The 8 best AI interview assistants in 2026

By The Assistly team · June 12, 2026

There are a lot of AI interview assistants now, and the category is genuinely confusing. Some are broad copilots for any live conversation. Some only solve coding puzzles. Some live in a browser tab where a screen share can see them. Prices range from free to nearly $1,800.

This roundup ranks the ones worth knowing in 2026. For each tool you get one real strength, one defensible weakness (attributed to reviews, vendor docs, or independent tests), the reported price, and whether it's broad (interviews, meetings, sales) or coding-only. Prices change constantly — always verify on the vendor's own site before you buy.

A quick note on "undetectable," since every tool in this space leans on the word: the only mechanism we'll stand behind is OS-level screen-capture exclusion, which keeps an overlay out of a screen share or recording. It's real but conditional, and it depends on a vendor keeping current with OS updates. We dig into exactly how that works in how undetectable AI overlays work.

1. Assistly — best overall

Type: broad (interviews, meetings, sales calls).

Assistly is a native desktop app for macOS (Apple silicon, macOS 13+) and Windows 10/11. It's an always-on-top overlay that gives you real-time, token-by-token guidance during live conversations. It is not a browser extension and not a notetaker bot — it never joins the call as a participant.

Why it's #1:

• Truly undetectable, the honest way. The overlay is excluded from screen capture at the OS level, so it never appears in a screen share, recording, or proctoring tool's frame. You can also rename the app and swap its icon, so it doesn't show up as a recognizable assistant in Activity Monitor or Task Manager — which defeats the name-based process scans some platforms (HackerRank, Codility) run.
• Multi-speaker context. It separates your voice from everyone else's and tracks who said what, which matters on busy group calls.
• Works with headphones on. It captures the call's own audio, not just your mic.
• Personas tuned to you. Build a persona from your CV, notes, and docs so answers sound like you, not like generic GPT.
• Auto-assist. On by default: it detects the interviewer's question the moment it's asked and answers it in your thread automatically — no hotkey fumbling under pressure. Toggle it off anytime to go manual-only. Details in auto-assist: hands-free answers.
• Customizable hotkeys, knowledge modes, and auto-generated notes after every session.

Honest limits: audio streams to the cloud, where transcription and inference run — this is not on-device processing. And like every overlay, OS-level invisibility is conditional on the engineering keeping pace with new OS capture paths.

Reported price: Free = 5 sessions/month, capped at 45 minutes each, full feature set, no card. Pro = $14.99/month for unlimited sessions with no time cap. Every feature is in both plans — there's no separate "undetectability" upsell.

2. Final Round AI — best for practice + prep

Type: broad (job-interview suite).

Genuine strength: Final Round AI is an all-in-one job suite — live Interview Copilot, AI mock interviews, a résumé builder, and auto-apply. The mock-interview practice in particular is well praised by users.

Attributed weakness: Trustpilot reviewers report it's hard to cancel and that they were rebilled after cancelling, with refunds denied despite an advertised "3-day guarantee." Some describe the live Copilot as generic and laggy, occasionally stopping mid-interview, and note the browser version is detectable on a screen share.

Reported price: roughly $99–$149/month monthly, around $500/year, with add-ons extra. Verify on their site.

3. LockedIn AI — strong on live coding

Type: broad (interview + meeting copilot).

Genuine strength: reviewers single out its live coding support as strong, and it ships on macOS, Windows (beta), and as a Chrome extension.

Attributed weakness: Trustpilot and other reviews describe a 4–5 second "latency stare" before answers and generic GPT-style responses. The browser extension is visible on a screen share, and users report it's detectable via process-list scans on HackerRank and Codility, plus the usual refund and cancellation complaints.

Reported price: around $49.99/month (dropping to roughly $29.99 quarterly), with lifetime tiers reported up to ~$1,499. Verify before buying.

4. Sensei AI — fast, but browser-based

Type: broad-ish (interview copilot, but interview-focused).

Genuine strength: sub-second latency, 30+ languages, and solid résumé personalization. When speed is your only criterion, it's quick.

