Voice assistant for Cursor on Mac: explain errors, dictate prompts, write commit messages
Lazur is a voice assistant for Cursor on your Mac. Hold ⌥ ⌘ to ask what the error on screen means, or hold fn to talk a long prompt into the agent box. It works next to Cursor's own AI.
You say“what does this error mean?”
Lazur · explains what's on screenYour useEffect returns a promise. Effects must return nothing or a cleanup function. Move the async call inside.
Quick answer
- Hold ⌥ ⌘ on a red stack trace and ask “what does this mean?”. Lazur reads it and answers out loud.
- Hold fn in Cursor's chat and say the whole prompt. Long context is easier to say than type.
- Say “write a commit message for this” with the diff open, and it appears at your cursor.

Why talk to your editor
Prompts for coding agents are getting longer. The useful ones carry context: what you tried, what must not change, which test fails. Saying that takes seconds. Typing it is where people cut corners.
Lazur and Cursor's own AI
Cursor's agent edits code. Lazur does not. Lazur is the voice layer around it: it explains what is on screen, types your prompts, and handles the small stuff like timers and doc searches without leaving the editor.
