The cheapest AI interview assistants worth trying in 2026

By The Assistly team · June 10, 2026

"Cheap" is easy. A $10 tool that lags ten seconds, gives you generic answers, and shows up on your screen share isn't cheap — it's expensive, because it costs you the interview. So before we rank anything by price, here's the rule we used: a cheap AI interview assistant only counts if it's actually usable in a live interview.

That means low latency, answers that sound like a human (not a documentation page), and — if you're going to use it during a screen share — an overlay that's genuinely withheld from the capture, not "mostly hidden." Anything that fails those tests isn't a bargain at any price.

This roundup ranks real-time interview copilots by value for money in 2026. All prices below are reported and change often — always verify on the vendor's own site before you pay. Where we flag a weakness, it's attributed.

The short version

Prices reported as of writing; confirm current pricing on each vendor's site.

Why headline price can mislead

Two traps make a "cheap" tool cost more than it looks:

• Annual lock-in with weak refunds. A low monthly-equivalent price often requires paying for a full year up front. If you can't cancel cleanly, the real price is the whole year.
• The undetectability upsell. Some tools advertise a low base price, then put the feature you actually need for a proctored or screen-shared interview behind a much more expensive tier.

Keep both in mind as you read the ranking.

The ranking

1. Assistly — $14.99/mo flat, and a free plan you can actually use

Assistly is a native desktop overlay for macOS (Apple silicon, macOS 13+) and Windows 10/11 — not a browser tab, not a bot that joins your call. It streams guidance token by token in real time, separates your voice from everyone else's so it tracks who said what, and works with your headphones on because it captures the call's own audio, not just your mic.

On pricing it's deliberately boring, which is the point:

• Free: 5 sessions per month, up to 45 minutes each, the full feature set, no credit card.
• Pro: $14.99/month for unlimited sessions and no time cap.

There are no credits, no usage meters, and — critically — no separate "undetectability" tier. The mechanism that keeps the overlay out of a screen share is included on both plans. That mechanism is real and verifiable: the window asks the OS to exclude itself from capture — a built-in capability on both Windows and macOS — so it sits on your physical screen but is withheld from the capture buffer.

We'll be honest about the limits of that, because everyone should be: newer macOS capture paths can behave differently, and how reliably any overlay stays hidden depends on how well it's engineered and kept current. We cover the full mechanism — and where it does and doesn't hold — in how undetectable AI overlays work.

Assistly also lets you rename the app and swap its icon, so it doesn't appear as a recognizable assistant in Activity Monitor or Task Manager — which defeats the name-based process scans some proctoring platforms use. You build a persona from your CV and notes so answers sound like you, bind your own hotkeys, and get notes and action items generated automatically after every session.

For $14.99 flat with a usable free tier, it tops this list on value. Naturally we're biased — so check the comparisons below and the best AI interview assistants of 2026 for the wider field.

2. InterviewMan — cheapest sticker price, but read the fine print

At a reported $12/mo billed annually ($144/yr) — or $30 month-to-month — InterviewMan has the lowest headline number here. It's a live-interview-only assistant for Windows/macOS, iOS/Android, and Chrome, and it only responds to the interviewer's audio.

Genuine caveats: it's interview-only (no meetings or sales calls) and there's no mock-interview prep. On refunds, the vendor's terms describe no partial refunds, so cancelling an annual plan still leaves you owing the rest of the year — which makes that $12 effectively a $144 commitment. Reviewers on Trustpilot also report being charged right after registration, a mid-interview crash, and limited system-design depth. See Assistly vs InterviewMan.

3. Sensei AI — fast, but it's a browser tab

Sensei AI is a real-time interview copilot with real strengths: reviewers note sub-second latency, 30+ languages, and résumé personalization. Reported pricing is ~$24/mo billed annually (or ~$89/mo monthly), with a free 15-minute session.

The catch is architectural. Sensei is browser-based — a web app plus Chrome extension — so you join the call in a browser tab, with no native desktop overlay. Reviewers report the extension is visibly active during screen sharing (one tester was caught in 2 of 5 meetings), and some find the answers read as AI-generated. Trustpilot sits around 3.2/5 with refund and support complaints. It's a fine value if you'll never screen-share; otherwise the speed doesn't save you. See Assistly vs Sensei AI.

4. Interview Solver — cheap-ish, but coding-only and not quite real-time

Reported at ~$39–49/mo with a free tier of 10 messages, Interview Solver is a coding-interview overlay for macOS/Windows with a phone "Companion Mode." It's the most affordable in its niche, but reviewers say it's not truly real-time — it mainly transcribes and waits for a manual trigger — and report lag, freezes, and crashes on hard questions, inconsistent code, and a clunky UX that eats screen space. It's coding-only.

5. LockedIn AI — solid live coding, mid-tier price

At a reported ~$49.99/mo (down to ~$29.99 quarterly), LockedIn AI is a real-time copilot for macOS, Windows (beta), and Chrome. Its strength is genuinely strong live coding support. Reviewers report a noticeable 4–5 second "latency stare," generic GPT-style answers, refund and cancellation complaints, and — importantly — that the browser extension is visible on screen share and that it's detectable via process-list scans on HackerRank and Codility. For a proctored coding round, that last point matters. See Assistly vs LockedIn AI.

What "cheap" looks like at the top end

For contrast, the premium tier shows how fast price climbs once you want undetectability bolted on:

• Cluely has the biggest brand and a broad product, but its undetectable feature is reported as gated to a ~$149.99/mo tier. Trustpilot sits around 1.8/5, dominated by billing and cancellation complaints, and independent tests measured 5–10s+ latency against an advertised ~300ms.
• Interview Coder is reported at ~$299/mo, is coding-only, and has documented detection on CoderPad with no stated refund policy.
• Ultracode is reported at ~$899 "lifetime" (buyers report a volatile $650–$1,799), non-refundable, with documented "caught" reports on forums like TeamBlind and HackerRank.

None of those is cheap, and the expensive ones don't buy you immunity — they buy you a bigger bill and, in several cases, the same detection and latency complaints.

How to actually choose

• Want one flat price, a usable free tier, and undetectability included? That's Assistly at $14.99/mo.
• Want the lowest sticker price and only do plain interviews? InterviewMan at a reported $12/mo annual — but confirm the refund terms first.
• Need speed and don't screen-share? Sensei AI is fast, but it's a browser tab.
• Coding-only? Interview Solver or LockedIn AI sit mid-price; both have detection caveats on proctored platforms.

Whatever you pick, verify current pricing and the refund policy on the vendor's site before paying, and use any tool within the rules of your interview and your local recording-consent laws.
