Fair exams. Graded instantly. No surprises.
Exam Cover Browser is a secure desktop app for proctored tests. It runs the student's code, scores their writing, and evaluates their spoken answers — right on the device. Students get instant results, you save on server costs, and exam integrity stays watertight.
One browser. Three kinds of answers, graded instantly.
Everything happens on the student's machine — no waiting for a server to come back, no question of whether the grading is consistent.
Coding questions
Runs the student's code against the test cases in milliseconds — the same way your students see it on the web.
- 6 languages: C, C++, Java, JavaScript, Python, C#
- Visible + hidden test cases, scored independently
- Compile and runtime errors surfaced in plain English
- Per-test timeouts so an infinite loop can't hang the exam
Writing questions
Scores essays the moment the student stops typing — clarity, grammar and originality, all on the device.
- Spelling, grammar and vocabulary depth
- Readability and structure
- Coherence — is the essay actually on topic
- AI-writing suspicion flag (drafted with ChatGPT etc.)
Speaking questions
Records the student's spoken answer, transcribes it offline, and scores both delivery and content.
- Accurate transcription that works offline
- Pace, filler-words and overall fluency
- Pronunciation scoring per word
- Answer relevance scored against the reference answer
Built for placement cells.
No more flaky grading
Coding test cases run on a fresh, identical environment for every student. Same code, same result, every time.
Cut your server bill
The heavy lifting — compilers, speech transcription, writing analysis — happens on the student's laptop, not your cloud.
Defensible integrity
Every focus loss, app switch, face mismatch and tab change is captured and rolled into one number you can show to recruiters.
The four ways students cheat today — closed.
The exam-cheat playbook has changed. Today's students don't sneak chits — they install browser extensions, share their screen, run a second browser, or project the exam onto a TV. Exam Cover Browser was built to catch all four.
No AI exam-helper extensions
A whole industry has popped up around browser extensions designed for one thing — solving the exam question in front of you. We detect and refuse to launch the exam if any of them are installed (Honorlock-killers, AI tutors, paste-helpers, code-bots). The student is told to uninstall and try again — no quiet pass-through.
No screen sharing
Teams, AnyDesk, Zoom, TeamViewer, Chrome Remote Desktop, Parsec — every common screen-sharing or remote-control app is detected at startup and blocked from running during the exam. A friend can't sit in another city and feed answers over a video call.
No parallel browsers
A second Chrome window, an open Safari, a hidden Firefox — they all become an unauthorised Google search waiting to happen. We catch every running browser instance, ask the student to close it, and re-verify before the exam clock starts.
No screen projection
Mirroring the laptop onto a second monitor, a TV or an AirPlay receiver means someone else is reading the questions. We detect any extra display the moment it's connected and pause the exam until it's unplugged.
And the everyday lockdown.
The basics every secure browser should do — done properly.
Full-screen lockdown
The exam takes over the screen — no minimising, no switching out, no chat windows.
Face presence
The webcam quietly confirms the right person is in front of the screen throughout.
Identity check
The first-frame snapshot from the webcam confirms the student matches the registered photo.
Focus tracking
Counts every time the student tries to switch tabs or leave the exam window.
Copy-paste blocked
Clipboard is disabled inside the exam — students must write the answer themselves.
Quick-close blocked
Cmd+Q, Alt+F4, F11 and the close button are all disabled until the test is submitted.
Right-click & dev tools off
Browser inspect, view-source and right-click menus are blocked — no peeking under the hood.
Snapshots & recording
Optional photo and video capture during the session — kept only if the institution turns it on.
Auto-submit on violation
If the institution sets a violation threshold, the exam submits itself the moment it's crossed — no grey area.
One integrity score
Every violation deducts from a single trust score — easy for institutions and recruiters to read.
Tamper-resistant config
The proctoring rules are sealed inside a launch token — students can't edit them from the browser or by inspecting URLs.
VM detection
Spots virtual machines that some students try to use to slip past lockdown by running the exam in a sandbox.
Plug it into your own platform.
Exam Cover Browser isn't tied to FresherBot. Point it at your own server, set your own rules, and launch exams from your own platform. The lockdown configuration is sealed inside a secure launch token so it can't be tampered with from the browser.
- Configurable for any institution or product
- Each exam launch is sealed with a secure token
- One-click launch from your existing platform
- Lockdown rules can't be edited from the browser

How students get going
Download once
Mac or Windows installer — a one-time setup. The download folder includes a short install guide for each platform.
Open the exam link
When a test requires it, the exam link opens directly inside Exam Cover Browser — no extra steps.
Take it securely
Write code, speak, type — graded on the spot, with integrity captured automatically.
First launch may show a standard "unverified developer" warning during the beta — the install guides in the download folder walk through the one-click bypass.
Common questions
How is this different from other secure exam browsers?
Most lockdown browsers only restrict the screen. Exam Cover Browser also grades the work on the spot — code, writing and speech are all evaluated locally on the student's device. That means instant results, far less server load for the institution, and the student's work never leaves their machine.
Do students need to install anything?
Yes — a one-time installer for Mac or Windows. After that, any exam link that needs ExamCover opens straight into it. No browser plugins, no per-exam re-installs.
Is the student's data private?
Yes. Code, writing and speech are processed entirely on the student's device. Only the final results and integrity signals are sent back — raw video, raw audio and intermediate work stay on the laptop.
What stops a student from cheating?
Full-screen lockdown, background app detection, face checks, focus tracking and second-monitor detection all feed a single integrity score that's surfaced to the institution alongside the marks.
What happens if a student loses internet mid-exam?
The grading itself doesn't need internet — code runs, speech is transcribed and writing is scored locally. Once connectivity returns, answers and integrity events are submitted automatically.
Can we use it with our own platform?
Yes. Exam Cover Browser is configurable for any institution or product. Every exam launch is sealed with a secure token that carries the proctoring rules. Write to info@fresherbot.com to discuss integration.
Is it free?
Yes for institutions using FresherBot. For other platforms, integration is offered under a separate arrangement — write to us.
