What Interview Coder is, and why people look for alternatives
Interview Coder is a desktop app for Windows and Mac built around live coding rounds. Per its homepage, it reads the coding problem and transcribes the interviewer's audio, then produces a solution. It was built by Chungin "Roy" Lee and Neel Shanmugam, the founders who rebranded it to Cluely in April 2025; both sites still sell products separately in 2026.
As of October 2026 it has two paid plans:
- Monthly Pro: $299/mo with 1,000 usage credits a month.
- Lifetime Pro: $799 one-time.
People look for alternatives for reasons you can check on its own site:
- No free AI. The free download needs a subscription to unlock AI features, so you can't judge answer quality before paying.
- No refunds. Its refund policy says no purchase is refundable, and its terms say subscriptions auto-renew unless you give written notice at least 30 days before renewal (as of October 2026).
- Coding only. There is no practice mode and nothing for behavioral, recruiter or system design rounds, which are part of most loops.
- Its main pitch is concealment, which is a risk wherever an employer doesn't allow AI help.

The 8 best Interview Coder alternatives, reviewed
1. CoPilot Interview: best for daily coding practice across the whole loop
CoPilot Interview is a desktop app for Windows 10+ and macOS 12+ with four modes: Mock Interview, Candidate Mode (live help), Interviewer Mode for hiring managers, and a Resume Builder. It runs as its own window beside Zoom, Microsoft Teams and Google Meet.
Strengths:
- Mock Interview builds a session from your résumé and the job description. You choose the level, 3, 5 or 8 questions, the mix (behavioral, technical, system design, coding), your coding language and an optional focus. Coding questions never auto-submit, so you can think in silence.
- Each spoken answer is scored out of 10 with what to fix and a model answer, then you get a report card.
- Coding mode gives complete code in your chosen language, its complexity and an example run, which is useful for checking your own solution after practice.
- A free browser mock interview with 113 real questions across 9 tracks, including coding, system design, SQL and data science.
- Free every day (15 minutes, all four modes, no card), then Standard at $14.99/mo (sale; regular $19.99) with 60-minute sessions and up to 100 minutes a day, or hour packs from $5.99. There's a 14-day money-back guarantee on a first subscription payment if you used under 30 minutes of live session time.
Limits: no lifetime licence, which is a real advantage Interview Coder has. No Linux build, and free sessions stop at 15 minutes. CoPilot Interview isn't affiliated with Microsoft Copilot or GitHub Copilot.
Follow the rules of the employer or assessment you're in — many people use it only to practice, which works on the free plan.
2. Interview Solver: best coding-focused prep platform
Interview Solver describes itself as a platform for coding and technical interview prep, with guided practice, interview resources and a desktop copilot for macOS and Windows, per its site (October 2026).
Strengths: built for technical rounds, a free tier, and pricing from $59/mo with a 3-month "Interview Cycle" plan, a fifth of Interview Coder's monthly price.
Limits: it's centered on technical rounds, and its site doesn't list every plan's price on the homepage, so check its pricing before buying. See CoPilot Interview vs Interview Solver.
3. interviewing.io: best for mock interviews with senior engineers
interviewing.io sells anonymous mock interviews with senior, staff and principal engineers, covering algorithms, system design, machine learning and behavioral rounds.
Strengths: the most realistic technical practice here, a free AI Interviewer for coding and system design, and a full refund if you're unhappy, per its FAQ (October 2026).
Limits: human mocks start at $179 each, so it's for a few targeted sessions before an onsite, not daily reps. See our interviewing.io review.
4. Aced (formerly Exponent): best for system design courses and peer mocks
Exponent renamed itself Aced in August 2026. It combines courses, a question bank, peer mock interviews, AI practice and paid coaching.
Strengths: the free Basic plan includes 5 peer mocks a month. Pro is $79/mo or $149 a year; Expert, with AI mock interviews, is $99/mo or $249 a year, per its pricing (October 2026). It's strong for system design, which Interview Coder doesn't touch.
Limits: month to month it's steep for a short search, and 1:1 coaching costs extra ($249 a session). See our Exponent (Aced) review.
