I'm using Wispr flow, but I've also tried Superwhisper. Both are fine. I have a convenient hotkey to start/end recording with one hand. Having it just need one hand is nice. I'm using this with the Claude Code vscode extension in Cursor. If you go down this route, the Claude Code instance should be moved into a separate window outside your main editor or else it'll flicker a lot

another option is MacWhisper if someone is on macOS and doesn't want to pay for subscription (just one time payment) - pretty much all of those apps these days use paraspeech from NVIDIA which is the fastest and the best open source model that can run on edge devices.

Also haven't tried but on latest MacOS 26 apple updated their STT models so their build in voice dictation maybe is good enough.
