Invisible desktop AI copilot that feeds you LeetCode answers during live coding interviews.

Best for

Pick Interview Solver if you want a stealth desktop overlay that turns LeetCode-style interview questions into instant, hotkey-driven AI answers.

Skip if

Skip it if you care about interview integrity, need a general-purpose coding assistant, or work somewhere that would treat its use as fraud.

Interview Solver is a desktop app that sits on top of your interview window and pipes screen captures plus interviewer audio into an AI model, returning solutions, explanations, and flowcharts in real time. It markets itself as undetectable on Zoom and similar screen-sharing tools, with global hotkeys, voice transcription, and a companion mode that lets you read answers off a secondary device. The training set is pitched as the full LeetCode catalog, with syntax-highlighted code generation on demand.

This is squarely aimed at software engineers grinding the FAANG interview loop, and the landing page leans hard on compensation figures to justify the $39/month subscription (a $0, 10-message trial is available with no card). The differentiator isn't model quality, it's the cheat-mode packaging: stealth overlay, hotkey-driven capture, and second-screen output designed to be invisible to the interviewer. The underlying LLM isn't disclosed.

Ethically this is a gray-to-black product depending on your view of interview integrity, and most employers would consider its use grounds for rescinding an offer. As a tool, it's a well-built, narrow-purpose AI overlay; as a career bet, it's risky.

Editor's take

Technically this is a competent, purpose-built AI overlay with thoughtful UX (hotkeys, companion mode, stealth). Editorially, we'd note it sits in clearly unethical territory the moment it's used in a real interview rather than for self-practice. Buyer beware: the listed FAANG comp is also what you stand to lose if you're caught.

Pros

✅ Designed to be invisible during Zoom screen sharing
✅ Global hotkeys avoid tab-switching mid-interview
✅ Companion-device mode keeps the answer off the shared screen
✅ Voice transcription captures the interviewer's prompt automatically
✅ Cheap relative to a senior-engineer comp bump

Cons

⚠️ Using it during a real interview is a fireable / offer-rescinding offense at most employers
⚠️ Underlying AI model is not disclosed
⚠️ Narrow use case; useless outside coding interviews
⚠️ No free permanent tier beyond a 10-message trial
