A general chatbot learned the internet and hopes your exam was in there somewhere. We went the other way: we made the content first, and DhiX AI-1 — our own model — learns from it.
Every question you practise comes from our own bank — 160,000+ of them, authored and reviewed by expert educators, with worked solutions and the real figures from the papers. Not a model's memory of the internet.
160,000+ reviewed questionsDhiX AI-1 is our own exam model, trained on that same content. It reads what you are actually looking at — a printed problem, a diagram, or your own handwritten working — and teaches from what is on the page.
DhiX AI-1 · our own modelAn answer is verified before it appears on your screen. You are never left holding two contradictory explanations at eleven at night, and you never have to be the one who spots the mistake.
on every written answerYour exam, your chapter, your marking scheme — and an All-India Rank read against the exam bodies' own published data. Seven exams today, and the engine is built to take more.
JEE · NEET · CBSE · Foundation · Banking · SSCSaid plainly: the questions are written by people who teach these exams, the model is ours and learns from them, and every correction they make reaches you without you doing anything at all.
Not voice notes. Not a chatbot reading its answer aloud. A spoken call with an AI subject tutor that explains in Hinglish, writes the maths on the board as it speaks, and lets you cut in mid-sentence.

Her board
— nothing yet; she's still talking —
Your microphone is open only while you're on the call, and recordings are never stored.
Interrupt it
Start talking while it's explaining and it stops — instantly. If it was only a cough or the TV, it picks up exactly where it left off, mid-sentence. There is no push-to-talk button to hold.
It writes as it speaks
Every formula it speaks appears on the board at the moment it is said — properly typeset, chemistry included. Conversation writes nothing, exactly like a teacher talking with the chalk down.
Show it the page
Snap the question from your book. It reads it, and a spotlight glides across your own photo to the part being explained — the given data, then the figure, then what's being asked.
Viva mode
Switch to Viva revision and it reverses: it pulls questions from the bank, you answer aloud, and you get a running score and an honest verdict at the end.

The same five steps, every time you ask.
| Open-web AI chatbot | DhiX AI | |
|---|---|---|
| Exam context | Answers in general terms | Knows your exam, chapter and marking scheme |
| Source of truth | The open internet | Our own bank of 160,000+ expert-authored, reviewed questions — and our own model, DhiX AI-1, learning from it |
| Before you see it | Whatever it generated | The answer is checked first — you never get two contradictory ones |
| Notation | Maths and chemistry often break | LaTeX, structures and real figures, as printed |
| Wrong answers | A shrug | Which wrong option you picked, and the mistake behind it once it repeats |
| Your rank | Not modelled | AIR from official cutoff data, tracked over time |
| Parents | Locked out | An honest weekly report from real attempts |
| Teaching style | A text dump | Concept → steps → answer → trap → what to practise |
The exams are Indian and the stakes are Indian. So is everything underneath the answer.
The engine
Not a chatbot with a syllabus bolted on. We author the exam content ourselves, and DhiX AI-1 — our own exam model, which reads a photographed question or a page of your handwriting — is trained on it. Built here, for the exams that decide futures here.
The content
Questions written and reviewed by Indian educators — JEE, NEET, boards, banking, SSC — from an exam portal that has run with real students for years. Never scraped from the open web.
The data
DhiX AI runs on servers in Mumbai. Student accounts, attempts and reports live on Indian soil, under Indian law.
26 seconds. Watch till the end.
Pick yours to create a free account set up for that exam.
Type a doubt, snap a photo, or take the 10-minute adaptive diagnostic.
Ability, chapter mastery, and the exact misconceptions behind your errors.
Practise what moves it. Your AIR and college list update after every session.
An honest weekly report: hours studied, concepts mastered, misconceptions repaired, and the rank trajectory — straight from the engine. No fake progress. If they didn't study, you'll see it.
Question banks, a test series and someone to ask at 11pm are three separate bills — and none of them tells you where you actually stand.
DhiX AI replaces that entire stack for less than a cup of coffee a day.
The whole product under your brand, on your own database: the reviewed bank, the AI voice tutor, mocks on the real exam screen, rank prediction and the parent report. Bring your own content or licence a slice of ours, scoped to the exams you teach. One institute already runs it with real students.
your brand · your database · your students stay yours
Start with the 10-minute diagnostic: it finds the traps you keep falling for, and puts a rank on where you stand today.
Answers come from our own question bank — authored and reviewed by expert educators — not from a model's memory of the internet. Practice, past papers and mocks are served straight from that bank, doubts are taught from it, and an answer is checked before it reaches your screen. We would rather decline than invent.
Seven today: JEE Main, JEE Advanced, NEET-UG, CBSE boards, Foundation (Class VIII–X), Banking (IBPS) and SSC. Doubt-solving isn't boxed into one subject either — ask anything from your syllabus and it answers step by step.
Yes — DhiX AI-1. It is a vision-language model, so it reads a typed doubt, a photographed question, a diagram or your own handwritten working, and it is trained on the same expert-authored Indian exam content the app teaches from. It works JEE- and NEET-level problems step by step, marks them the way the paper does, and improves every time one of our educators corrects something.
Yes. You can ask doubts and get your rank prediction with a college shortlist right now — no account, no card. A subscription unlocks the full engine: unlimited practice, timed mocks, previous-year papers, analytics and the parent report.
A general chatbot is built for everything and specialised in nothing, so it has no way to know when it is wrong about an Indian exam — and neither do you, until results day. DhiX AI runs on DhiX AI-1, our own model, trained on exam content we authored and reviewed ourselves. It checks the answer before you see it, renders real exam formats (equations, figures, passage sets), knows your exact syllabus and marking pattern, and tracks your predicted All-India Rank after every session.
Yes — an honest weekly report: hours studied, concepts mastered, misconceptions repaired and the rank trend. No inflated progress bars. If they didn't study, the report says so.
DhiX AI works both ways. Use it as a complete self-study engine, or alongside your coaching — it clears doubts at 11 pm when no teacher is around, and drills exactly the traps you personally fall for.
Yes. DhiX AI is available white-labelled: the full platform on your own domain, with your branding, on your own database. See the For Business page for details.
