Question 1

Is my personal data safe?

Accepted Answer

Yes. Your profile and the PDF stay in your browser. When you autofill, only the form's field labels and the relevant values are sent to the AI model you selected — nothing is stored on our side.

Question 2

Do I need to pay for the AI?

Accepted Answer

No. FormFill uses OpenRouter, which offers free models. Create a free key, pick a free model, and you're set. Paid models are optional for especially tricky forms.

Question 3

What kinds of PDFs work?

Accepted Answer

Interactive AcroForm PDFs get their fields filled directly. Flat or scanned PDFs have no fillable fields, so you place text, images, and your signature by dragging them onto the page, then export.

Question 4

Can I place my signature?

Accepted Answer

Draw it with your mouse or trackpad, or upload an image. Drag it onto any page, scale it to fit, and it is baked into the downloaded PDF.
