Lazur is a voice assistant for developers on the Mac. Hold ⌥ ⌘ and ask what the error on screen means, where a setting lives, or for a commit message. Hold fn to talk long prompts into your coding agent.

## Quick answer

- “What does this error mean?” with the stack trace on screen, answered out loud.
- Talk long prompts into Cursor or Claude Code with fn.
- “Write a commit message for this” with the diff open.
- Works in any editor and terminal.

## Where the day goes

- **Errors and unfamiliar code.** Copying a stack trace into a chat window, then explaining what you were doing.
- **Prompts got long.** Good agent prompts carry context. Typing all of it is where people cut corners.
- **Settings you use twice a year.** Signing certificates, build settings, cloud consoles.

## Next to your coding agent, not instead of it

Lazur does not edit your code. Your agent does that. Lazur explains what is on screen, types your prompts by voice and handles the small stuff. See [Lazur in Cursor](https://www.lazur.app/apps/cursor).
