First-launch setup (takes 30 seconds)
Klayr is independently distributed — your OS may ask you to confirm it's allowed to run. This is a one-time step and completely normal for apps distributed outside official app stores.
macOS
- Open the
.dmgand drag Klayr to Applications. - If macOS says the app can't be opened, run this once in Terminal:
xattr -cr "/Applications/Klayr.app"
Or go to System Settings → Privacy & Security and click Open Anyway. One-time step.
Windows
- Run
Klayr-Setup-x.x.x.exe. - If Windows shows a “publisher unknown” message, click More info → Run anyway.
- Follow the installer. Done.
This prompt appears for all independently distributed apps. It's a one-time confirmation.
Linux
Make the AppImage executable, then run it:
chmod +x Klayr-x.x.x.AppImage ./Klayr-x.x.x.AppImage
For the .deb package: sudo dpkg -i klayr_x.x.x_amd64.deb
You'll be ready in three steps.
Install Klayr
Download for your platform and run it. macOS: drag to Applications. Windows: run the installer. Linux: make executable, then run. First-launch notes below if your OS asks for confirmation.
Add your AI key
Open Klayr → Settings → API Keys. Paste a key from Google, OpenAI, or Anthropic. Google's Gemini has a free tier — no card needed. The whole thing takes under a minute.
Start your session
Launch Klayr before your interview, pick your interview mode, and let it run. It stays invisible in the background, ready the moment a question appears.
