A focused coding-interview copilot that nails the core stealth + screengrab loop on Zoom and Meet, but ships with rough edges (occasional freezes, manual re-triggering, fiddly transparency) and recent third-party tests have flagged detection risk on enterprise proctoring platforms. Solid for LeetCode-only loops; thin if you need broader prep.
Interview Solver is purpose-built for one job: surface a LeetCode answer on your screen during a live coding round without showing up in the screenshare. The screengrab + global hotkey + translucent overlay loop is genuinely useful when it works, and companion mode (mirroring to a second device) is a thoughtful answer to heavily monitored sessions. But it's a small startup launched in 2024 — third-party reviewers report freezes on first launch, transparency settings that don't always apply, and a workflow that often requires manually re-triggering the AI rather than auto-answering transcribed questions. Detection has also been disputed: a 2026 round-up testing competitors against CoderPad, HackerRank, and CodeSignal flagged peers like Interview Coder and Cluely as detectable when hotkeys fire, and Interview Solver uses the same hotkey-registration pattern. Treat invisibility claims as best-effort, not guaranteed.
Stability is the most common complaint. Reviewers describe the app freezing on first launch (black screen that won't close), occasional crashes mid-session, and transparency settings that silently fail to apply — leaving the overlay opaque and visible.
The workflow isn't as automated as the marketing implies. Several reviews note that transcription captures the question but the AI doesn't auto-answer; you still have to fire a hotkey or paste manually, and the response area takes up enough screen real estate that you'll be minimizing windows mid-interview.
Detection risk is the bigger long-term concern. Independent 2026 testing on CoderPad, HackerRank, and CodeSignal showed that tools using global hotkey registration — the same pattern Interview Solver relies on — get flagged with 'unauthorized application interaction detected' alerts within seconds. Zoom invisibility is capped at v6.16; newer Zoom builds are not guaranteed.
“Not very stable — its workflow is quite confusing, sometimes even freezing or crashing.”
Interview Solver is an invisible desktop AI copilot built specifically for coding interviews — it provides real-time answers to LeetCode and system design questions while staying undetectable to Zoom screen sharing and proctoring. Features include screengrabs for AI-powered solutions, voice transcription of both candidate and interviewer, and a companion-mode for using a second device.
Interview Sidekick is lauded for its intuitive platform, enhancing technical interview skills and increasing confidence during interviews — combining a 10,000+ question bank with real-time copilot assistance for the full prep funnel.

Interview Solver is a desktop app you install on macOS. Once running, you use undetectable global hotkeys to capture screenshots of LeetCode problems, transcribe interviewer audio for context, and surface AI-generated solutions on a translucent overlay. The 'companion mode' lets you display code on a separate device for proctored sessions where the primary device is heavily monitored. Pricing is $39/month after a free trial limited to 10 messages.
