Filly AI reads any PDF or Word form, extracts every field, and autofills it from a saved client profile in seconds. Review and adjust the placement, export a pixel-perfect document, share a no-login link for review, or collect an e-signature with a full audit trail. Includes built-in IRS forms (W-9, W-4, I-9), 25 ready-made templates, and an AI assistant that answers questions while you fill.
