Common questions
Is there a free alternative to LockedIn AI?
Cloak is free forever with no credit metering. LockedIn AI sells credit-based plans plus unlimited tiers in the range of roughly $55 to $120 per month. Cloak has no plans at all: you connect your own API key and pay the model provider directly.
Does LockedIn AI include stealth on every plan?
No. Stealth is not included on all of LockedIn AI's tiers, so the invisibility depends on which plan you are paying for. In Cloak, screen-capture exclusion is how the window is built rather than a feature flag, so it cannot be absent.
Is a Chrome extension or a native app better for interviews?
A native app, if invisibility matters. A browser extension renders inside the browser window, so anything capturing that window captures the extension too. A native macOS app can ask the window compositor to exclude it from every capture stream, which is what Cloak does.
What does LockedIn AI do that Cloak does not?
It supports Windows and offers a browser-extension workflow, and it handles model access for you so you never create an API key. Cloak is macOS-only and requires you to bring your own key.
