Product · Examness
Examness is a learning platform for developers and IT professionals. It puts four things in one place that usually live on four separate sites — and it keeps your wrong answers on purpose, because they are the most useful thing you produce.
What is inside
Everything a person does in one part is visible to the others. Practice feeds the teacher; the teacher knows what the Code Lab could not run.
Thousands of exam-style questions with written explanations, timed mock exams at full length, and per-domain score tracking for AWS, Azure and other certifications. Results break down by domain, so a weak area is named rather than guessed at.
More than 3,200 curated questions and answers across over thirty topics — Python, JavaScript, React, SQL, machine learning, NLP, SAP and more — split into beginner, intermediate and advanced. Many answers carry a diagram drawn from that answer's own content.
Python and JavaScript exercises across three levels, each with a brief, staged hints, real tests and a reference solution. The code runs inside your own browser, which is why running and testing it is free and why an infinite loop can always be stopped.
Tutors that are shown your recent wrong answers, your weak exam domains and the exercises you have run repeatedly without passing — before they reply. The lesson starts at the gap instead of at chapter one.
The idea underneath
Most practice tools treat a wrong answer as something to erase and move past. Examness treats it as the input. Every answer a signed-in person gives is stored, including — especially — the ones that were wrong, and the interface says so plainly at the point of answering rather than in a privacy policy.
That record is what the AI teacher reads. Before it writes a single line of reply it has been shown what you picked, what was correct, which domains are costing you marks, and which coding exercises you have failed more than once. A generic tutor starts from a syllabus. This one starts from your actual gaps.
Questions can be reopened and answered again. A revision is counted rather than overwritten, because a question somebody has changed their mind about three times signals uncertainty, not carelessness — and that is worth knowing.
In the Code Lab
Reading a finished solution teaches very little. Finishing a half-written one teaches a great deal, so the Code Lab is built around interrupting the machine rather than waiting for it.
Press Let AI write it and a solution streams into the editor line by line. Press Stop at any moment and generation halts for real — the text is not merely hidden — leaving whatever has been written in the editor, yours to complete. The dashboard counts how many exercises were solved this way, because that number is the one worth improving.
Tests show pass or fail with what your code returned against what was wanted. After two or more failed runs on the same exercise, and only then, a card offers to hand the problem to your AI teacher, who can already see the attempts and the failing test. One failed run is usually a typo, and the hints cover it.
Pricing
Reading, practising and running code cost nothing to serve, so they cost nothing to use. Credits buy model time and only model time. Every new account gets fifty of them, once.
Running out of credits stops none of it. Only the AI buttons wait for a top-up.
| AI action | Credits |
|---|---|
| AI writes a code solution for you | 1 |
| AI reviews your code | 1 |
| AI explains code | 1 |
| Explain an exam answer | 1 |
| Weakness summary | 1 |
| Generate a study plan | 2 |
| Message to an AI teacher | 2 |
One credit is ₹0.50, or about $0.01. Every AI button shows its price beside it, the header carries the balance at all times, and a request that fails is refunded automatically — nobody is charged for an answer that did not arrive.
Also in the product
A day-by-day plan generated from the domains that are actually costing you marks, and a readiness view that estimates how close you are to passing from your attempt history.
Each question carries a thread. Candidates post their reasoning under a username of their choosing, comments can be upvoted, and the best explanation often lives there rather than in the official answer.
Three arcade-style rounds that quiz you on AWS and Azure services, with sound, scores and leaderboards. Questions rotate so the same ones do not come round again. Games never cost credits.
Exam attempts and domain scores, practice history marked answered, correct and to review, Code Lab progress, and game standings — each panel linking onward to the thing it summarises.
English, Hindi, Bengali, Japanese and Indonesian, switchable from any page, with light, dark and a system setting that follows the device.
The mobile app signs into the same account and shares the same balance, history and progress. Code executes on the web, where the browser is the sandbox, and the app says so plainly rather than pretending otherwise.
Every practice question, interview answer and coding exercise can be read without an account. An account adds memory, and fifty credits.