Attributed weakness: it's browser-based — a web app plus Chrome extension, so you have to join the call in a browser tab and there's no native desktop overlay. Reviewers report the extension is visibly active during screen sharing (one tester was caught in 2 of 5 meetings), answers can read as AI-generated, and Trustpilot sits around 3.2/5 with refund and support complaints.

Reported price: about $24/month annual or ~$89/month monthly, with free 15-minute sessions. Verify on their site.

5. InterviewMan — interview-only, broad integrations

Type: interview-only (no meetings or sales).

Genuine strength: a focused live-interview assistant with desktop (Windows/macOS), iOS/Android, and a Chrome extension, plus broad integrations. It responds only to the interviewer's audio.

Attributed weakness: no partial refunds — reviewers report owing the rest of an annual plan after cancelling, and being charged right after registration. A Trustpilot reviewer reported a mid-interview crash; others note limited system-design depth, a rough macOS first-run setup, and no mock-interview prep.

Reported price: $30/month, or $12/month billed annually ($144/year). Verify before buying.

6. Interview Coder — coding interviews only

Type: coding-only.

Genuine strength: a purpose-built coding-interview overlay for macOS and Windows, now relaunched as "2.0/3.0" under new ownership (the original, by Roy Lee, became Cluely).

Attributed weakness: reviewers report ~20-second latency and solutions that failed test cases, plus documented CoderPad detection where users were "blacklisted." On macOS, Zoom's default capture can see the overlay. It does coding interviews and nothing else.

Reported price: around $299/month or ~$799 "lifetime," with no stated refund policy. Verify on their site.

7. Interview Solver — coding, with a phone companion

Type: coding-only.

Genuine strength: a coding-interview overlay for macOS/Windows with a phone "Companion Mode" and an iOS app, so you can read off a second device.

Attributed weakness: reviewers say it's not truly real-time — it mostly transcribes and waits for a manual trigger — and report lag, freezes, and crashes on hard questions, inconsistent code, and a clunky UI that eats screen space. The App Store app reportedly had broken functionality (the developer says it's fixed).

Reported price: about $39–49/month, with a free tier of 10 messages. Verify before buying.

8. Ultracode — strong answers, steep price

Type: coding-only.

Genuine strength: native Windows/macOS app with strong coding and system-design answers powered by top-tier models.

Attributed weakness: there are documented "caught" reports on forums — a TeamBlind user caught on a Meta phone screen due to repeated screen-switching, and others flagged on HackerRank with offers withdrawn. Reviewers report lag, freezes, and crashes, it's weak on behavioral interviews, and it's non-refundable with refund requests denied.

Reported price: around $899 one-time "lifetime," though buyers report a volatile $650–$1,799 range. Verify on their site.

Worth a mention: LeetCode Wizard

Type: coding-only. A coding tool that openly bills itself as a "cheating app" (Windows/macOS/Linux plus a web-view mirror to a second device). Its creator described it on Hacker News as a "fairly simple ChatGPT/Claude wrapper," and the vendor's own docs admit some screen-share software can bypass the hide mode — they recommend reading answers off a separate phone, which reviewers find awkward. Reported price is about €49/month ($58), far pricier than legit prep like LeetCode Premium ($13/mo) or NeetCode (~$10/mo).

Comparison table

How to choose

• Want one tool for interviews, meetings, and sales calls? Go broad. Assistly, Final Round AI, and LockedIn AI all qualify; coding-only tools won't help in a behavioral round or a client call.
• Care most about staying off the screen share? Favor a native overlay with OS-level capture exclusion over anything browser-based. See the most undetectable AI assistants.
• On a budget? Compare real monthly costs in our cheapest AI interview assistants for 2026 breakdown.

A word on responsible use: these tools are at their best when they help you stay prepared and present. Use them within the rules of any interview, meeting, or call, respect recording-consent laws, and remember that employer policies differ widely on what's allowed.

The bottom line

If you only need to beat coding puzzles, a coding-only tool may do — just price in the detection risk. But for most people interviewing in 2026, a broad, native, genuinely undetectable copilot is the better bet, and Assistly delivers that at a flat $14.99/month with no feature gating.
