Download TUNLstack
Free 8-day trial — the full app. No card required.
Add the editor extension
One extension covers VS Code and VS Code-compatible editors — it wires your AI sessions into the voice layer, with the in-editor karaoke panel in VS Code.
Install the Windows app
The desktop app runs the local voice engine and the always-on karaoke bar — the same brain behind every editor. It starts your free 8-day trial on first run.
About the Windows warning
Because TUNLstack is a brand-new independent app, Windows may show a blue SmartScreen warning the first time you run the installer. That's expected for a new app — it isn't a sign that anything is wrong.
Why does Windows show this?
SmartScreen trusts apps that many people have already installed. TUNLstack is new, so it hasn't built that reputation on Windows yet — the warning eases as more people install it. A code-signed build is on the way to smooth this over.
