How does the AI know what information to put in each field?

By providing the AI with a reference profile or data context, it intelligently maps your provided information (like name, address, or company details) to the corresponding semantic fields in the PDF form.

Does it work with scanned, non-interactive PDF forms?

Yes, our tool incorporates OCR technology to identify field boundaries and text labels even on flat, non-fillable scanned documents, overlaying the text accurately.

Can it fill out complex tax or government forms?

While it handles standard fields (names, dates, addresses) exceptionally well, complex forms requiring calculations or conditional logic should be carefully reviewed after the AI populates them.
