Interview Solver vs Interview LLM: side by side

As of Nov 14, 2026:

Cost over a typical 3-month search

This is the clearest difference between the two, because both vendors publish their prices. Three months is a common length for a job search with several loops; here's what each option costs over that window and over six months, as of Nov 14, 2026:

The Interview LLM figures assume 300 problems a month, a heavy prep pace, on Claude Sonnet 5.5 ($2 per million input tokens, $10 per million output), with each problem using about 3,000 input and 2,500 output tokens, as in our bring-your-own-key cost guide. That's about $0.031 a problem, or $9.30 a month. Treat it as an illustration: a reasoning-heavy model or long problems will cost more, and a smaller model such as Gemini 3 Flash Preview ($0.50 / $3) costs a fraction of that. You pay the provider directly, so you can check the actual spend in their dashboard at any time.

The Interview Cycle plan is the better Interview Solver deal if your search fits inside three months. Interview Solver's free tier is cheaper than any of these, but its limits weren't stated, so we can't say how far it goes.

Audio and a phone, or screenshots

Beyond price, the two apps take in information differently. Interview Solver lists voice transcription of both the interviewer and candidate audio, a companion mode that lets you use your phone as a remote control, and document upload so the AI has your resume and the job description as context. It also lists system design assistance alongside code generation.

Interview LLM doesn't listen. It works from what's on your screen: press a global shortcut to capture the problem (up to two screenshots queue up), and it extracts the problem statement, then writes a solution with an explanation and time and space complexity. If your code throws an error or fails a test, screenshot the error or your code and ask for debugging help. Window position, size, opacity and zoom are all on keyboard shortcuts. For system design rounds there's a separate app, System Design LLM, also $39 once.

Which input style is better depends on the round. In a coding round the problem is usually written out on screen, in the editor or assessment page, so a screenshot captures it exactly, constraints and examples included. Audio is more useful when the question is spoken or the conversation drifts into follow-ups.

AI models and where your data goes

Interview Solver's pages don't say which AI models it runs or whether you can use your own key; the AI is part of the subscription. That's simpler if you don't want to think about it.

Interview LLM goes the other way. You add an OpenAI, Anthropic (Claude) or Google (Gemini) API key and choose the model for each stage: extraction, solution and debugging. Your key and session data stay on your machine, and the only outbound calls go to the provider you picked. We don't run servers that store your data, and the full source code is included in the download, so you can read exactly what it sends or build it yourself.

When Interview Solver may suit you better

• You want the app to transcribe what the interviewer says, not just read the screen.
• You like the idea of controlling it from your phone.
• You want resume and job description context fed to the AI.
• You want code and system design help in one subscription.
• You'd rather not manage an API key, or you want to try a free tier before paying.

When Interview LLM may suit you better

• Your search may run past one Interview Cycle, and you'd rather pay once than renew.
• You want to know and choose the model, and switch when a better one ships.
• You care where your data goes and want source code you can inspect.
• Your rounds are mostly written coding problems and online assessments, where a screenshot captures everything.

If that's you, see pricing and what's included. Apps and source code arrive by email within 24 hours, usually within an hour.

A note on interview rules

Interview Solver advertises invisible screen sharing and hotkeys. That's the vendor's claim, and we don't make claims about any tool's visibility. Many employers and assessment platforms prohibit outside help during live interviews and online assessments; read the rules for each round and stick to them. Both apps work well for practice: get a worked solution and complexity analysis, then close it and solve the problem again from scratch.
