The 5 best LeetCode Wizard alternatives in 2026

LeetCode Wizard is upfront about what it is. The creator described it on Hacker News as "a fairly simple ChatGPT/Claude wrapper," and the marketing leans into the word "cheating." That honesty is refreshing. It also tells you the ceiling: this is a single-purpose coding tool, and a thin one.

If you're shopping for alternatives, it's usually for one of a few reasons. We'll start there, then get into the options.

Why people look for a LeetCode Wizard alternative

• It's coding-only. It solves algorithm puzzles. It does nothing for behavioral rounds, system-design discussion, recruiter screens, team meetings, or sales calls. Most job searches involve far more talking than typing.
• The "hide" mode is conditional, and the vendor says so. LeetCode Wizard's own documentation admits some screen-share software can bypass its hide mode, and recommends reading answers off a separate phone. That's the vendor telling you the headline feature has gaps.
• The second-device workaround is awkward. Reviewers find glancing back and forth between a hidden answer on a second phone clumsy and obvious. It's the kind of "reading eyes" tell that interviewers watch for.
• It's expensive compared with learning the material. Reported pricing is around €49/month (~$58). For comparison, LeetCode Premium runs about $13/month and NeetCode about $10/month, and those teach you the patterns.
• Real disqualification risk. On a proctored coding platform, a tool whose hide mode is admittedly beatable is a liability.

If any of that sounds familiar, here are five tools worth considering, starting with the one we build.

1. Assistly: best overall, and not only for coding

We make Assistly, so treat this as a pitch. The core difference is structural, though: LeetCode Wizard is a code-puzzle wrapper, while Assistly is a real-time copilot for the whole conversation, covering behavioral and technical interviews, plus meetings and sales calls.

Assistly is a native desktop app for macOS (Apple silicon, macOS 13+) and Windows 10/11. It runs as an always-on-top overlay on your own screen. It is not a notetaker bot, so it never joins your call as a visible participant.

What sets it apart:

• Invisible to screen capture at the OS level. The overlay asks the operating system to exclude itself from capture buffers (the same mechanism DRM uses to black-box protected video). It's on your physical screen but withheld from screen shares, recordings, and screen-monitoring tools. This is an engineered mechanism, and unlike LeetCode Wizard, we don't ask you to fall back to reading off a second phone.
• Renamable app and 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 (HackerRank, Codility) run against a blocklist of known assistant names.
• Dedicated coding and system-design modes, plus everything else. Assistly has assist modes built for technical rounds, so it covers LeetCode-style and system-design questions as well as the behavioral side.
• Built for talking as well as typing. Personas built from your CV and notes make answers sound like you. Multi-speaker tracking separates your voice from others and follows who said what across a busy call. Knowledge modes let you load different context for different situations.
• Works with headphones on, because it captures the call's own audio, not just your mic. It runs alongside Zoom, Google Meet, Microsoft Teams, Webex, Slack huddles, and phone calls.
• Real-time streaming guidance token-by-token at low latency, plus automatic notes and action items after every session.

Pricing is flat. Free gives you 3 sessions a month (15 minutes each), the full feature set, no card required. Pro is $14.99/month for unlimited sessions with no time cap. Every feature is on both plans, and there's no separate "undetectability" upcharge.

A caveat we'll always state: OS-level capture exclusion is real but conditional. Newer macOS capture paths (ScreenCaptureKit on macOS 15+) can composite visible windows before capture and bypass the older flags, and behavior differs between whole-screen and single-window sharing. Invisibility depends on a tool staying current with OS updates. We keep ours current, and we tell you the truth about it.

2. Interview Solver: coding overlay with a phone companion

Interview Solver (interviewsolver.com) is a coding-interview overlay for macOS and Windows, with a phone "Companion Mode" and an iOS app. Reported pricing is around $39–49/month with a free tier of 10 messages.

Note: the phone companion idea appeals to people who specifically want answers on a second device.

Attributed weaknesses: reviewers say it isn't truly real-time, since it mainly transcribes and relies on a manual trigger, and report lag, freezes, and crashes on hard questions, inconsistent code, and a clunky UI that eats screen space. Reviewers also noted the App Store app had broken functionality, though the developer says it's fixed. It's coding-only. Verify current pricing on their site.

3. LockedIn AI: strong on live coding, weaker on stealth

LockedIn AI (lockedinai.com) is a real-time interview and meeting copilot for macOS, Windows (beta), and Chrome. Reported pricing is around $49.99/month (down to ~$29.99 quarterly), with a lifetime option up to ~$1,499.

Strength: users praise its live coding support specifically.

Attributed weaknesses: reviewers on Trustpilot describe a 4–5 second "latency stare" before answers and generic GPT-style responses. The browser extension is visible on screen share, and reviewers report it's detectable via process-list scans on HackerRank and Codility. There are also refund and cancellation complaints. Verify pricing before buying.

4. Ultracode: strong coding answers at a steep, non-refundable price

Ultracode (ultracode.ai) is a native Windows/macOS coding-interview "co-pilot" that produces strong coding and system-design answers via top-tier models.

Strength: the answer quality on hard algorithm and system-design problems is well regarded.

Attributed weaknesses: reported pricing is around $899 one-time "lifetime," though buyers report a volatile $650–$1,799, and it's non-refundable with refund requests denied. There are documented "caught" reports on forums. A TeamBlind user was caught on a Meta phone screen due to repeated screen-switching, and others were flagged on HackerRank with offers withdrawn. Reviewers also report lag, freezes, and crashes, and it's weak on behavioral interviews. Coding-only. Verify pricing on their site.

5. Cluely: the biggest brand, with the biggest asterisks

Cluely (cluely.com) is the most recognizable name here: a real-time overlay for macOS, Windows, and iOS, with broad coverage across sales, meetings, and interviews, CRM features, and a16z backing.

Strength: it's the broadest, best-funded product in the category.

Attributed weaknesses: the undetectable capability is reportedly gated to a "Pro + Undetectability" tier around $149.99/month, on top of a ~$20/month Pro plan. Trustpilot sits around 1.8/5, dominated by billing, refund, and cancellation complaints. Independent tests measured 5–10+ seconds of latency against an advertised ~300ms, and reviewers report it being flagged within seconds on CoderPad and HackerRank. In March 2026, founder Roy Lee told TechCrunch that a prior $7M ARR figure was fabricated. Verify pricing on their site.

If you want to get better at coding

Not every reader wants a copilot. If your goal is to pass coding rounds on your own merit and keep the skill afterward, legitimate prep is cheaper and lower-risk:

• LeetCode Premium (~$13/month) for the problem set, company tags, and solutions.
• NeetCode (~$10/month) for structured pattern-based courses and roadmaps.

Both cost a fraction of LeetCode Wizard's reported ~$58/month, and neither carries disqualification risk.

How they compare

Prices change often. Confirm current numbers on each vendor's site before you buy.

A word on responsible use

Whatever you choose, use it within the rules of the meeting, call, or interview, and respect recording-consent laws. Employer policies vary widely. Some companies now allow AI in interviews, others ban it outright. Assistly is built to help you be prepared and present, and you control your data: delete sessions and notes anytime.

Bottom line

If you only ever face algorithm puzzles and accept the second-phone workaround, LeetCode Wizard does what it says. Most interviews, and every meeting and sales call, involve far more conversation than code. Assistly covers all of it, with OS-level capture exclusion, a renamable app, personas that sound like you, and flat $14.99 pricing with no detectability upcharge.
