Cloak

At my last role, I led a horizontal sharding project that moved us from a single Postgres instance to a distributed setup — 3 key steps:

Identified read vs write bottlenecks with pg_stat_statements
Added read replicas + PgBouncer connection pooling
Hash-sharded on user_id once reads were stable

Result: sustained 12x peak load. Happy to walk through trade-offs…

Stripe keeps coming up in my work. We integrated with your API at Google and every time something broke, it was on our side, never yours. This role sits right at the intersection of reliability and developer experience.

Reviews

Used by engineers who got the offer

I used Cloak for three back-to-back technical interviews in one week. Landed all three offers. The NeetCode-style answer breakdowns are insane — it literally thinks through the problem with me in real time.

Ananya K.

Senior SWE · FAANG offer

I've used bots before — they always show up in the participant list. Cloak is just gone. Screen share shows nothing. My interviewer had no idea.

Marcus T.

Staff Engineer · L6 offer

The Career Workspace saved me 8 hours of prep. Resume + JD in, gap analysis + 40 mock questions + a negotiation script out. Then I went live during the call.

FAQ

Frequently asked questions

Can't find the answer you're looking for? Check the GitHub docs.

Is Cloak really undetectable?: Yes. Cloak uses the macOS kCGScreenRecordingExcluded content-protection flag on an NSPanel window — an OS-level instruction that tells macOS not to include the window in any screen capture. Zoom, Teams, Google Meet, QuickTime, and all other screen-sharing tools render a blank region where Cloak was. The flag cannot be bypassed without kernel-level access the interviewer doesn't have.
Does it work with Zoom, Teams, and Google Meet?: Yes. Cloak works with any video call software because the protection flag is enforced at the OS display-compositing layer — not at the app level. Zoom can't see it any more than it can see other protected windows like DRM video.
Is my data safe?: In BYOK mode, audio is processed by your chosen provider with your own key — Cloak never proxies it. In Managed mode, audio routes through Cloak's backend; key material is Cloak-owned but never logged or shared. The Exa key for company dossier is stored locally and sent only to Exa.
Can I use my own API keys?: Yes — BYOK is a first-class tier. You can supply keys for OpenAI, Anthropic, Google, or Groq. Keys are stored in the macOS keychain via the Tauri keychain plugin, never in plaintext. You can also use a custom curl template to point Cloak at any HTTP endpoint, including self-hosted models.
What Mac hardware does it support?: Cloak ships a universal binary — native Apple Silicon (M-series) and Intel. macOS 12 Monterey or later required for the NSPanel APIs.
How is this different from Otter.ai or Fireflies?: Otter and Fireflies join your call as a visible bot, upload your audio, and produce notes after the call ends. Cloak runs locally, is invisible, and answers in real time during the call. It's a live copilot, not a post-meeting transcription service.
Is Career Workspace included for free?: Yes — Career Workspace (gap analysis, mock questions, prep dashboard, negotiation script, tailored resume) is included with BYOK using your own AI key. Company Dossier requires a free Exa API key from exa.ai.
