight to you, nothing passes through us.

e.g. “Pay $20 to @your-venmo” after they sign up

A priced form must choose how it collects before it opens

Live

If any option has a price, the server keeps the form closed to sign-ups until the creator picks how they get paid: cards, off-platform, or a deliberate no-charge. This stops a priced form from quietly taking sign-ups it can't collect on, and the button only says “Pay” when money is actually collected.

e.g. A $25 dinner form stays “not open yet” until you choose card or collect-it-yourself
Limits & rules

Capacity limits

Live

Cap how many can take an option. The form shows how many are left, disables the option when it fills, and the server refuses to overbook.

e.g. Max 12 seats, shows “3 left”, then “Sold out”

Pick up to N

Live

Let people choose at most (or at least) a set number from a group of options.

e.g. Pick up to 3 of these 6 workshops

No conflicting picks

Live

Stop people choosing two options that can't go together, like two sessions in the same time slot.

e.g. Can't book both 9am classes

Submission deadline

Live

Close the whole form at a date and time you set. After it passes, the page shows a clear 'sign-ups are closed' notice and the server refuses any new submission.

e.g. Close sign-ups at noon on July 1
What you collect

Custom questions

Live

Ask for whatever you need, short text, email, phone, numbers, dropdowns, or longer paragraphs, and mark any of them required.

e.g. Name, email, t-shirt size, dietary notes

Per-option questions

Live

Attach a question to a specific option, so it's asked only when someone picks that option. Make it required or optional. Put it on every option or just some.

e.g. Pick the t-shirt and it asks your size; required
Automations

Collect a phone number

Live

Add a phone field to the form with one toggle.

e.g. Ask for a mobile number

Confirmation email

Live

After signing up, people can email themselves a confirmation, no setup needed, and nothing is sent unless they ask for it.

e.g. A “you're in” email after an RSVP

Get emailed when someone signs up

Live

You get an email for each new sign-up, with who signed up and what they chose, and replies go straight to them. On by default; turn it off per form for high-volume sign-ups. Paid sign-ups notify once the payment clears.

e.g. An email the moment someone registers for your class

Add to calendar

Live

When a form has a date, the confirmation screen offers one-tap add-to-calendar: a Google Calendar link for each event the person signed up for, plus an .ics download for Apple Calendar or Outlook. Nothing is sent; the responder adds it themselves.

e.g. An “Add to Google Calendar” button after signing up for a dated class

Reminders

Live

Turn it on and everyone who signed up gets a reminder before the event, a day ahead by default, by email and by text (a text goes to anyone who gave a mobile number and opted in). Chat to change the timing or wording, or add another. Needs a date on the form. Send yourself a test to see it first; people can opt out any time, or reply STOP to a text.

e.g. A reminder the day before class

Waitlist when full

Live

Turn it on and once every spot is taken, the form collects a waitlist (name and email) instead of just closing. You see who's waiting in Results and email them yourself when a spot opens. Nobody is auto-added, no spot is held.

e.g. Class sells out, 6 people join the waitlist
Sharing

Share by link

Live

Every form gets its own link to share anywhere.

e.g. Send the link in an email or post

Embed on your site

Live

Grab an embed snippet from your dashboard and paste it into any web page. The form appears inline, submits in place, and the frame auto-resizes. Paid forms hand off to secure checkout in the top window.

e.g. Embed the sign-up on your homepage
Results

Results + ask anything

Live

See every response in a table and ask plain-English questions about them.

e.g. “How many picked the bundle?”

Views & conversion

Live

See how many real people opened your form, the share who signed up, and roughly where views came from. Bots, link previews, and your own visits aren't counted.

e.g. 40 views · 12 sign-ups · 30% · top: Chicago, London

How it looks

The page itself is designed by AI, so there's no template to fit inside. Describe the look and it's built, then tweak it by chatting.

Any layout & copy

Hero, sections, tone, wording, "make it feel like a festival lineup," "warmer copy," "add an FAQ."

Themes & color

Light or dark, with accent colors, flip them instantly under Setup, or just ask.

Your structure

Group options however makes sense, by time, by tier, by location, and rearrange anytime.

On-brand details

Badges, notes, nudges, helper text, ask for the touches that fit your event.

Your logo

Upload your logo under Setup and it shows on your form.

Asked for something we can't do yet? The form tells you honestly instead of pretending, and we log it to decide what to build next.
