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.
- Unlimited messages on paid plan

Real-world issues users report
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 vs Interview Sidekick
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 16,000+ question bank with real-time copilot assistance for the full prep funnel.

How to Use Interview Solver
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.
How to Use Interview Sidekick
Getting started with Interview Sidekick is quick and designed to help job seekers practice and improve their interview skills with AI-powered coaching, 16,000+ real interview questions, and a real-time copilot that works on Zoom, Google Meet, Microsoft Teams, and Webex.