5. LockedIn AI: best coding assistant with an editor extension
LockedIn AI has a coding assistant alongside its interview copilot, plus a VS Code and Cursor extension, desktop apps for Windows 10+ and macOS 13.1+, a web app, and iOS and Android apps, per its site.
Strengths: covers coding and the other rounds, a free plan with no card, and credits that never expire.
Limits: free sessions stop at 5 minutes, and unlimited is $109.98/mo month to month (first month $43.99) or $79.98/mo billed every 3 months (first payment $31.99/mo) (as of October 2026). See Interview Coder vs LockedIn AI.
6. Final Round AI: best broad paid suite
Final Round AI is a desktop app for Windows and macOS 14.4+ with coding help, practice interviews and automatic AI debriefs on its Pro plan.
Strengths: covers coding, behavioral and other rounds in one account, with a free plan for résumé materials and job-description prep.
Limits: its pricing page says there is no free trial of live sessions; Pro is $150/mo month to month or $25/mo billed annually (October 2026). See Final Round AI vs Interview Coder.
7. Parakeet AI: best for company question banks and pay-per-hour mocks
Parakeet AI sells credits that cover calls, mock interviews and a company question bank, per its pricing page (October 2026).
Strengths: one credit ($38) covers about an hour of mock interviews or unlocks one company's questions in its question bank; a 15-credit pack works out to $11.80 a credit. Your first mock interview is free.
Limits: unlimited is $149.90/mo month to month, and the free session is 10 minutes. See Interview Coder vs Parakeet AI.
8. Cluely: Interview Coder's sibling, for general meetings
Cluely comes from the same founders. It's a general meeting assistant for calls, sales and interviews, on Mac, Windows and iOS.
Strengths: a free Starter plan and Pro at $19.99/mo ($11.99/mo billed annually), per its pricing page (October 2026), far below Interview Coder.
Limits: it isn't tuned for coding rounds, and its top tier ($149.99/mo) adds one more feature on top of Pro. See Interview Coder vs Cluely.
Which rounds each Interview Coder alternative covers
A typical software engineering loop has a recruiter screen, one or more coding rounds, often system design, and a behavioral round. Interview Coder covers only the coding part.
| Tool | Coding rounds | Other rounds it publishes support for | Practice mode |
|---|---|---|---|
| CoPilot Interview | Yes | System design, behavioral, recruiter screens | Best choice: Mock Interview scored out of 10, on the free plan |
| Interview Coder | Yes | None | None |
| Interview Solver | Yes | System design and other technical rounds | Guided practice |
| interviewing.io | Yes | System design, machine learning, behavioral | Human mocks with feedback; free AI Interviewer |
| Aced (formerly Exponent) | Yes | System design, product management and other tech roles | Peer mocks; AI mocks on Expert |
| LockedIn AI | Yes (coding assistant) | General interview rounds | Mock interviews |
| Final Round AI | Yes | General interview rounds | Practice interviews on Pro |
| Parakeet AI | Yes | General interview rounds; company question bank | Mock interviews by credit |
A practice-first way to prepare for coding interviews
No tool replaces knowing the patterns. This is the order we suggest, using free tools first:
- Pick one problem list and finish it. Our NeetCode 150 vs Blind 75 vs LeetCode 75 comparison helps you choose.
- Review patterns and complexity with the coding interview cheat sheet and the Big-O complexity visualizer.
- Practice talking while you code. Run a Mock Interview with coding questions in your language and explain your approach out loud before writing code.
- Add system design and behavioral reps, using the system design cheat sheet and the same Mock Interview with a different mix.
- Book one or two human mocks (interviewing.io or Aced peer mocks) in the final week or two.
Online assessments and take-home tests are part of many loops. Take the assessment yourself and follow the employer's rules — use CoPilot Interview to practice beforehand.
How we chose these Interview Coder alternatives
We did not run paid hands-on tests of every product. We compared what each vendor publishes on its own site (pricing, homepage, FAQ and refund terms), checked in October 2026, and left out vendor user counts and success claims because they aren't independently audited.
The criteria:
- Whether you can try the AI or practice for free before paying.
- Cost over a 4 to 8 week search, and refund terms.
- Coverage beyond coding: system design and behavioral rounds.
- Practice features, such as scored mock interviews or human feedback.
- Platforms.
