The 5 best LeetCode Wizard alternatives in 2026

By The Assistly team · June 4, 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. But 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. So let's start there, then get into the actual 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 — exactly the kind of "reading eyes" tell that interviewers watch for.
• It's expensive versus legitimately learning. Reported pricing is around €49/month (~$58). For comparison, LeetCode Premium runs about $13/month and NeetCode about $10/month — and those actually teach you the patterns.
• Real disqualification risk. On a proctored coding platform, a tool whose hide mode is admittedly beatable is a genuine liability.

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

1. Assistly — best overall, and not just for coding

We make Assistly, so treat this as a pitch. But the core difference is structural, not promotional: LeetCode Wizard is a code-puzzle wrapper, while Assistly is a real-time copilot for the whole conversation — 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 a real, 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 & system-design modes — plus everything else. Assistly has assist modes built for technical rounds, so it covers LeetCode-style and system-design questions too — not only the behavioral side.
• Built for talking, not just 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 and simple. Free gives you 5 sessions a month (45 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 — there's no separate "undetectability" upcharge.

A fair 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 — it's engineering, not magic. 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.

Genuine 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 — 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.

Genuine 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 — powerful 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.

Genuine 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.

Genuine 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 actually want to get better at coding

Not every reader wants a copilot. If your real goal is to pass coding rounds on your own merit — and to 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. But 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.
