Filly AI

Filly AI is a web-based form filler that automates the tedious process of filling out PDFs and Word documents. Instead of manually typing the same information into every form, users upload a blank document — whether it's a government PDF, a contract, or a client intake packet — and the tool extracts every field using AI. It then fills those fields from a saved client profile, so commonly repeated details like names, addresses, and ID numbers appear automatically. The filled form can be exported as a pixel-perfect PDF or sent for e-signature with a single link.

The tool relies on Claude for field extraction, even handling scanned documents via OCR. What makes it stand out is the reusable client profile system: save a client's details once, and they auto-fill across any form. A completeness score shows what information is still missing. The smart autofill color-codes each field by confidence, so you only need to review uncertain entries. It also learns from corrections — if you remap a field or adjust a value, it remembers for next time. Batch fill generates the same form for up to 20 clients at once, downloading them as a single ZIP. For faster template creation, the Pro plan lets you describe a document in plain English and have Filly generate a ready-to-fill template with fields and autofill built in.

Filly AI is built for professionals who handle repetitive paperwork. Immigration lawyers fill visa applications in seconds, freelancers send NDAs and contracts without back-and-forth, and HR managers batch onboard new hires. The free plan includes three forms, five clients, and ten fills per month — enough to test the workflow. For heavier use, paid plans start at $19/month and scale up to team seats and custom domains.
