umm hope your week has started well… I was talking to Cheyene earlier but reception was really bad and I think their going to handle the first part of the project, but I'm not totally sure. Also, I told the team the the new timeline should be ready by Friday, although it's probably going to slip.

Hope your week is off to a good start. I was talking to Cheyene earlier, but the reception was really bad. I think they're going to handle the first part of the project, but I'm not totally sure. I also told the team the new timeline should be ready by Friday — although it might slip.

How It Works

Three seconds. Three steps.

1

Press Alt+X

From anywhere — even while typing in another app. Or click the mic button on the overlay.

2

Speak Naturally

The overlay shows a live waveform. Audio is captured in the background — no UI freezing.

3

Press Again

Text appears at your cursor. Clean, punctuated, ready to send. That's it.

Everything You Need

No bloat. Just the tools that matter.

🎤

Live Waveform

Real-time audio visualization that dances when you speak, goes flat when silent.

AI Text Polish

Removes "um", "uh", "like", fixes capitalization and punctuation. Optionally runs through a local LLM.

📋

Auto-Paste

Text lands at your cursor via Ctrl+V. Or just copy to clipboard — your choice.

🪟

System Tray

Minimizes to tray. Left-click to toggle overlay. Right-click for settings, mic toggle, or exit.

⌨️

Customizable Hotkeys

Alt+X by default. Change anytime in Settings — takes effect immediately. No restart needed.

🌐

99+ Languages

Choose a fast English-only model, or a multilingual model that auto-detects the language.

Private by Design

No Cloud. No Accounts.
No Tracking.

ZeroKeys runs 100% offline on your CPU. Your voice never leaves your machine. No sign-up, no data collection, no internet required — except for the initial model download. Everything happens locally.

✅ No cloud dependency ✅ No account needed ✅ No recordings saved ✅ No telemetry

Works in Any App

ZeroKeys pastes directly at your cursor. Browser, IDE, chat, email — it doesn't care.
