Why use Formfy's AI Smart Fill?
Filling in PDF forms manually is tedious, especially for repetitive documents with dozens of fields. Formfy's AI Smart Fill tool reads all the form fields in your PDF and intelligently fills them in based on a natural language description you provide.
Whether it's onboarding documents, applications, or registration forms — describe the context once and let the AI handle the rest. The result is a completed PDF ready to sign or submit.
Frequently Asked Questions
How does AI Smart Fill work?
Your PDF's AcroForm fields are extracted, and Claude AI maps the field names and types to values based on your natural language description.
What should I include in my description?
Include the person's name, relevant dates, role, organization, and any other details that match the form's fields. The AI infers which values go where.
What if a field is filled incorrectly?
Download the filled PDF and use the regular Fill PDF tool to manually correct any fields that were not filled correctly.
Does the PDF need existing form fields?
Yes. The PDF must have AcroForm fields. If your PDF does not have fields, use the PDF to Fillable Form tool first.
