A screen-share invisible overlay for coding interviews. Real-time coaching, code drafting, and bug detection — live during any interview, powered by Claude AI. $29/mo vs $299 at Interview Coder.
Real footage — CodeSage Pro solving a live interview problem, invisible to the screen share.
No setup, no copy-pasting, no prompts to write. CodeSage Pro reads what's on your screen and answers in under 3 seconds — like a senior engineer whispering in your ear.
Press ⌘⇧Space. CodeSage floats over your screen — your interviewer sees nothing, only you see it on your physical display.
Press ⌘⇧S. It reads everything visible — problem statement, your code, test cases — in under 2 seconds.
Coach for a hint, Draft Code for a full solution, Find Issues for the exact buggy line, Sys Design for architecture. Claude responds instantly.
CodeSage Pro uses NSWindow.sharingType = .none — a native macOS API that excludes the window from all screen capture at the OS level. Not a trick. Built into macOS.
Whether it's a live Zoom interview, a proctored Codility assessment, or full OBS screen recording — the CodeSage window simply does not appear in any captured output.
Every action auto-reads your screen — zero typing, zero prompts. Built for real interview pressure.
Completely invisible to Zoom, Meet, Teams, OBS and all recording software. Only you can see it. The Chrome extension works everywhere but is visible — invisibility is exclusive to the Mac app.
Coach gives hints without spoiling the answer. Draft Code writes a full solution with complexity analysis. Find Issues points at the exact buggy line. All under 3 seconds.
No tracking, no logging, zero retention. Prompts go directly to Anthropic's API. Voice runs 100% on-device via Apple's Neural Engine — audio never leaves your Mac.
Works on LeetCode, HackerRank, CodeSignal, CoderPad, Codility, GitHub, Replit + universal fallback for Monaco, CodeMirror & Ace editors on any site.
"I failed the Google loop twice before. The third time I used CodeSage Pro for the system design round and it was a completely different experience. Got the L5 offer."
"I used CodeSage Pro across my entire loop — Meta, Apple, and Netflix. The screen-share invisible feature is genuinely insane. It's right there on my screen the whole time and nobody has any idea."
"Brutal 4-hour take-home with screen recording on. CodeSage Pro was completely invisible the whole time. Finished all 5 problems. Couldn't have done it without Coach mode."
Same invisible overlay. Same AI-powered answers. A fraction of the cost.
