Voice to text for developers, on your Mac

Most of a developer's typing is not code: it is prompts, PRs, reviews, tickets and Slack. Hold Fn and say it instead. It runs on your Mac, in 97 languages, and learns the names in your stack.

$2.99 once on the Mac App Store. Apple Silicon, macOS 26 Tahoe.

Where developers use it

Anything that is mostly words. Paste it with ⌘V wherever you are.

Prompts for AI agents
Brief Cursor, Claude Code or Codex in full sentences, with the context you would otherwise skip.
PR descriptions
Talk through what changed and why while the diff is in front of you.
Code review comments
Explain the concern properly instead of leaving a terse “nit”.
Tickets and bug reports
Steps to reproduce, expected and actual, said in one go.
Docs and READMEs
Draft the explanation out loud, then tidy it.
Slack and standups
Quick updates without leaving the editor for long.

Learns your stack

Service names, libraries, teammates and customers. Correct a misheard word once and the dictionary keeps it, so “cooper netties” becomes Kubernetes for good.

Refactor the upload handler so retries back off and the progress bar never jumps.
