Install the Fantastic Forms skill into Claude. Ask for any form in plain English. Claude drafts the schema, publishes it to a 24-hour demo, and hands you a live URL you can share.No API key. No signup. Rate-limited to 3 forms per day.
In plain English. "A restaurant reservation form with party size, date, and dietary notes."
The skill teaches Claude our 50+ field types and conditional-logic grammar so it produces valid JSON on the first shot.
Skill posts the JSON to our public demo endpoint. Two seconds later you have a shareable /f/<id> link.
Two ways: install the skill in Claude and just chat, or hit the endpoint yourself with curl.
Build me a post-purchase NPS survey.
If the score is below 7, ask what went wrong.
If it's 9 or above, ask if they'd share it on social.Claude will call the skill automatically once it's installed.
