A homework-writing YouTube channel built a free plugin for Pakistani online university students: 461 users in a month. The plugin makes no money itself; it drives traffic to the homework business.

KST Learning VU Assistant is a Chrome extension that runs only on Pakistan's Virtual University (VU) learning system. It shows grades, calculates GPA and maps degree paths. It launched in Oct 4, and daily users went from 283 in Nov 1 to 461 by 6. Its maker isn't a tool developer but a studio that writes assignments, takes quizzes and watches lectures for VU students. The plugin is free, and the studio makes its money from the YouTube channel and the homework business. Below: how it got users, why it built a plugin, and what you can learn from it.

A "homework answer" video with 14k views

Early on Oct 30, YouTube channel KST Learning posted a video titled "CS304 Assignment 1 Solution Fall 2026". CS304 is an object-oriented programming course in VU's computer science program. The video walks through the answers to the first assignment, and its description says "100% correct" and "get a full score of 20/20, won't be flagged for plagiarism". By Nov 6, it had 13,778 views.

The first link in the description is this plugin, labeled "Assignments, Quiz, GDB" (GDB is VU's discussion-board assignment). The second line is the studio's WhatsApp channel. Below that are a "paid service contact number" and five rules in Urdu under "paid service rules". The first rule: the assignment is submitted by us, logging into your LMS ourselves.

From Oct 27 to Nov 6, the channel posted 29 such "assignment answer" videos, each with the plugin link in the description. Individual views ranged from 1 thousand to 14k, about 160k in total (YouTube, 11-06). The plugin gained 178 users between Nov 2 and 6, right in the middle of this wave of videos (Chrome Web Store, 11-06).

What it is

VU is Pakistan's public distance-learning university. All its courses run in one online learning management system (LMS). 139,692 students sat exams last semester (VU website). The school built its own proctoring plugin, "VU Quiz Firewall", which blocks copying and limits tab switching during quizzes, and has 80k users (Chrome Web Store, 11-06). Around it grew a ring of "bypass proctoring" plugins, and the top two each have 20k users.

KST's plugin doesn't take that route. The word "bypass" appears nowhere in its name or description. The store listing reads:

The last line is vague. In practice it means marking online lectures as watched in one click and copying quiz questions. Competing plugins put that in the title as the selling point; this one puts it at the end. The store page also says the homepage banner and some quick links lead to KST Learning's services, including paid ones.

Where users came from: entirely its own channel

The KST Learning channel opened 2022 years ago. It has 29.9k subscribers, 1,681 videos and 11.3M total views (YouTube, 11-06). It normally posts short explainers for VU courses, and its most-watched videos have hundreds of thousands of views. It is a place VU students already trust.

After the plugin launched, the channel posted three tutorials: an Urdu installation demo on Oct 6 (3,071 views), a usage tutorial on Oct 13 (1,075 views), and an update note on Oct 17 (1,014 views). Then homework season began, and answer videos kept coming, each with the link. 34 of the last 50 videos included it (YouTube, 11-06).

Beyond that, the studio website published one blog post about the plugin (133 views). Nobody on X mentions it, no media has written about it, and no paid ads have been spotted.

The comments under the tutorials show why students install it:

"Super useful, all my courses show as watched in a minute, it used to take ages." — 10-13

"I'm a third-year VU CS student. Your courses have always helped, and this plugin is a lifesaver. I wish it had existed in my first semester." — 10-13

The school has already issued a ban

Oct 16, VU sent students a notice. Roughly, it said: don't use Chrome extensions, third-party tools, or paid services claiming to help with the LMS; they can leak account and personal data; anyone using them to get around LMS controls or gain improper academic help will face administrative and disciplinary action under university rules; remove such extensions immediately. (KST reposted the original in its video comments; VU-linked Facebook and Instagram accounts also shared it.)

The notice named extensions and paid ghostwriting, exactly the two things KST sells. In the comments, several students came asking "does it still work?" and "will accounts get banned?" The channel replied: "No ban, KST's extension is 100% safe" and "You can use it." One student asked the more pointed question: "You also run LMS management services. Will the school come after you?" The channel answered: "The school won't do that. Nobody knows what happens later."

Students kept installing it, and users grew 60% after the ban. But this shows the extension could be targeted by the school at any time, or taken down after a report.

Where the money comes from

The extension charges nothing, and the store has no in-app purchases. The money sits outside it. KST's website advertises "LMS management" at ₨2,000 per course and ₨12,000 per semester (about $43, estimated), plus ghostwritten assignments, proxy quizzes and proxy final projects, all ordered via WhatsApp. The studio says it has been doing this for 5+ years. Revenue is not public.

The extension serves this business in two ways. First, every time a student opens the LMS, the homepage banner links to the paid services, right where the assignment deadline is. Second, it works as a multi-account vault: an ordinary student has one account, but a proxy studio logging in and submitting for many students needs "one master password for many VU accounts" (inferred). So some of the 461 users may be the studio's own people.

What it adds compared with similar tools

(Chrome Web Store, 11-06)

Rivals chase volume by searching the store for "bypass". KST relies on its own channel. It has about one-fortieth the users of the top player, and the difference is that it sits on a business that makes money; the extension is just the entry point. Several small extensions grew in the same period. The start of term and assignment season lifted the whole niche, and KST's 5-day +63% was the fastest.

If it were you

Grade C. Worth studying for the playbook, not worth copying. The extension itself is small. Users come from a channel built over four years, and the money comes from ghostwriting, which the school has explicitly banned.

Good fit for: people who already have traffic and a paid service in a vertical: creators making tutorials for a specific exam, platform or profession, or small studios that sell services. What you're missing isn't a product, it's an entry point that people touch every day.

Bad fit for: developers without their own audience. The VU niche already has five or six similar extensions with 10,000+ users that win through store search. A new one would have neither their head start nor KST's channel. It's also a bad fit for anyone unwilling to touch academic dishonesty and account proxying: the money is there, but the school's ban could escalate at any time.

How to do it: find a place where a crowd opens the same web page every day: a university learning system, an exam registration site, a government service portal, a seller back office. Build a free extension that fixes the page's worst pain points (confusing grades, unclear progress, convoluted steps), and put your paid service entry on the homepage. Lead with compliant, everyday features, and keep sensitive functions out of the name.

How to get users: plug it into your own content. KST followed the semester rhythm, posting heavily in the two weeks before deadlines when demand peaked. Every video description opened with the extension link, followed by a native-language install tutorial.

When to move: there's no fixed window. Follow the peak of your audience. For school-related products, it's right before the first assignment deadline after term starts.

Signs you've misread it: (1) the KST extension is removed from the Chrome Web Store, or VU starts banning accounts that used it, which would show that a compliance veneer can't protect a grey-area business; (2) the channel keeps posting links through the mid-term assignment cycle but extension users stop growing, which would show it only brings one-off curiosity from viewers and can't retain them; (3) the reverse: users pass 1,000, reviews rise noticeably, and the channel gets no bigger promotion, which would show the grades and GPA features retain users on their own and this playbook is more replicable than it looks.
