Comparison
HackOffer vs Interviews.chat
Two copilots that both run in a browser, and only one with a desktop panel a screen share cannot capture. Compare what each latency figure measures, and what the two ladders actually cost.
The short version
Interviews.chat is a careful product and an unusually easy one to check. The whole price ladder is on the page, the free tier needs no card, the audio position is stated in one sentence, and nothing on the site claims to be undetectable. That last restraint is rare in this category and it deserves saying out loud: what they describe is what a browser copilot can do.
The gap between the two is architectural rather than a matter of features. Theirs runs where your interviewer can see it the moment you share a screen; ours, in the desktop app, is a translucent always-on-top window the operating system leaves out of the capture, on every plan including the free half hour, with the limit stated in the same words on the site and in the terms.
So the decision is fairly clean. If the screen will be shared, the interview is not in English, or you want to know exactly what the latency figure measures, HackOffer is the tool built for it — with a whiteboard for design rounds and an AI mock interview to rehearse with besides. A machine you cannot install software on no longer decides it: a HackOffer session runs in a browser tab as well — share the meeting tab rather than the screen — or on a phone beside the laptop.

Every cell about Interviews.chat is taken from their own public pages and checked in September 2026; where a figure comes from somewhere else, the cell says where. A question their pages do not answer is left out of the table rather than guessed at.
Interviews.chat is a trademark of its owner. This page is an independent comparison written by HackOffer; it is not endorsed by, affiliated with or reviewed by Interviews.chat.
A browser tab is part of the screen you share
Interviews.chat makes no invisibility claim, and that is to its credit. What the site says is that the copilot does not join the meeting and notifies no one, that it monitors the conversation quietly in the background — all of which is true of a browser tab, and none of which is a statement about screen sharing. A tab cannot make one. When you share a screen, the compositor hands over that screen’s pixels and everything drawn on them goes too. Sharing a single window instead does keep the rest out of the capture, right up until the round asks for the whole screen, which coding rounds usually do.
HackOffer’s panel is a separate always-on-top window that the operating system is told to leave out of any capture: on macOS the window’s sharing type is set to none, on Windows it is the capture-exclusion flag. It is one call on each platform, it covers screen shares, screenshots and recordings alike, and it is on by default here on every plan — the free thirty minutes included. There is no tier where the panel is visible and a dearer one where it is not. A HackOffer session in a browser tab has no such flag and is as visible as any other tab, which is why the desktop app is the one we recommend on a computer, and why a phone beside the laptop — nothing on the shared screen at all — is the other way round it.
We also say where it stops, in the same words on the site and in the terms: it hides pixels, not the process. A phone camera pointed at your monitor still sees the panel, and proctoring software that enumerates running processes still finds the app. Treat it as private, not as undetectable. The one caution Interviews.chat gives — do not read a suggestion out word for word — is good advice we would repeat; it just answers a different question from the one about what is on the shared screen.
Two ways of keeping a call private, and the difference between them
Interviews.chat states its position plainly: it does not store any audio or video, they are processed in real time and exist only for the duration of the browser session. That is a real commitment and it is worth more than the silence most of this category offers. Nothing is retained, so there is nothing to hand over later and nothing to leak.
The site does not say how the audio is captured — whether from the system mixer or from a microphone listening to your speakers. Those two produce noticeably different transcripts of the same interviewer, and the difference is worth knowing before the call rather than during it.
In HackOffer the question is detected on your own machine. Capture is the system mixer, before the sound reaches your speakers, so headphones make no difference and nothing joins the meeting. What we keep afterwards is the finalized transcript, each detected question and the answer written for it, for thirty days — kept so you can read the call back, and deletable sooner whenever you want.
Credits, quarters, and what a free tier is for
Their ladder is published in full and easy to read: Starter at $19 a month for 1,000 credits, where one credit is a minute of copilot or a single suggestion; Booster at $29 a month with unlimited time and suggestions; Pro at $69 a quarter, also unlimited. Signing up gives you 30 credits with no card. That quarter comes to roughly $23 a month, below any plan of ours.
