Best voice-to-text for coding & AI prompts

Long AI prompts are a great use case for voice: you can speak a detailed instruction in a third of the time it takes to type it. For dictating into Cursor, Claude Code, Terminal, or any editor on Mac, the best picks are Relay (free, on-device, app-aware rewrite), Aqua Voice (best technical accuracy, cloud), and Talon (full hands-free control, steep learning curve).

If you write prompts to AI coding tools all day, you're typing paragraphs that you could say out loud in seconds. Dictation is a genuine speed-up here: in a 2016 Stanford and Baidu study (Ruan et al.), speech input ran at 153 words per minute against 52 typed, about 2.9 times faster. But code and prompts have specific needs: technical vocabulary, working inside any app, and ideally formatting that suits a prompt rather than an email.

The picks

Relay, best free, app-aware option

Relay's ⌘3 rewrite mode tunes output to the app you're in, so a prompt dictated into Cursor or Claude Code comes out as a clean instruction, not a rambling transcript. On-device, works in every app and terminal, free during beta. Good general technical accuracy via Whisper; for extreme jargon density, see Aqua. Why it fits: you dictate prompts into many tools, and Relay works in all of them without sending audio to the cloud.

Aqua Voice, best technical accuracy (cloud)

Its cloud model is specifically tuned for technical and coding vocabulary and is widely cited as the most accurate on variable names and jargon. About $8/mo, requires internet, audio goes to the cloud. Pick it if accuracy on dense technical terms beats privacy for you.

Superwhisper, best customizable, on-device

Custom prompt modes mean you can build a "coding prompt" mode that formats output how you like. On-device, free tier or $8.49/mo. Pick it if you want to tailor the output and don't mind setup.

Talon, best for full hands-free coding

The serious accessibility/RSI choice: voice commands, noise control, eye tracking and Python scripting to fully replace keyboard and mouse, not just dictate text. Free core; $25/mo beta. Pick it if you need to code entirely hands-free and will climb a steep learning curve. For most people who just want to dictate prompts, it's more than you need.

What matters for this use case

If you want to type prompts with your voice, start with Relay (free, on-device, works everywhere). If you need maximum jargon accuracy and accept cloud, add Aqua Voice. If you can't use your hands, Talon is in a class of its own.
