Installed in 5 minutes. Step-by-step for Mac and Windows.
Download "Qala-Mac.zip" and unzip it. Place the "App" folder somewhere permanent — e.g. Documents or Applications. Important: do not move the folder after installation is complete, otherwise Qala will no longer start.
Download Qala-Mac.zipOpen System Settings → Privacy & Security. Scroll to the "Security" section and set "Allow applications downloaded from" to "App Store and identified developers". You only need to do this once.
Open the unzipped folder and double-click "Installieren.command". macOS will initially block it. Go back to System Settings → Privacy & Security — you'll now see a notice with an "Open Anyway" button. Click it. A second confirmation dialog appears — click "Open Anyway" again, then confirm with your Mac password.
A Terminal window opens and installs all required packages in the background. This takes 2–5 minutes. When it's done, a "Qala starten.app" file appears on your Desktop.
Right-click "Qala starten.app" → "Open" and confirm the macOS security prompt once more. From this point on, a normal double-click is enough to start the app.
Your browser opens automatically. The setup wizard takes about 3 minutes: licence key, AI model + API key, source and target languages, admin password.
Start translation, show the QR code on the big screen — your visitors scan it and read along in their mother tongue.
Download "Qala-Windows.zip" and unzip it. Place the "App" folder somewhere permanent — e.g. Documents or C:\Qala. Important: do not move the folder after installation is complete, otherwise Qala will no longer start.
Download Qala-Windows.zipInside the unzipped folder you'll find "Installieren.bat". Double-click it. Windows Defender will ask once → "More info" → "Run anyway".
A command prompt opens and installs Python and all required packages. This takes 5–10 minutes. Please don't close the window — wait for the "Done" message.
After installation, the installer creates a "Qala starten" shortcut on your Desktop. One double-click is enough to launch.
Edge (or your default browser) opens automatically. The wizard takes you through: licence key, AI model + API key, source and target languages, admin password.
Test the mic, turn on the target languages, press "Start" — your visitors scan the QR code and follow along.
Download the Qala app for your operating system.
💡 Tip: Start with a free API key
We recommend the cloud API option (e.g. Google Gemini): translation including audio playback in 2–3 seconds. Local AI models on the same laptop take 7–15 seconds — too slow for a live sermon. A free Gemini API key easily covers a 2-hour service without hitting any limits.
Open the app, check in the dashboard that your mic is picking up sound, and press "Start recording".
In the admin panel you'll find the QR code. Show it before the sermon starts — your visitors connect within seconds.
Just close the app. Everything stays configured — next time, one click on "Start recording" is enough.
On Mac: System Settings → Privacy & Security → Microphone → enable Terminal / Qala. On Windows: Settings → Privacy → Microphone → allow desktop apps.
Laptop and phone must be on the same Wi-Fi. Check that the church Wi-Fi doesn't have "client isolation" turned on (ask your network admin).
Check the admin panel: is your API key still valid? Is there still credit on your AI provider account?
