Filly AI is a document automation platform that fills in any form in seconds. You upload a PDF or a Word document — even a scanned one, thanks to the built-in OCR — and the AI (Anthropic’s Claude) identifies each field, its type and the data expected. Your clients’ information is saved just once in reusable profiles, then automatically fills in every form, with colour coding by confidence level for a quick review.
The tool includes a library of 16 official US forms (IRS, USCIS, SSA), batch filling for up to 20 clients in a single ZIP, and sharing for e-signature via a link with no account creation. Designed for lawyers, freelancers and HR teams, Filly AI is operated from the EU with encrypted data and GDPR compliance.
What is Filly AI?
The essentials
Filly AI is an AI-powered form filler: upload any PDF or Word document and the tool identifies each field and fills it in automatically from saved client profiles. Built for lawyers, freelancers, HR teams and accountants who fill in the same documents over and over.
Key features
AI field extraction — Claude (Anthropic) reads the document and identifies each field, its type (text, date, amount, signature) and the data expected, including on scanned documents thanks to the built-in OCR.
Reusable client profiles — Save a client once: their information then fills in every form, with a completeness score that flags missing data.
Smart filling — Every value is colour-coded according to the AI’s confidence level, so you only review what matters. Corrections are memorised: the next time the same form is filled in, it is accurate and instant.
Batch filling — Generate the same form for up to 20 clients at once, delivered in a single ZIP.
Sharing and e-signature — Send a private link: the client reviews, corrects and signs from any device, without creating an account.
Official form library — 16 US forms (IRS, USCIS, SSA) pre-mapped to client profiles, included on every plan.
Use cases
Immigration lawyer — Fill in a client’s visa files and USCIS forms in seconds instead of manually copying numbers and addresses page after page.
HR team — Generate onboarding packs for 15 new hires in a single batch, exported as a ZIP ready to file.
Freelancer / consultant — Send a pre-filled NDA or contract with a signature link to every new client, with no email back and forth.
Accountant / notary — Complete recurring tax and administrative forms from existing client records.

Conclusion
Filly AI is aimed at every professional who fills in the same documents on a loop: lawyers, legal counsel, HR, accountants, freelancers. Its real strength is not the one-off filling of a PDF — it is the system of reusable client profiles that turns a recurring chore into a single click. The free plan with no credit card makes it risk-free to try; the Pro plan at $39/month quickly pays for itself from a few dozen forms per month. Credit is due to the publisher for its transparency about the limits of OCR and about European data hosting, which is rare in this segment.
