Filly AI vs. pdfFiller
pdfFiller is a broad PDF editing and management suite — edit, annotate, sign, and manage documents — with form-filling as one part of a large toolset.
Quick answer
Filly AI is a focused pdfFiller alternative for auto-filling forms. Instead of a broad PDF editor, Filly reads a form with AI and fills it from saved client profiles, then batch-fills across clients and collects e-signatures — a lighter, purpose-built workflow for people who mainly need forms filled.
Where pdfFiller is strong
pdfFiller is a mature, full-featured PDF suite. If you need general editing, annotation, and document management in one place, it covers a lot of ground.

Why teams switch to Filly
Purpose-built, not a Swiss-army suite
pdfFiller does everything; Filly does one thing well — read a form and fill it from data you've saved. Less to learn, faster to a finished document.
Client profiles do the typing
Rather than editing each PDF by hand, save a client once and Filly auto-fills every field it recognizes, color-coded by confidence.
Batch fill across clients
Produce the same form for up to 20 clients in a single run — a workflow a general editor isn't built around.
Free plan, simple pricing
Start free with no credit card; paid plans from $19/month, so you're not buying a whole editing suite to fill forms.
Try Filly free — no card
Fill your first forms today. 3 forms, 5 clients, 10 fills a month on the free plan.
