I used to ignore the voice button
When I first set up LacPointer, I treated it purely as a text bar. Option+Space, type a question, get an answer, close it. The little microphone icon was just furniture to me — something I skimmed past.
Then I was eating lunch at my desk one day, hands covered in something I didn't want near my keyboard, and I actually tried it. I pressed Cmd+Shift+V and said "open Slack and go to the engineering channel."
Slack opened. It navigated to the right channel. I just stared at my screen for a second.
That was the moment I stopped ignoring it.
What voice control actually does
This isn't dictation. LacPointer's voice mode uses accessibility APIs on both macOS and Windows to actually manipulate the UI — the same APIs that power screen readers and assistive tools. It can:
- Open apps by name
- Click buttons and UI elements
- Type text into any focused field
- Control media — play, pause, skip, volume
- Navigate within apps
It's not sending keyboard shortcuts and hoping for the best. It's reading the accessibility tree and taking targeted actions. That distinction matters a lot in practice, because it works even when an app doesn't have obvious hotkeys.
How to trigger it
Press Cmd+Shift+V anywhere on your desktop. LacPointer's bar activates in voice mode. Speak your instruction. Done.
You don't need to open the bar with Option+Space first. The voice shortcut is global, so it intercepts from any context — full-screen app, another desktop space, whatever. That matters because half the value of voice control is using it when you're in the middle of something and don't want to context-switch.
Real things I say to it
Here's what I actually use this for day to day, not a curated demo list:
- "Open Terminal and run the dev server" — opens Terminal, types the command, hits enter. Useful when I'm reviewing a PR in the browser and want to test something without losing my place.
- "Pause the music" — obvious, but it works regardless of which player is running. I don't have to remember the media key layout.
- "Open Notion and create a new page called Sprint Notes" — this one is almost cheating. It chains two actions.
- "Type my standup update" — combined with a Persona that has my standup format baked into its system prompt, this drafts and types a standup directly into whatever chat window I have focused.
- "Set volume to 40 percent" — no reaching for the slider.
I'm not doing anything exotic here. These are just small friction points that add up across a workday, and eliminating them with one shortcut is satisfying in a quiet, unglamorous way.
Personas make voice mode significantly better
I touched on this briefly above, but it's worth expanding. LacPointer lets you build custom Personas with a name, a system prompt, and a voice. When you're in voice mode, the active Persona's instructions are baked directly into the session.
This means you can create a Persona specifically tuned for voice control. Give it a system prompt that says something like: "You are a desktop control assistant. When asked to open an app, open it immediately. When asked to type something, type it exactly as given. Be terse — confirm actions in two words or less." Now every voice session with that Persona skips all the AI small talk and just executes.
The built-in Coding Persona is close to this. It's direct, no hand-holding, and doesn't pad its responses. That's my default for voice sessions when I'm in work mode.
Where it runs
Voice control works on macOS (11.0 and up, both Apple Silicon and Intel) and Windows 10/11 64-bit. The macOS implementation uses the Accessibility API, same as VoiceOver. On Windows it uses the UI Automation framework.
One thing worth knowing: on macOS you'll need to grant LacPointer Accessibility permissions the first time. It'll prompt you and link you straight to the right System Settings pane. Takes about ten seconds and you only do it once.
The offline angle
LacPointer supports bringing your own API keys — Claude, GPT, or local models via Ollama. If you're running voice control with a local model, the whole thing works without any data leaving your machine. That's not a niche use case anymore; plenty of people run Ollama on an M-series Mac with plenty of RAM, and the latency is fine for voice commands.
For most users though, connecting a Claude or GPT key and going Pro is the path of least resistance. Unlimited tokens means voice sessions don't get cut short mid-instruction.
The thing that surprised me most
I expected voice control to be useful for obvious hands-free scenarios — cooking, eating, hands dirty. And it is. But the bigger shift was using it while my hands are free but my attention is split.
Reading something long on screen, I'll voice-control a side task without breaking my reading flow. My eyes stay on the article, my hands stay off the keyboard, and a Slack message gets sent in the background. It sounds small. It accumulates.
Try it today
If you have LacPointer installed and haven't used voice control, do this right now: press Cmd+Shift+V and say "open [any app you use]." See if it opens. Nine times out of ten it will, and that's usually enough to make it a habit.
If you don't have LacPointer yet, it's a free download at lacai.io/download. The Free tier gives you 4,000 tokens every 15 hours — more than enough to try voice control properly before deciding whether Pro is worth it for you.
And if you want to go deeper: create a Persona specifically for voice commands with a tight system prompt, set it as your default, and see how much of your desktop you can run without touching the mouse.
