Show HN: FormFill – Easily Fill PDF Forms Using Anthropic's Computer Use API (opens in new tab)

Hi HN!

I created FormFill, a CLI tool that uses the Claude Computer Use API to automate filling out PDF forms without needing a full virtual machine environment.

You can use it like this: formfill path/to/form.pdf -s "Name: John Smith, Age: 30, Occupation: Engineer"

The Claude Computer Use API is still very new, and I’m hoping FormFill will inspire creative approaches to using it for UI automation. There’s a lot of potential for tools that don’t need full VM control but can still interact with document and UI elements.
