I've been using speech-to-text tools every day now especially for dictating detailed prompts to LLMs and coding agents. I personally use VoiceInk which is open-source.
I tried to look for what other solutions are available and I've collected all the best open-source ones in this awesome-style GitHub repo. Hope you find something that works for you!
