Is Stealth Interview a Sensei AI alternative?

For technical rounds, yes: it is built for the code, not the conversation. Stealth Interview is a macOS and Windows desktop app that reads the coding problem on your screen and returns a working solution with a step-by-step explanation and its time and space complexity, transcribes interviewer audio, and stays invisible to screen sharing. It has no resume builder and no browser version.

How much does each product cost?

Stealth Interview is $49 a month for Starter, $150 for six months for Premium and $250 for a year for Hunter, with unlimited usage on all three. Sensei AI's home page listed Free at $0 and PRO at $89 per month or $24 per month billed annually when we read it in August 2026.

Do I have to install anything?

Yes. Stealth Interview is a native application for macOS and Windows. If you cannot install software on the machine you interview from, a browser-based product is the better fit.

Does it help with behavioural questions?

It transcribes the interviewer in real time, so a spoken question reaches the assistant, but the product is built around technical problems: reading a coding question on screen and returning a solution with its complexity.

Which models does Stealth Interview use?

Starter includes GPT-6 Luna and GPT-6.1 Terra. Premium and Hunter add GPT-6.1 Sol, GPT-6 Astra, Claude Sonnet 5.5 and Claude Opus 5.5.

Sensei AI Alternative: Tone Won't Compile

Sensei AI's pages (August 2026) describe answers tuned for tone and formality, in a browser tab. In a coding round the interviewer reads your code. Stealth Interview writes it, explains it and states its complexity.

What Sensei AI actually is

Sensei AI's home page (August 2026) describes a real-time interview copilot, delivered as a web application at app.senseicopilot.com.

Sensei AI is a real-time interview copilot that runs as a web application. Its home page (August 2026) says it integrates with almost all video conferencing platforms and names Zoom, Microsoft Teams and Google Meet.

It leads with the conversation. The home page describes speech recognition with under a second of latency, answers personalised to your tone, word choice, timing and level of formality, resume and personal-story upload, and support for 30+ languages.

Its feature list also includes a Coding Copilot for technical questions, an AI Resume Builder, an AI Story Editor, a full customisation suite and an AI Playground. Pricing is published on the same page: Free at $0 with fifteen-minute copilot sessions, and PRO at $89 per month or $24 per month billed annually.

Everything about Sensei AI on this page was read on its own site (opens in a new tab) in August 2026. Where its pages are silent we say so; we don't test rivals' software or guess what it does.

Where it costs you in the round

The Coding Copilot is one line on a feature list built around the conversation: resume builder, story editor, tone matching, personalisation.
It is a web app. No install, and no window of its own outside the browser either.
The pages we read describe no desktop build, so there is no native app to put beside ours.
The free tier ends a copilot session at fifteen minutes. A typical technical round runs well past that.

Credit where it's due

Pricing is published plainly, including the annual rate — more than most products in this category do.
The annual PRO rate is among the lowest published in this comparison.
Personalisation from an uploaded resume and personal stories is aimed squarely at behavioural rounds.
Nothing to install: it runs at app.senseicopilot.com.
30+ languages, and a free tier with fifteen-minute sessions to try it.

How the two are built

This is a browser tab against a native window, and the trade is real on both sides.

A web application inherits the browser's reach: any machine with a modern browser can run it, including machines you have no rights to install on, which is a genuinely common situation for candidates interviewing from a current employer's laptop. It also inherits the browser's boundaries — a page runs inside a tab, and everything it can draw is drawn inside that tab.

A native desktop application inherits the opposite set. It has to be installed, which rules out locked-down hardware, and it must be built and shipped separately for macOS and Windows. In exchange it draws its own window outside the browser, and that window is excluded from screen-sharing capture.

The third difference is what each product is tuned to emit. Sensei AI's published feature set is oriented around speaking well: latency under a second, tone, formality, timing. Stealth Interview is oriented around being correct in writing: a solution, an explanation, and the complexity you will be asked to justify. Two different definitions of a good answer.

What the platforms actually document

Live video interviews and proctored assessments are so different that a single answer to is it detectable cannot be right for both. On a Zoom, Teams or Google Meet call, there is no scanning software: an interviewer sees your shared screen and hears you talk.

Proctored assessments are where documented enforcement lives. HackerRank's knowledge base (August 2026) describes Secure Mode as a controlled browser environment that enforces full screen, blocks copy and paste, prevents multiple monitors and flags tab switches, and Proctor Mode as adding screenshot analysis, plagiarism detection and webcam anomaly detection. Its Desktop App Mode requires installing an application that blocks and closes other programs, prevents screen sharing and screenshots, checks for screen mirroring and multiple monitors, and refuses to run on a virtual machine.

Those documents are public and worth ten minutes of your time before an assessment. They also make the honest limit of every product on this page clear: in a mode where the platform closes other applications, the answer is preparation, not procurement.

The test is in a tab. The answer isn't.

Unless Desktop App Mode is on, a HackerRank test is a web page. Stealth Interview runs outside it, in a desktop window set to be excluded from screen capture.

It doesn't change what the webcam sees, the editor's own record of pastes and typing, or a browser noticing focus leave the test, and we haven't tested every browser and OS version a test runs on. Desktop App Mode is HackerRank's own native app, documented to close other programs: plan on Stealth Interview not running beside it, and prepare with the binary search pattern instead.

What each HackerRank mode records

The coding round is the entire product

No resume builder, no story editor, no tone matching. The app reads the problem on screen and returns a solution you can run, with a step-by-step explanation and its time and space complexity.

A native window on macOS and Windows
Stealth Interview is a desktop application, not a browser tab, and it is not captured by screen-sharing or meeting software.
Unlimited usage, no session clock
Starter, Premium and Hunter all include unlimited usage; there is no fifteen-minute or ninety-minute ceiling to watch.
Interviewer audio and screen together
Live transcription of interviewer audio means a spoken follow-up is answered against the problem you already captured.
Model choice, stated per plan
GPT-6 Luna and GPT-6.1 Terra on Starter; GPT-6.1 Sol, GPT-6 Astra, Claude Sonnet 5.5 and Claude Opus 5.5 on Premium and Hunter.

When Sensei AI is the better buy

Your interviews are mostly conversation: Tone matching, personal-story editing and resume-driven personalisation are built for the round where someone asks you to describe a conflict with a teammate. Stealth Interview has nothing for that: it reads coding problems and explains solutions.
Price is the deciding factor: Per Sensei AI's home page (August 2026), PRO is $89 per month or $24 per month billed annually. Our Hunter plan is $250 for a year. Do that arithmetic against your own search length before you buy anything — on a long, low-intensity search, theirs may well come out ahead.
You cannot install software: A web application runs on a managed laptop where you have no administrator rights. An installed desktop app does not. That constraint decides the question on its own.
