FormFill Ninja – AI-powered Chrome extension automating job application forms

Summary: FormFill Ninja is a Chrome extension that automates filling job application forms by detecting fields and completing them using structured data, rule-based extraction, and AI-generated responses. It reduces repetitive manual entry and speeds up the application process under time pressure.

What it does

It identifies form fields on job application pages and fills them automatically using a hybrid system combining regex, structured data, and large language models. Complex fields like cover letters are generated by AI, while backend APIs run on Cloudflare Workers to optimize performance and token usage.

Who it's for

It is designed for job seekers applying to multiple roles who need to quickly and accurately complete repetitive application forms.

Why it matters

It addresses the inefficiency and error-proneness of repeatedly entering the same information across many job applications.
