Profile

Hi HN, I'm the solo developer behind Ratschn.I type a lot and got extremely frustrated with the current state of Mac dictation tools. Most of them are either heavy Electron wrappers, rely on cloud APIs (a privacy nightmare), or force you into a SaaS subscription for a tool that essentially runs on your own hardware. I wanted something that feels native, respects system resources, and runs entirely offline without forced subscriptions.The stack is Rust, Tauri, and whisper.cpp. Here are the design decisions I made:Model Size vs. Accuracy: Instead of using the smallest possible model just to claim a tiny footprint, the app downloads a ~490MB multi-language Whisper model locally on the first run

The company sits in the show hn launch segment, where it competes on its core product or service.

It is recorded at the Show HN launch stage.
