What AI Form Filler does

Filling a PDF form means typing your details into its fields and saving the result. Wispdf's AI form filler keeps your details in a profile that is encrypted on your device. The AI is sent only the form's field labels, never your values, and works out which detail belongs where. Your values are then filled in on your device, and you review every field before saving.

What's included

Labels only

The AI sees field labels such as Last name or ZIP code, and never the values you fill in.

Encrypted profile

Your details are saved once, in a profile that is encrypted on your device.

Filled on your device

The AI decides which detail goes where. Your values are then filled in on your device.

You check every field

You review each filled field before the form is saved, and can change any of them.

Where your file goes

The AI form filler sends the text of the form's field labels, not the file and never your values, and that text is never used to train models. Your profile stays encrypted on your device, chats without an account are deleted after 24 hours, and account holders choose how long theirs are kept.

Questions about AI Form Filler

How much does the AI form filler cost?

The AI form filler uses 5 AI credits per form. You get 1 AI task a day without an account, and 30 credits a day with a free account, enough for 6 forms. Pro includes 1,500 credits a month, for $8.25 a month billed yearly or $12 billed monthly, with a 7-day free trial and no card.

Does the AI see my personal details?

No. The AI form filler sends only the form's field labels, such as Date of birth or Address, to our AI model. It never sees your values or the file. Your values stay in a profile encrypted on your device and are filled in there. The labels are never used to train models.

How do I set up my profile?

Open the AI form filler and enter the details you use most often. They are saved in a profile that is encrypted on your device. The next time you add a form, the AI matches the form's labels to your profile, and your values are filled in on your device, ready for you to review.

What if a detail ends up in the wrong field?

That can happen, because form labels are sometimes vague or unusual. The AI form filler shows every filled field for you to review before saving, so you can fix anything that looks wrong. Give dates, ID numbers and anything legal or financial an extra look. You stay in charge of what the final form says.

Can I fill PDF forms with AI on my phone?

Yes. The AI form filler works in any modern browser on iPhone, iPad, Android, Windows, Mac, Linux and Chromebook, with no app to install. Your profile is kept encrypted on your device. Reviewing a long form is easier on a bigger screen, but short forms are quick to check on a phone.

What about tax forms like the W-9?

For the W-9, W-4, 1099-NEC and 1099-MISC, try our US Tax Forms tool. It uses the official IRS forms and adds plain-language help next to each field. Its optional AI fill uses your on-device profile and AI credits, and the AI never sees your values there either. Neither tool gives tax advice.
