StealthCoder is a desktop app that reads a coding problem from your screen and returns a solution during a live interview or online assessment. People searching for it usually want the price, whether the free trial is really free, and how it compares with other tools. This review uses StealthCoder's own website as of October 11, 2026. We make a competing product, YesToTheOffer, so we say where StealthCoder fits and where it doesn't.
The short version
| What it is | A Mac and Windows app that gives AI answers for coding and system design interviews |
| Price | $40 a month, or $180 a year (shown as $15 a month) |
| Free trial | 7 days, card required, renews at $40 a month unless you cancel |
| Refunds | The site says refunds are not available |
| Platforms | Mac (Intel and Apple Silicon) and Windows |
| Good for | Engineers who want a tool for coding and system design rounds only |
| Less good for | Behavioral interviews, short job searches, and anyone who wants to pay only for what they use |
What StealthCoder does
From the product's website:
- It's a desktop app. The site says it is not a browser extension and doesn't run a local server.
- You press a shortcut (Ctrl + Alt + 1), and it captures the problem on your screen and sends it to an AI model.
- It returns code, an explanation, and time and space complexity. The site claims a full solution in under 2 seconds.
- A second mode called StealthDesign covers system design interviews. Both modes are in the same subscription.
- The subscription includes the AI usage, so you don't need your own ChatGPT Plus account or API key.
- The site names LeetCode, CoderPad, HackerRank, and CodeSignal, and says the overlay doesn't appear in Zoom, Google Meet, or Teams screen shares.
On which AI model it uses, the site isn't consistent. The pricing section says "powered by the latest Claude models," while the FAQ says the company doesn't publish provider or model names.
The site also has a public database of reported interview questions: 469 companies, 1,923 problems, and 71 algorithm patterns, by its own count. That part is useful for preparation and doesn't require the app. It also lists what it calls leaked online assessments. Using leaked test content can break the terms you agree to when you take an assessment, so we'd leave that section alone.
What StealthCoder costs
| Plan | Price | Details |
|---|---|---|
| Free trial | $0 for 7 days | Card required. Renews at $40 a month. Full access, including system design mode |
| Monthly Pro | $40 a month | No annual commitment. Unlimited monthly usage |
| Annual Pro | $180 a year | Shown as $15 a month. Same features as monthly |
Both paid plans cover Mac and Windows and include priority support.
The annual plan costs the same as four and a half months of the monthly plan. If your job search will last five months or more, annual is cheaper. If you expect to be done in two or three months, monthly costs $80 to $120.
Is StealthCoder free?
There's a 7-day free trial, and it needs a card. The FAQ says you won't be charged if you cancel before the trial ends, and that you can cancel from your dashboard in one click. If you forget, it renews at $40 a month. There's no permanent free plan.
The refund policy
In a note about Mac screen sharing, the site tells users to test the app before subscribing and states that refunds are not available. So the trial is the only way to check that it works on your setup before you pay. Set a reminder for day six.
Does it stay hidden?
The site's main claim is that the overlay is invisible during screen sharing. Its own fine print is more careful than its headline:
- A note says that on a small number of Mac setups, some browser-based screen sharing apps may show the overlay when you share your entire screen. It says window sharing and Zoom with advanced capture work as expected.
- The FAQ says proctoring tools can see activity inside their own page, such as tab switches, paste events, and timing.
- Asked whether it can guarantee you won't get caught, the FAQ answers no, and says no tool can guarantee outcomes.
Hidden from a screen share also isn't the same as hidden from the interviewer. Long pauses, eyes moving to the same spot, and a perfect solution you can't explain are what people notice. We cover this in is an AI interview assistant really undetectable.
Is StealthCoder worth it?
| Your situation | What it costs |
|---|---|
| Trying it for a week | $0 if you cancel in time |
| One or two months of interviews | $40 to $80 |
| A long search of five months or more | $180 for the year |
It's a narrow tool. The site describes coding and system design help and nothing else. It doesn't list help with "tell me about yourself," behavioral rounds, or questions about your resume, and it doesn't mention transcribing the interviewer. If your interviews are mostly algorithm rounds, that focus may be fine. If they're mixed, you'll need something else for the other half.

StealthCoder alternatives
If you're comparing coding interview tools, these reviews use each product's own pricing page:
Check the rules first
Employers decide whether AI tools are allowed, and many ban them in live coding rounds and online assessments. Some make you confirm that in writing before a test. A tool that hides from screen sharing doesn't change the rules. If you're found out, you can lose the offer and be flagged by the company.
The safest uses of any coding assistant are practice and review. Solve problems aloud, compare your approach with the tool's, and read your transcript to find where your explanation was thin. Our coding interview assistant guide covers a preparation routine, and the CoderPad sandbox is a free place to practice in the editor many employers use.
Try YesToTheOffer with 30 free minutes
Pay only for the minutes you use. Live transcription, answers from your resume, coding help from screenshots, and a review after. No subscription.
