Limits

Plans

Free includes unlimited events and signups, confirmation emails, calendar files, multi-day events, comments, email updates, automatic reminders 24 hours and 1 hour before, waitlists, up to 10 questions per sheet, any number of co-organizers, themes and fonts, and a QR code. Free sheets show one small ad below the sheet.

Pro is $20 a year or $10 a month: 100 AI covers a month, no ads on any of your sheets, custom branding (your logo and colors on every sheet), and CSV export. Team is $200 a year or $100 a month: everything in Pro, plus unlimited AI covers and no "Made with I'm In!" footer on your sheets.

Share your link, im-in.events/?friend=YOURCODE, shown on your dashboard. A friend who makes their first sheet from it earns you 6 months without ads and $20 toward any plan.

Rate limiting

• Event creation allows 5 requests per IP each hour.
• Signed-in organizers can create 10 events per day; guests can create 2 events per IP each day.
• Hit one and you'll see a message naming the limit (HTTP 429 if you're calling the API). Wait it out, then try again.
• Space out manual reminders. Sending the same email over and over can trip the limits.

Big events

• Big events read best with one slot per role or per time, not one giant slot.
• With Pro, export the whole list to CSV from your dashboard.

Fair use

No scraping and no fake mass signups. Some steps ask for a quick robot check to keep it that way.
