Free AI Interview Copilots in 2026: 9 Compared

“Free” means very different things across AI interview tools, and this page sorts that out. Some are a metered trial you’ll eventually pay for (SyntaxCue’s free hints, Cluely’s Starter tier). Some are permanently free but limited (OphyAI’s one-time credits, Hedy’s monthly hours). And a few are genuinely free to run indefinitely — source-available or open-source tools you can use at zero ongoing cost, sometimes even without an API key. That last category is what this page adds that our broader best AI interview copilots roundup doesn’t: two tools, Natively and OpenCluely, that live entirely in the free/self-hosted space. Below we cover those two in depth, explain SyntaxCue’s own free tier honestly, and recap the other tools’ free terms in one table so you can tell a trial from something actually free.

Natively

Natively is a source-available desktop tool that double-duties as both a meeting assistant and an interview copilot — the one genuinely relevant match on this page for the “open-source AI meeting assistant” search, though (importantly) it is not open source. Its license is the “Natively Personal Use Source License v1.0” — source-available, explicitly not open-source: free for personal, non-commercial use, but not an open-source license. A Pro tier exists via Lifetime or Yearly subscriptions, and Pro features can also be unlocked with a “$NAT token.”

What makes it genuinely $0 for personal use: it’s BYOK, or you can connect it to a local Ollama instance and use no API key at all. It runs local Whisper transcription on-device (self-reported sub-500ms latency), handles system and mic audio on separate channels, and keeps a local RAG index of past meetings via SQLite. Platforms: macOS 12+ (Apple Silicon and Intel) and Windows 10/11 — no Linux. Natively self-reports roughly 9,000 users, ~700 daily active, and ~2,300 GitHub stars; those are its own figures, not independently verified.

One thing to know going in: Natively’s own README markets unusually aggressive concealment — it describes hiding from the dock, disabling popups, and “Process Disguise (Masquerading)” to make the process appear as Terminal or Settings in the OS. That’s a materially more invasive approach than the overlay tricks other tools use, and we’re noting it as a fact about Natively’s own positioning, not endorsing it.

OpenCluely

OpenCluely is the genuinely open-source option here — MIT licensed, which is the real distinction from Natively’s source-available-but-not-open-source status. It’s free, with no subscription, and built specifically for technical interviews: DSA problems, online assessments, and competitive-programming rounds. Features include an overlay that its authors say recording and conferencing tools don’t capture, real-time AI help, image-based question capture, multi-language support, no data collection or telemetry, local processing, and encrypted-in-transit requests to the AI provider. As with Natively, OpenCluely markets itself with “invisible” framing — that’s its own language about its own project, cited here as fact, not something we adopt.

OpenCluely also isn’t the only independent open-source Cluely-style clone on GitHub — a few other unrelated repositories use similar naming — which is real evidence that “I want a free, self-hosted version of this kind of tool” is a genuine, if niche, demand. We won’t deep-dive the others; OpenCluely is the clearest MIT-licensed example to point to.

SyntaxCue’s free tier

SyntaxCue is a paid tool ($79 once), but it has a free-to-try tier, which is why it belongs on this page alongside the genuinely free options — as long as we’re clear about which kind of “free” it is. It’s a metered trial: you get around 10–15 hints free, with no card required to try. After that, it’s a one-time $79 purchase for unlimited use for a 6-month license — there’s no subscription, no auto-renewal.

Worth being precise about how the free period works, because it’s unusual: SyntaxCue is BYOK the whole way through — you supply your own OpenAI or Anthropic key from the start, during the free tier and after purchase. So the free hints aren’t ad-subsidized or feature-crippled; the app is fully functional, just usage-capped until you buy. Audio is transcribed locally, and there’s an optional setting that keeps the hint window out of your own screen-capture stream when you share your screen — it’s off by default and you can turn it off any time.

The other tools’ free tiers, briefly

Here’s what “free” actually gets you on the other tools covered in the full roundup — one line each; see that page for complete pricing and features.

Open-source AI meeting assistants

If what you want is a free, open-source tool for general work-call notes rather than live interview answers, that’s a different category with its own open-source options — but it’s not this page’s focus; Natively is the one tool here that genuinely spans both the interview-copilot and meeting-assistant roles.

Which free option should you pick

If you want something that stays free indefinitely and you’re comfortable with a bit of setup, the two self-hosted options lead: OpenCluely if you specifically want a genuinely open-source (MIT) interview tool, or Natively if you want a more full-featured desktop app and don’t mind that it’s source-available (not open-source) with a paid Pro tier — and, notably, Natively can run entirely free with a local Ollama model, no API key at all. If you’d rather just try a polished paid tool before committing, SyntaxCue’s ~10–15 free hints (no card, BYOK from the start) let you evaluate the real product, and OphyAI (5 one-time credits) or Hedy (5 hours/month) offer permanently-free-but-limited access. And if a tool markets itself heavily around concealment — as several free options here do — weigh that against what your interview process actually permits before relying on it.
