Study24by7 combines curriculum-grounded AI tutoring, voice, vision, assessments and offline intelligence into one learning ecosystem built for schools.
A complete AI learning ecosystem for Classes 6–12 — NCERT, CBSE, ICSE and other boards.
Class 8 · Science
Heat Transfer
ReadingHow heat travels
When one end of a metal spoon is kept in hot tea, the other end soon feels warm. Heat travels along the spoon by conduction — it passes from the hotter end to the cooler end through the solid itself. Metals are good conductors; wood and plastic are poor conductors, which is why pan handles are made from them.
Student asked: “Explain conduction simply”
Vidya replied: Conduction is how heat moves through a solid, particle by particle…
Demonstration data
One AI ecosystem
Students, teachers and the school share one intelligence layer — so a question asked in class, a homework upload and a principal's dashboard all draw on the same understanding of every learner.
Study24by7 Intelligence Layer
Powered by Vidya
One shared understanding of every learner, every chapter and every class. Each part of the school reads from it and writes back to it, so nothing a student does is lost between the classroom, the staff room and the office.
Learn
Everything a student touches — the textbook, the tutor, practice and exams — runs on the same intelligence layer. Ask a question out loud and get an explanation grounded in the chapter you are studying. Revision adapts to what you actually know, not to a fixed schedule.
Intelligence flows out to students, teachers and the school
The product
The same lesson, the same class, the same data — shown differently to the people who use it. Students see what to study next, teachers see who needs help, and school leaders see how learning is going across every class.

For students
A plan for today, not a syllabus for the year
Every morning the plan picks the chapters and revisions that matter most right now, based on mastery and what the class is covering.
Ask Vidya from anywhere
Type or speak a doubt and get an explanation grounded in the exact chapter being studied — not a generic answer from the web.
Revision that comes back at the right time
Flashcards resurface just before they would be forgotten, so a streak of short sessions does the work of long cramming.
Vidya SLMs
Study24by7 runs on Vidya — small language models purpose-built for the classroom: they know the syllabus, the grade, and what a good explanation looks like, and every answer is grounded in the chapter the student is studying.
Vidya
Six education-specific models, one shared understanding of the curriculum
General education tutor, chat and content generation
Maths, reasoning and step-by-step solving
Speech, transcription and voice commands
Diagrams, handwriting, worksheets and OCR
Deep reasoning, long-context study and research
Kiosks, IoT devices, FAQ and command routing
Inside a single answer
Vidya never answers from memory alone. Each question is placed in its grade and chapter, matched to the relevant passages, reasoned over, checked, and only then explained.
Worked example
Stage 1 of 6
Student question· Input
“Why does ice float on water?”
Explanations are built from the chapter the student is studying, so what Vidya says matches what the exam expects.
The same question gets a different answer in Class 6 and Class 11 — the vocabulary, depth and examples follow the syllabus.
Models sized for education respond quickly and can run inside the school on edge hardware, so learning continues when the internet drops.
Voice AI
Ask a question in your own words and hear a patient teacher answer — grounded in the chapter you're studying. VIDYA-Audio handles the listening and the speaking, so there is no typing and no reading barrier.

Waiting for a question
Demonstration data
Voice models tuned for the way students across India actually speak.
Interrupt, ask "why?", or say "explain that again" — like talking to a teacher.
Recognises the terms, names and units from the textbook, not just everyday speech.
Built to add more languages as they are ready for the classroom.
Works with the AI Smart Speaker, so a question never needs a screen.
How it works
Every answer is grounded in the chapter the student is studying, so a spoken reply stays on the syllabus.
Vision AI
Snap a photo of handwritten work, a diagram or a textbook figure. Vidya reads it and walks the student through it, step by step.
Scan your work
Demonstration data
Notebook page with the handwritten problem “2x + 5 = 17, find x” and a hand-drawn right-angled triangle with sides labelled 3 cm and 4 cm.
Demonstration data — a sample linear equation, not a real student’s work.
Homework stays in the notebook. No retyping, no special worksheets — just pen and paper the way class already works.
One tap on a tablet or phone. The page is framed, straightened and cleaned up automatically, even under classroom lighting.
VIDYA-Vision, Vidya's vision model, separates the working from the diagram, read the handwriting and understand what the question is asking.
