Mac has it as well, but it's very slow and has poor accuracy.

Hey HN,
I built Dictator because I wanted a lightweight, highly controllable voice-to-text tool for macOS that uses my own OpenAI API key instead of a monthly subscription service.
It’s a Lua-based extension for Hammerspoon.
How it works:
Hold Fn (or a custom hotkey) to record.
Release to transcribe.
The text is auto-pasted into your active application (or copied to clipboard).
Technical details & optimizations:
Audio Pipeline: Uses SoX to record directly to FLAC (16kHz mono). This reduces upload size by ~50% compared to WAV, which significantly speeds up the Whisper API response time.
Reliability: Implements a token bucket rate limiter to prevent API abuse and exponential backoff for handling 429/5xx errors gracefully.
Debouncing: I added strict debouncing logic to ignore accidental short taps (<0.4s) and prevent double-triggers.
Security: Your API key is stored locally and sent directly to OpenAI; there is no intermediate server.

I’d love to hear your thoughts on the push-to-talk UX versus a toggle approach, and if anyone has ideas on further reducing latency!

Show HN: I made a free documentation downloader
I needed offline documentation files for my AI models in .md or .txt format, but most of the developer documentation available couldn't be downloaded with a single click.So, I created a downloader and published it for free use, with no strings attached - just download the documentation.Have fun with it!
