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, running on GPU servers we operate — 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 and running on GPU servers we operate. 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 model · our own serversEvery written answer is checked by an independent second model before it is shown, and on a voice call the checker follows the tutor and speaks a correction if one is needed. You are never left holding two contradictory explanations at eleven at night, and you never have to be the one who spots the mistake.
checked by a second modelYour exam, your chapter, your marking scheme — and an All-India Rank estimate read against historical cut-offs and this year's submitted marks. Seven national exams and the first state CETs today, and the engine is built to take more.
JEE · NEET · CBSE · Foundation · Banking · SSC · State CETsSaid 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; recordings are not stored — only the transcript stays in your chat history.
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.
Five AI tutors, one number
Ask Shruti a chemistry doubt and it will say so, and hand you to Neha. Priya takes anything. Five named AI voices, each one consistent every time you call.

We map your practice ability against historical cut-offs and the live blend of this year's submitted marks for your exam and category; official JoSAA & MCC closing ranks (5 years) drive the college shortlist — IITs, NITs, AIIMS, GMCs — re-sorted every time your rank moves. It's an estimate: real ranks depend on the final candidate pool and normalisation. The card alongside is doing it for two sample cases: a JEE Advanced AIR 9,000 and a NEET AIR 5,600.
You've seen how an answer is checked. Everything below runs on the same content and the same rank engine.
A sparring partner calibrated to your exact level races you through drills — practice sticks when there's someone to beat.
Full-length mock tests in your exam's exact pattern and timing — with section-wise analysis and your predicted rank updated the moment you submit.
Practice the entire syllabus, plus indexed previous-year papers (2013–2026; the newest papers are still being indexed) — every question expert-authored and checked, never scraped or invented.

| 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 | Every written answer is checked by an independent second model before it is shown; on a voice call the checker follows the tutor and speaks a correction if one is needed |
| 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 | An AIR estimate from historical cut-offs and this year's submitted marks, tracked over time |
| Parents | Locked out | An honest weekly report from real attempts |
| Teaching style | A text dump | Concept → steps → boxed answer, the trap named, then what to ask next |
None of this got a launch post. It has simply been there. For JEE Advanced alone the bank holds 38,984 questions across 105 chapters — 1,000 on Rotational Dynamics by itself.
Languages
Interface in English, हिन्दी, తెలుగు and தமிழ்; the tutor answers in English, Hindi and Hinglish, and the voice tutor speaks English, Hindi, Telugu and Tamil.
State CETs
Both in the exam picker; EAPCET in the rank predictor, with two EAPCET papers in the previous-year library. Medical CETs are still on the roadmap.
Study plan
Week-by-week chapter targets built around your exam date — and a “Rebuild it” reset when life gets in the way.
Revision
A “due for review” queue, ordered by your mastery of each chapter, so what you nearly know comes back before you forget it.
Weightage
How much each chapter is worth is counted from our own previous-year paper bank, not copied from a coaching pamphlet.
The twin
Your Digital Twin is the rank trajectory that moves with every attempt; the Misconception Genome is the concept-health map that names the trap behind each repeated mistake.
The exams are Indian and the stakes are Indian. So are the content, the model and the place your records are kept.
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 and runs on GPU servers we operate. 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
Your account, attempts and reports live on Indian soil, under Indian law. The model runs on GPU servers we operate; prompts carry no name, phone or email.
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 estimate and college list move as your practice does.
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.
5 questions a day without an account; a free account gives 30 a day. Free during launch — every feature open to signed-in students. See the plans →
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 — Lyceuma, a separate company — 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 — 5 questions a day without an account; a free account gives 30 doubts a day, 20 messages and 20 practice questions per 2-hour session, and 15 minutes of voice tutor a day. Every feature is free during launch. Paid plans are not open yet.
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.
