FormsUI

Turn any PDF into a fillable online form

Upload the PDF you already use — an intake form, an application, a registration — and AI reads it into a structured online form: fields, sections and checkboxes detected for you, not rebuilt by hand. Share one link, and every response comes back written onto your original PDF, ready to file.

How it works

  1. Upload your PDF. AI detects its fields, sections and checkboxes and opens an editable draft.
  2. Review the draft — mark fields required or sensitive, rearrange sections — and publish.
  3. Share the link, email it, or send pre-filled links. Download each submission as a filled PDF.

Responses land on the original, pixel for pixel

Each submission is written back onto your source PDF. Checkboxes are ticked in their printed squares, a second pet or vehicle lands in its own printed row, and a clean summary document comes with every response.

Check the form against its source

Re-scan the original PDF any time. Anything the online form no longer matches comes back as one-click suggestions.

Sensitive fields handled properly

Fields like Social Security and account numbers are masked by default, stored encrypted, and every reveal is audit-logged.

Free to build and share

Building and sharing forms is free. You pay per PDF import and per e-signature from a prepaid wallet, with no subscription and no per-seat pricing.

Frequently asked questions

How do I turn a PDF into a fillable form?

Upload the PDF to FormsUI. AI detects its fields and opens an editable form draft; review it, publish, and share the link. People fill it in online and each response is written back onto the original PDF.

Can people fill in the form on their phone?

Yes. The form is a web page, so anyone with the link can fill it in from a phone, tablet or computer — no PDF reader needed.

Do I get the responses back as PDFs?

Yes. Every submission can be downloaded as your original PDF with the answers filled in, alongside a styled summary document.

Can the form collect a signature?

Yes. Any form can request a legally binding e-signature, and the executed copy comes back automatically.
