What is Filly AI?
Filly AI extracts fields from PDF and Word forms and auto-fills them from reusable client profiles, learning field corrections so repeat fills come out right. Includes 18 pre-mapped US government forms, batch fill, CSV filling, no-login e-sign and a PDF toolbox.
Filly AI is a form-filling service built around a simple premise: the same client details get retyped onto the same forms far too often. Upload a blank PDF or DOCX, and the product uses Claude to identify each field, its type, and the data it expects, including on scanned documents through OCR. Pick a client from your saved profiles and matching fields populate themselves, colour coded by confidence so attention goes only to the entries that need it. Filled PDFs export as an overlay on the original layout, so the document looks like the source rather than a rebuilt copy. The feature that separates Filly from generic autofill is memory. Any correction to a value or field mapping is stored against that specific form, so the next fill for a different client comes out correctly placed without remapping. Client profiles carry a completeness score that flags missing details before a fill starts. Beyond single documents, the tool batch fills one form for up to 20 saved clients and bundles the results as a ZIP, or fills from a CSV where each row becomes a document. Sharing is handled with a no-login signing link, and the app sends a notification when the recipient signs. The library is aimed at professionals with recurring paperwork: immigration and tax practitioners, HR teams running onboarding, accountants, and freelancers sending NDAs or contracts. 18 US government forms (IRS, USCIS, SSA) are pre-mapped, alongside templates for invoices, offer letters, service agreements and a CV. A PDF toolbox covers merge, split, rotate, redact and image-to-PDF work, plus an AI tool that reorganises pages from a plain-English request. Against manual filling or basic PDF editors, Filly trades setup time for repeat speed. Weaker fits are one-off documents, since the learning model pays off only on forms you reuse, and teams needing deep accounting or HRIS sync will find the scope narrower than a document management suite.
How do you use Filly AI?
1Create an account and claim your free credits
Sign up to receive 10 free credits and access the free forever plan. No credit card is required to start.2Pick a template or upload your own form
Browse ready-made templates such as a mutual NDA or invoice, or drop in a blank PDF or DOCX up to 4MB. Files stay private and are not used for AI training.3Or start from an official US form
Choose from the 18 pre-mapped government forms, for example W-9 or I-9, and skip field upload entirely since the mapping is already built.4Build the client profile
Save the client once with the details the form needs. The completeness score shows what is still missing before you attempt a fill.5Review the colour-coded fill and correct anything
Filly drafts every field and marks confidence levels. Fix a value or remap a field once; the correction is stored against that form for future fills.6Export, batch fill or send for signature
Download a pixel-perfect PDF, run the form for many clients at once, or share a no-login signing link and get notified when it is signed.
Pros and cons
Pros
- Learns per-form field mapping, so corrections persist across every future fill of that documentAI
- 18 pre-mapped IRS, USCIS and SSA forms plus ready-made contract and HR templatesAI

Cons
- Learning is tied to individual forms, so fixing every field still has to be done once per document typeAI
- Free tier caps at 10 forms, 5 clients and 10 fills monthly, tight for anything beyond evaluationAI
- Batch limits are modest: 5 clients on Solo and 20 on Pro, which constrains high-volume onboardingAI
