The 5 best Ultracode alternatives in 2026

By The Assistly team · June 1, 2026

Ultracode has a real pull: it's a native Windows and macOS coding co-pilot that produces strong answers for algorithm and system-design questions using top-tier models. If your only goal is a hard LeetCode-style round, the raw answer quality is genuinely good.

But a lot of people start shopping for alternatives anyway. Here's why — and what to use instead.

Why people look for an Ultracode alternative

A few recurring reasons show up in reviews and forum threads:

• It's coding-only. Ultracode is built for technical interviews. If you also have behavioral rounds, recruiter screens, meetings, or sales calls, it doesn't help you there. Reviewers also report it's poor for behavioral interviews specifically.
• The price is high and unpredictable. Ultracode is reported as a roughly $899 one-time "lifetime" purchase — but buyers report the price swinging anywhere from ~$650 to ~$1,799, and it's non-refundable. Several users say refund requests were denied. (Pricing changes; verify current numbers on Ultracode's own site.)
• Documented "caught" reports. On forums like TeamBlind, one user described being caught on a Meta phone screen due to repeated screen-switching; others reported being flagged on HackerRank with offers withdrawn. These are user accounts, not vendor claims, but they're worth knowing about.
• Stability complaints. Reviewers report lag, freezes, and crashes — exactly when you can least afford them, on a hard question.

If any of that resonates, the good news is the rest of the market has moved toward broader, lower-commitment, and (when engineered well) less-detectable tools.

Below are five alternatives, starting with our pick.

1. Assistly — the broad, low-commitment pick

We build Assistly, so treat this as our case rather than a neutral verdict — but the contrast with Ultracode is the whole point.

Assistly is a native desktop app for macOS (Apple silicon, macOS 13+) and Windows 10/11. It runs as an always-on-top overlay and acts as a real-time AI copilot for live conversations — job interviews, meetings, and sales calls. It is not a notetaker bot; it never joins your call as a participant.

Where Ultracode is coding-only, Assistly is built for the whole job hunt and beyond:

• Broad use, not just LeetCode. Technical rounds, behavioral rounds, recruiter screens, team meetings, and sales calls all run through the same app.
• Truly undetectable — on a real mechanism. The overlay is excluded from screen capture at the OS level, so it never appears in a screen share, recording, or screen-monitoring tool's frame. We anchor "undetectable" on that and nothing more — it doesn't defeat keystroke or hotkey detection.
• Renamable app + custom icon. You can rename Assistly and swap its icon, so it doesn't show up as a recognizable assistant in Activity Monitor or Task Manager. That defeats the name-based process scans some proctoring platforms (e.g. HackerRank, Codility) use — a direct answer to the "flagged on HackerRank" reports around Ultracode.
• Personas and knowledge modes. Build a persona from your CV, notes, and docs so answers sound like you, and switch knowledge modes for different situations. This is what keeps behavioral answers from reading like a generic model dump — Ultracode's weakest area.
• Multi-speaker context. It separates your voice from others and tracks who said what across the call, which matters on busy group calls.
• Works with headphones on. It captures the call's own audio, not just your mic, and works alongside Zoom, Google Meet, Microsoft Teams, Webex, Slack huddles, and phone calls.
• Custom hotkeys to show, hide, and drive the overlay, plus auto-generated notes and action items after every session.

The commitment is the headline difference. There's no four-figure lifetime gamble:

No credits, no separate "undetectability" tier, no $899 leap of faith. Try it free, then pay monthly if it earns it.

One honest caveat that applies to every tool here, us included: OS-level screen-capture exclusion is real but conditional. Newer macOS capture paths (ScreenCaptureKit on macOS 15+) can composite visible windows before capture, and exclusion behaves differently for whole-screen vs single-window sharing. Invisibility depends on how well a tool stays current with OS changes — it isn't a magic constant. Use any of these within the rules of your interview or meeting, and respect recording-consent laws.

2. LockedIn AI

Reported price: ~$49.99/month (down to ~$29.99 quarterly); lifetime up to ~$1,499.

LockedIn AI is a real-time interview and meeting copilot for macOS and Windows (beta), plus a Chrome extension. Its genuine strength is strong live coding support, which makes it a reasonable like-for-like swap if coding is your focus.

The trade-offs: reviewers on Trustpilot describe a 4–5 second "latency stare" before answers, generic GPT-style responses, and refund/cancellation complaints. The browser extension is visible on screen share, and reviewers report it's detectable via process-list scans on HackerRank and Codility — so it doesn't solve the same detection problem Ultracode buyers hit. Verify current pricing on LockedIn AI's site.

3. Interview Coder

Reported price: ~$299/month or ~$799 "lifetime"; no stated refund policy.

Interview Coder is a coding-interview-only overlay for macOS and Windows. The current "2.0/3.0" is a relaunch under new ownership (the original, by Roy Lee, became Cluely). If you want a focused coding tool that's cheaper than Ultracode's lifetime price, it's in the conversation.

The reported downsides are significant: reviewers cite ~20-second latency and solutions that failed test cases, plus documented CoderPad detection (users say they were "blacklisted"). On macOS, Zoom's default capture can see the overlay. It's coding-only, so behavioral and meeting needs are out. Confirm pricing and any refund policy before buying.

4. Interview Solver

Reported price: ~$39–49/month; free tier of 10 messages.

Interview Solver is a cheaper coding-interview overlay for macOS and Windows, with a phone "Companion Mode" and an iOS app. The lower monthly price and free tier make it an easy way to test the category without a large outlay.

Reviewers report it's not truly real-time — it mainly transcribes and relies on a manual trigger — with lag, freezes, and crashes on hard questions, plus inconsistent code and a clunky UX that eats screen space. Some noted the App Store app had broken functionality (the developer says it's fixed). Coding-only. Check the current free-tier limits and price on their site.

5. Cluely

Reported price: Free (~5 AI responses/day), Pro ~$20/month, "Pro + Undetectability" ~$149.99/month, Enterprise ~$200/seat.

Cluely is the biggest brand in this space (a16z-backed) and the broadest: a real-time overlay across sales, meetings, and interviews, with CRM and enterprise features, on macOS, Windows, and iOS. If brand maturity and breadth matter most, it's the obvious name.

But the parts that compete with Ultracode come at a cost. The undetectability feature is gated to the ~$149.99/month tier — far above a flat monthly plan. Independent tests measured 5–10s+ latency against an advertised ~300ms, and the overlay was flagged within seconds on CoderPad and HackerRank in those tests. Trustpilot sits around 1.8/5, dominated by billing, refund, and cancellation complaints. And in March 2026, founder Roy Lee admitted to TechCrunch that a prior $7M ARR figure was fabricated. Verify current pricing and tiers on Cluely's site.

How to choose

• You only do coding rounds and want raw answer quality: Ultracode, LockedIn AI, or Interview Coder are the closest matches — just go in aware of the detection and stability reports.
• You want the broadest tool and don't mind paying for the top tier: Cluely.
• You want the cheapest way to test the category: Interview Solver's free tier or Assistly's free plan.
• You want one tool for interviews, meetings, and calls, at a flat $14.99/month, with OS-level invisibility and a renamable process: that's the case for Assistly.

Whatever you pick, use it honestly — to be prepared and present, within the rules of the meeting or interview, and within recording-consent laws. You control your data and can delete sessions and notes anytime.
