Hi HN,

I built this because I had to process a large number of local files with an AI and got tired of the endless copy-pasting.

FlatGem is a simple, open-source desktop tool that connects the Gemini API to your local file system. You set one system prompt, point it to your input/output folders, and it processes everything in bulk.

It's completely free, with no ads or tracking. This is a passion project, I'm not trying to build a business out of it. Just wanted to solve a problem that was annoying me.

The code is on GitHub and I'd appreciate any feedback you have.