Instead of a final answer, the student gets the next step — grounded in the chapter, at the level of their class.
Reads worked solutions across maths, science and language — including crossed-out attempts and margin notes.
Understands the diagrams students meet in their books — geometry, circuits, cell structures, maps and graphs.
Offline AI
Schools lose connectivity; learning shouldn't. Study24by7 can run Vidya on an edge device inside the school, so students keep learning and data stays on campus.
Internet at the school
Try it — switch the school offline.
A cloud connection at the top links to a school edge device in the middle. The edge device serves five classroom devices along the bottom. When the internet drops, the cloud link breaks, but the edge device keeps serving every classroom device.
Cloud
Connected
School Edge Device
Local AI · ready
Online. Classrooms are served locally while the edge device stays in sync with the cloud.
Students keep asking Vidya questions, reading and practising through an outage. Lessons don't pause because the line does.
When the edge device serves a classroom, questions, answers and student work stay inside the school. Nothing has to leave the building to get an explanation.
With an edge device deployed, Vidya SLMs run on hardware inside the school — so response times don't depend on the connection outside the gate.
How it is wired
School Edge Device
Installed on campus, on the school network.
Local AI
Vidya models running on the edge device.
Classroom devices
Tablets and AI speakers, served over the local network.
The Offline AI Tablet and Intel EdgeAI hardware are part of the same ecosystem — one platform from the edge server to the student's desk. Explore devices
The hardware ecosystem
Many classrooms don’t have reliable internet, a shared screen or a device for every child. So Study24by7 ships Vidya on hardware built for those rooms: a speaker you talk to, a tablet that works without a network, and an edge server that brings the intelligence onto the campus.
Microphone array. Picks up a question from anywhere in the room, over the usual classroom noise.
A screen-free way to put Vidya in the room. A student asks a question out loud; the speaker answers in clear, natural speech, grounded in the chapter the class is studying.
Microphone array
Picks up a question from anywhere in the room, over the usual classroom noise.
Speaker
Clear, room-filling speech so the whole class hears the same explanation at the same time.
Voice AI
VIDYA-Audio is tuned for Indian accents and classroom vocabulary, so “photosynthesis” and “Pythagoras” are understood the first time.
Classroom mode
The teacher sets the class, subject and chapter, so answers stay on the day’s topic and at the right level for the room.
A science lesson pauses on a question: why does ice float on water? Instead of waiting for the next period, a student asks the speaker. Vidya explains it in a few sentences at the right level for the class, and the teacher builds on the answer. No devices to hand out, no logins, no interruption.
Full specifications available on request.
Digital textbooks. Board-aligned chapters with read-aloud, highlights and notes, stored on the device.
Digital textbooks, the Vidya tutor, practice and assessments — all installed on the tablet itself, so learning doesn’t depend on the network.
Digital textbooks
Board-aligned chapters with read-aloud, highlights and notes, stored on the device.
AI tutor
VIDYA-Core and VIDYA-Think run on the tablet, so a student can ask a question and get a chapter-grounded explanation without a connection.
Practice & revision
Adaptive questions, flashcards and chapter quizzes that pick up exactly where the student left off.
Works without internet
Everything above runs offline. Progress syncs to the school and to teachers’ dashboards whenever a connection appears.
A student opens the tablet on the bus home. The signal drops halfway, but the chapter, the tutor and the revision plan keep working. By the time she reaches school the next morning, her progress is already on her teacher’s dashboard.
Full specifications available on request.
On-campus inference. The Vidya model family — Core, Think, Audio and Vision — runs on the server inside the school, not in a distant data centre.
An on-campus server that runs Vidya for every classroom at once. Speakers, tablets and school computers connect to it over the local network — the internet becomes optional.
On-campus inference
The Vidya model family — Core, Think, Audio and Vision — runs on the server inside the school, not in a distant data centre.
Serves many devices
One server answers questions from classrooms across the campus, sharing textbooks, practice banks and tutor sessions over the school’s own network.
Data stays local
Student questions, work and progress are processed and stored on campus by default, under the school’s control.
Offline-first
Built to keep working through outages. When the connection returns, updates and analytics sync in the background.
School connects to the edge server, which serves 30, 50, 100 devices depending on the deployment.
