A stealth desktop overlay that reads your screen, transcribes the interviewer in real-time, and feeds you answers through the latest reasoning models. Completely invisible to screen sharing.
Cancel anytime. Works in 2 minutes.
HackerRank, CodeSignal, Karat, CoderPad — doesn't matter. The overlay is excluded from screen capture at the OS kernel level. Not a browser extension. Not detectable.
Three full interview modes with tuned prompts and structured output. Coding gives you the solution + complexity analysis. System design gives you architecture + tradeoffs. Behavioral uses your actual resume to generate stories.
Other tools use opacity tricks or alt-tab. Canopy uses WDA_EXCLUDEDC (Windows) and setContentProtection (Mac) — the same API OBS itself uses. Your interviewer, their recording, and their proctoring software all see nothing.
Competitors charge $60–150/mo for a ChatGPT wrapper with no audio. Canopy does vision + real-time transcription + multi-mode reasoning for $29/mo. You bring your own OpenAI key — no middleman markup on tokens.
"Used it for my Meta onsite. The transcription caught a clarifying question I missed and the model had the answer streaming before I finished processing what they said."