Ours is $49 a week, $89 a month or $349 a year, all three on the pricing page before you sign up, and the paid plan is not metered — no minutes, no credits, nothing counting down while you decide whether to ask a follow-up. The week is there because interviews arrive in clusters: two rounds in five days and then nothing for a month is a normal shape, and buying a month to cover it is not. The first week or month is half price.
Free here is thirty minutes of session time, once per account, no card, unmetered inside the half hour — the whole product, both models, as many documents as you like. It exists to answer one question before you pay: whether reading an answer while someone is talking to you actually works for you. It takes the place of a refund promise, as the refunds page says: once a payment is made, it is not refunded. Interviews.chat publishes no refund policy anywhere on its site. Cancelling is self-serve on both sides, and on both sides access runs to the end of the cycle you paid for.
Why people move from Interviews.chat to HackOffer
The panel is excluded from capture by the operating system, on every plan and on the free half hour, and we write down where that stops — it hides pixels, not the process. Interviews.chat claims no screen-share invisibility at all; its guidance is that you should not read a suggestion out word for word.
A latency figure with a definition attached: ~1.3 s, end of the spoken question to the first word on the panel, stated as the design budget the pipeline is built to rather than a percentile from a dashboard. Theirs is an asterisked “under 1 s” that never says what is being timed.
Eighteen interface languages against one, two models you can switch between on every plan including the free one, answer length you set, and your resume, the job description and your notes in every request whole — no chunking, no embeddings, no retrieval step choosing a paragraph for you.
Interviews.chat’s extension can read a whiteboard tab; it does not put anything on one. Design mode keeps a whiteboard of its own — a brief, an architecture diagram, a data model — redrawn only where the last question changed it, and copied out as Mermaid for the board you are actually sharing.
What Interviews.chat does not do
- No screen-share invisibility, and none claimed: the copilot runs in a browser tab or a window on the desktop you share, and the only guidance offered is behavioural — do not read a suggestion out word for word.
- No operating systems are stated anywhere on the site, so what their desktop app requires is something you discover when you install it.
- The latency figure carries an asterisk and no definition: under 1 second, varying with the model, your location and network conditions, with no statement of what is being timed.
- No refund policy is published anywhere on the site. Cancelling is self-serve and access runs to the end of the cycle, which is the same as ours, but there is nothing in writing about money already taken.
- Starter is metered in credits, where one credit is a minute of copilot or a single suggestion, so a long round and an inquisitive one both draw down the same 1,000. The interface is English only.
Choose HackOffer if
- Your screen will be shared at some point in the round, and you want the panel left out of the capture rather than merely quiet.
- You want a latency figure that says what it measures: ~1.3 s from the end of the spoken question to the first word on the panel.
- The interview is not in English, or you would rather read the interface in your own language.
- There is a coding task on the screen, and you want one shortcut to capture it and working code back for that exact task.
Choose Interviews.chat if
- You want unlimited use for $69 a quarter and will not be sharing a screen.
- You want an unlimited plan by the month for $29.
- The interview is in a language outside our nineteen; they list 40.
Three questions that settle it
Will you share your screen at any point?
If you will, the two products stop being comparable on this point. Interviews.chat runs in a browser tab or a window on the same desktop you are handing over, and it makes no claim otherwise. HackOffer’s panel in the desktop app is marked at the operating-system level as excluded from capture, on every plan including the free half hour.
Is the monthly price the number that decides this?
Then weigh what each price buys. Interviews.chat’s unlimited plans are $29 a month or $69 a quarter, below our $89 a month, for a copilot that makes no claim to stay out of a screen share, in an English-only interface, with no refund policy published. HackOffer’s price buys a desktop panel kept out of the capture on every plan, an answer timed at about 1.3 seconds, design mode, an AI mock interview, and a single week for $49 when the interviews come in a cluster.
Can you install software on the machine you will interview on?
If you cannot, both of them still run. Interviews.chat is a web app, and a HackOffer session runs in Chrome or Edge on any computer, a locked-down work laptop or Linux included, or on a phone beside the laptop. What an install buys is the screen share: a browser tab of ours is as visible to a full-screen share as theirs, so share the meeting tab alone, while our desktop app, on macOS 13 or newer and Windows 10 or newer, keeps its panel out of the capture.