The school’s connection goes down at nine in the morning. Nobody notices. Tablets in one class keep opening chapters, the speaker in another keeps answering questions, and the afternoon assessment runs on schedule — all served from the edge server in the staff room.
Full specifications available on request.
We’ll walk through which devices fit your classrooms and your connectivity.
How learning happens
One connected loop, not seven separate apps. What a student reads shapes what they ask, what they ask shapes what they practise, and every result feeds back into what comes next.
Step 1: Learn
Open the chapter as a digital textbook, with read-aloud narration and notes in the margin.
Step 2: Ask
Ask a question out loud or type it. Vidya answers from the chapter you are studying, at your grade level.
Step 3: Understand
Get a step-by-step explanation, a worked example or a diagram walk-through until the idea clicks.
Step 4: Practise
Practice questions get harder as you improve and ease off where you are struggling.
Step 5: Revise
Flashcards built from your weak spots come back at the right moment, with a daily plan that keeps revision short.
Step 6: Test
Chapter tests, mock papers and teacher-set exams — online or on paper, with evaluation built in.
Step 7: Improve
See exactly which concepts to work on next, and teachers see the same picture for the whole class.
Every step is grounded in the same chapter, so the tutor, the practice set and the test paper always agree on what a student is meant to know.
Teacher intelligence
Study24by7 takes the repetitive parts of a teacher's week — setting questions, marking, chasing homework, spotting who is falling behind — and hands back the time. Vidya assists; the teacher decides.
Pick a chapter and a difficulty. Vidya drafts questions grounded in that chapter, and you edit or approve before anyone sees them.
Send reading, practice or a quiz to a whole section in one step, with a due date. Reminders go out without you chasing.
Photograph an answer sheet. Vidya reads the handwriting, checks it against the marking scheme and suggests marks you can accept or change.
Mastery is tracked by topic, not just by test. When a class stalls on a concept, you know that week — not at the report card.

Whole school, all classes
Study24by7 gives a school one place to see how learning is actually going — and the tools to act on it the same week.
Security & privacy
A school is trusting us with its students. So access is decided by the school, sessions do not linger, data travels encrypted, and the AI stays inside the curriculum — with the option to keep processing on campus entirely.
Tablet, speaker or browser. Every session starts with a school-issued sign-in.
Requests leave campus encrypted over HTTPS — or never leave it at all.
With an on-campus edge server, questions are answered inside the school network.
Role-based access and expiring sessions decide who can see what.
Vidya answers from the curriculum, behind a safety and relevance layer.
What is in place today
Each role sees only what it needs — students their own work, teachers their classes, administrators the school.
Sessions expire automatically, so a shared classroom device does not stay signed in.
Data moving between a device and Study24by7 is encrypted using HTTPS.
Vidya answers from the chapter being studied, with a safety and relevance layer designed for school-age learners.
Schools that prefer it can run Vidya on an edge server inside their own network.
Students and teachers receive accounts from their school. There is no open registration.
We distinguish between designed to support, ready, compliant and certified — and we only claim what we can show. Security and privacy documentation is available to schools on request.
The four words we use
Ask for our security and privacy documentation during the demo.
Accessibility
Accessibility is a product feature, not a setting buried in a menu. Every option below is the same one students, teachers and parents use inside Study24by7 — and each one works on this page too.
Scale every page up to 160% without breaking the layout — textbooks, quizzes and the tutor included.
Switch the whole product to OpenDyslexic, a typeface with weighted letterforms that reduce flipping and crowding.
Deepen text and interface colours for low vision or bright classrooms, without a separate “accessible” version.
Turn transitions into simple fades. Switched on automatically when the device asks for it.
Always underline links so they never rely on colour alone.
Narrow the reading column so long chapters are easier to track line by line.
Settings apply instantly and are remembered on this device, so a student sets them once and every page — textbook, practice, tutor — follows.
Curriculum & language
Study24by7 covers Classes 6–12 across NCERT, CBSE, ICSE and other boards, with a curriculum-agnostic content pipeline that adapts to your board, medium and academic calendar.
Boards
Classes 6 to 12
Learning in English and Hindi, with Urdu content and a right-to-left-ready interface for more languages.
The interface is built to mirror for right-to-left scripts, so adding a language does not mean redesigning the product.
Questions
The questions school leaders, teachers and parents ask us most. If yours is not here, bring it to the demo — we would rather answer it than guess.
