About Filly AI
What is Filly AI?
Filly AI is an AI-powered form filler that automatically extracts fields from PDF and Word documents and fills them with your saved client data. It eliminates the repetitive typing of addresses, case numbers, and other details across multiple forms, saving hours per week.
Who is it for?
Filly AI is built for professionals who handle high volumes of forms — legal assistants, HR teams, immigration consultants, and small business owners. It is not designed for casual users who only fill a few forms a year; its value grows with repetition and batch processing.
Key problems it solves
Stop re-typing the same information and re-mapping fields on every new document. Filly remembers your corrections, so once you fix a field, it stays fixed. It also batch-fills forms for up to 20 clients at once, and includes 18 official US government forms (IRS, USCIS, SSA) for instant filling.
Real use cases
- Immigration consultants auto-fill I-9, I-765, and I-864 forms from client profiles.
- HR teams generate offer letters and NDAs for multiple new hires with one click.
- Accountants use W-9 and W-4 templates to onboard clients without re-typing tax IDs and addresses.
Key features
- AI field extraction — Upload a PDF or DOCX, and Claude identifies every field, its type, and needed data, even from scanned documents via OCR.
- Reusable client profiles — Save each client once; their details auto-fill across every form, with completeness scores to flag missing info.
- Smart autofill — Pick a client and watch matching fields fill themselves, color-coded by confidence so you only review what matters.
- Learn from corrections — Remap or nudge a field once; Filly saves it for that form, making future fills exact and instant.
- Batch fill — Generate the same form for up to 20 saved clients at once and download them as a ZIP.
- Fill from spreadsheet — Upload a CSV and get a filled, signable document in under a minute.
- Official US forms built in — Access 18 real IRS, USCIS, and SSA forms, included on every plan, even the free tier.
