Installing
Murmurtale is in a private beta. Apply for founding access first; if approved, use the invite code in your email to create an account. The current Mac download appears on your account page after you sign in.
Run it from ApplicationsAlways launch Murmurtale from your Applications folder (Spotlight, Launchpad, or the Dock) — not from a Downloads or project folder. macOS can run an app opened from certain synced folders as a frozen read-only copy, which makes updates look like they did not take. Applications avoids that entirely.
What happens on first launch
The first time you open Murmurtale, it downloads its on-device speech model (about 632 MB) and compiles it for your Mac's Neural Engine once. You will see progress in Preferences. This takes roughly a minute on a fast connection and only happens once.
After that, Murmurtale opens a short three-step welcome window. Step one is granting permissions.
