Use tool ↗About Filly AI
Filly AI reads the fields in a PDF or Word form, matches them against information already saved for a client, and fills the document automatically instead of someone retyping the same details by hand. It also batch-fills the same form for multiple clients at once, adds e-signatures, and includes a small PDF toolbox for merging and splitting files. It's built for people who fill out the same paperwork repeatedly: immigration lawyers, HR staff, accountants, insurance agents and paralegals. Forms are processed through Anthropic's API, which the vendor states does not train on submitted data. The free plan covers 10 forms and 10 fills a month; paid plans start at 19 dollars a month for 20 forms and 100 fills, and the operator is Cyrus Group Kft. in Hungary.

Pros & cons of Filly AI
Filly AI is built around a genuinely repetitive task, refilling the same form for different clients, and the batch mode plus e-signature step cover that workflow end to end. It's narrow by design, though: this is a forms tool, not a general document editor or contract analyzer.
Pros
- Batch-fills the same form for multiple clients at once
- Includes e-signature and basic PDF merge/split in the same tool
- Free tier requires no card to try 10 forms
- Operator and country are clearly disclosed (Cyrus Group Kft., Hungary)
Cons
- Free plan's 10 fills a month is thin for daily professional use
- Scope is limited to forms; it is not a general PDF editor or e-signature platform on its own
Best for
- Immigration lawyers and paralegals filing the same forms repeatedly
- HR and insurance staff processing many client forms per week
Not for
- Users needing contract review or legal analysis, not just form filling
- Teams wanting unlimited free usage before committing to a paid plan
Watch out: Confirm which document types count against the monthly 'fills' quota before relying on the free or Solo tier for volume work.
