Common questions
Is there a free alternative to Interview Coder?
Cloak is free forever. Interview Coder's free tier is the installer with no AI functionality, so any real use requires the $299/month plan or the $799 lifetime purchase. Cloak instead uses your own OpenAI, Anthropic, or Google API key, which costs cents per interview paid directly to the provider.
Is Cloak as undetectable as Interview Coder?
Both are native macOS apps that exclude their windows from screen capture at the operating-system level, so neither appears in Zoom, Google Meet, Microsoft Teams, or a screen recording. Both also mask the process name and run without a Dock icon.
Why is Interview Coder so expensive?
Interview Coder resells model access, so its subscription covers the AI usage plus margin, and the monthly plan is metered at 1,000 credits. Cloak does not resell anything: you connect your own API key and the app is free, which removes the markup and the credit cap.
Can I switch from Interview Coder to Cloak?
Yes. Cloak requires no account, so you download it, paste in an API key, and it works. Note that Interview Coder's plans are non-refundable, so cancel before your next renewal rather than expecting money back.
