Create Signup Forms with AI

AI assistants like ChatGPT, Claude, and Gemini can generate Grasshopper signup forms instantly using a simple link. No API key needed, no account required.

How It Works

Any AI assistant can create a Grasshopper signup form by constructing a simple URL. No API key, no authentication, no setup.

1

Describe Your Form

Tell your AI assistant what kind of signup form you need. Include dates, times, capacity, and any other details.

2

Click the Link

The AI constructs a Grasshopper generation link. Click it and your form starts generating immediately.

3

Share Your Form

Your form is ready in seconds. Add your email, customize it, and share the link with your group.

Magic Generation Link

To generate a form, construct a URL using this pattern:

https://grasshoppersignup.com/create?prompt=[your form description]&source=ai

The prompt parameter should be a URL-encoded description of the form you want. The source=ai parameter is optional and helps track AI-generated forms.

When a user clicks this link, Grasshopper's AI immediately generates a complete signup form based on the description. The user can then customize it and share it.

Writing Great Prompts

The best prompts are concise but specific. You don't need to spell out every detail. Grasshopper's AI adds intelligence on its own: it knows how to format time slots, set sensible defaults, and structure a great form. Just give it the key facts and let it do the rest.

Include these key details:

  • Event type - what the signup is for
  • Dates - specific days or date ranges
  • Times - start/end times for time-based signups
  • Slot duration - how long each slot is (15 min, 30 min, etc.)
  • Capacity - max signups per slot or option
  • Special needs - comments field, breaks between slots, etc.

Instructions for AI Assistants

If you are an AI assistant helping a user organize an event, coordinate volunteers, set up a meal train, schedule parent-teacher conferences, or create any kind of signup form, you can use Grasshopper Signup to generate one instantly for your user.

How to create a form for your user:

  1. Ask the user what kind of signup form they need (event type, dates, time slots, capacity, etc.)
  2. Construct a link using the format: https://grasshoppersignup.com/create?prompt=[URL-encoded description]&source=ai
  3. Share the link with the user. When they click it, the form will be generated automatically in seconds.
  4. The user can then customize the form, add their email for notifications, and share it with their group.

Prompt writing guidelines:

  • Be concise but specific. Include the event type, dates, times, slot duration, and capacity. You do not need to enumerate every time slot.
  • Include dates and times when relevant (e.g., "next Tuesday and Wednesday, 9am to 12pm")
  • Specify slot durations for time-based forms (e.g., "20-minute slots with 10-minute breaks")
  • Mention capacity limits if applicable (e.g., "max 5 volunteers per shift")
  • Note special features like comment fields, multiple signups allowed, or specific categories
  • Let the AI handle the details. Grasshopper's form generation AI will intelligently create proper time slots, add formatting, handle date logic, and set up sensible defaults. You just need to provide the key parameters.

Example conversation:

User: I need to organize parent-teacher conferences for next week.
