Is there a free AI interview assistant?

Last updated September 9, 2026.

"Free" means three different things in this category: a limited trial, a recurring free tier with a cap, or genuinely free open-source software you run yourself. This page sorts the main options into those three buckets so you can see what you can actually use without paying — for a behavioral, sales, consulting, marketing, or management interview, not just a technical one.

Trial vs. free tier vs. open source

Free trial — full product access for a limited number of uses, then a paywall. Good for checking setup and answer quality before you pay. InterviewBeacon works this way: roughly 10–15 free suggestions, no card required.

Recurring free tier — stays free indefinitely, but capped by usage time, credits, or feature access. Hedy is an example: 5 free hours every month, renewed monthly.

Open source / self-hosted — no license fee at all, because you run the software yourself. OpenCluely, for example, is fully MIT-licensed. The trade-off: "free" here means no subscription, not necessarily no setup work or AI-provider cost.

What's free, tool by tool

This table covers only the free-use conditions. For full profiles — pricing, platforms, and feature comparisons — see the best AI interview assistant roundup.

Interview Coder is worth a separate mention: the download itself is free, but its AI features are locked behind a paid plan ($299/mo or $799 one-time), and it's built specifically for coding interviews — not the general audience this page covers.

InterviewBeacon's free trial

You can download InterviewBeacon and use the full app before buying a license. The trial includes roughly 10–15 live AI suggestions, needs no credit card, and runs the same workflow as the paid version — system audio from the call is transcribed locally on your device, then a private answer suggestion appears in real time.

You connect your own OpenAI or Anthropic API key during the trial itself; the suggestions aren't feature-limited, only capped in number. After the trial, InterviewBeacon is aone-time $79 purchase for a 6-month license, no auto-renewal, backed by a14-day, no-conditions refund. It runs on macOS and Windows.

What about genuinely free, open-source tools?

Fully free, self-hosted options do exist in this broader category — Natively (source-available, free for personal non-commercial use, and able to run without any API key via a local Ollama model) and OpenCluely (MIT-licensed, fully open source). Both are built and positioned for technical and coding interviews, and both need real technical setup: building from source, supplying your own API key, or running a local model. For someone preparing for a sales, consulting, behavioral, or management interview without an engineering background, that makes them a poor practical fit despite costing nothing — developers evaluating them for coding interviews can find a deeper look at SyntaxCue's free-tools guide.

Which free option should you pick?

You want to test a full live workflow before paying: InterviewBeacon's no-card trial gives you about 10–15 full-featured suggestions.

You need a free option with no end date: Hedy's 5 free hours a month or Cluely's Starter tier stay free indefinitely, within their limits.

You only need a handful of one-off uses: OphyAI's 5 one-time credits cover a quick, browser-based test.

You want zero license cost and don't mind technical setup: Natively or OpenCluely are worth a look — if their technical-interview focus actually fits what you're preparing for.

You want a fixed, one-time cost after the free trial: InterviewBeacon is $79 for a 6-month license, with no subscription and no auto-renewal.
