Create forms with AI

Describe the form you need in a sentence and Vellform builds the whole structure — questions, field types, pages and a thank-you screen — ready to edit.

  • Every question, option and label is editable the moment it lands
  • Field types are chosen to match what you asked for, not guessed
  • Review and ending pages are added where a form needs them
Generated in one run

“Create a customer feedback form with 8 questions and a 1–5 rating.”

  • How would you rate us overall?Rating · 1–5
  • What nearly stopped you buying?Long text
  • Which features do you use most?Multi select · 6
  • Can we follow up by email?Yes / No

+ 4 more, a review page and a thank-you screen.

AI form editing

Edit your form in plain English

Don't rebuild a form by hand to change it. Ask for a field, a page or a rule and the AI edits the form you already have, leaving everything else exactly where it was.

  • It edits your existing form, never a regenerated copy
  • Ask in your own words — there is no prompt syntax to learn
  • Your theme, logic and copy stay untouched unless you ask
An edit, start to finish
You

“Add a budget question after company size.”

Vellform
  • Read 12 fields across 3 pages
  • Added “Budget range” after “Company size”
  • Left your theme and logic untouched
Not what you meant?↺ Undo this edit
Verified & reversible

AI that shows its work

Vellform reads your form before it changes anything, verifies the result afterwards, and puts every AI edit in the same undo history as your own work.

  • A plain-language summary of what changed, every time
  • The AI edits typed data, never code — it cannot emit CSS or a script
  • One undo reverses a whole AI edit, the same as a manual one

Forms that adapt to every answer

Show the right questions to the right people. Branch on any answer, skip pages that do not apply, and walk a respondent's path end to end before you publish.

  • Rules sit on the connection they control, not in a menu
  • Branches highlight on the map as you set them
  • Route to different endings, pages or queues

Multi-page forms

Simple forms, or multi-step flows

Break a long form into pages people will actually finish. Every page has a kind, and the kind decides how it behaves for the respondent.

  • A Review page shows the answers back before submitting
  • An Ending page closes the run with your own message
  • Progress is saved as they go, so a long form survives a closed tab

Collect and manage form responses

Every submission lands in an inbox inside your workspace. Search it, open a single answer in full, switch to a table, and export when you need the data somewhere else.

  • Partial submissions are kept, so you see who dropped off and where
  • Export to CSV whenever you want — it is your data
  • Choose how long responses are kept, or keep them forever
