Install it before the next one starts.
Per-user installer — no admin rights, no UAC prompt. It updates itself from then on.
Intel and AMD — what most people want
Windows on ARM
Not yet — it would only hear your side of the call. See below
First launch
It asks for an API key — Anthropic, OpenAI, Google or xAI, at least one. Keys are validated against the provider before they are saved, then stored encrypted by the OS. Add a Deepgram key too if you want it to hear rather than be typed at.
The install warning
The builds are not code-signed yet. Windows SmartScreen shows an “unrecognised app” notice — More info → Run anyway. macOS refuses a double-click, so right-click → Open, then confirm. Gatekeeper remembers.
Why macOS is not up yet
Electron’s loopback audio device is Windows-only, so a Mac install would transcribe your microphone and not the other side of the call — you would need a virtual audio device such as BlackHole routed through your call app just to get back to parity. Shipping that as a download before it has been tested on a Mac would be a support queue, not a release. Windows is the tested platform.
Linux
Not shipped. Linux has no content-protection facility, so the overlay would appear in every screen share — which makes it a different product rather than a missing build.
Free tier needs no account. Pro adds screen context when you want it.
