Turn Your Content Into an AI Tutor That Teaches Like You.
Upload your video lectures, YouTube playlists, and PDF notes. Your students get a chatbot that answers every doubt from your material, in your teaching style — with exact video timestamps and page references.
From Your Content to a Working Bot in Four Steps
No re-recording, no restructuring, no technical setup. If you have the content, you're one upload away from a bot.
Upload Your Content
Drop in your recorded lectures, paste YouTube links, and upload PDF notes. Anything you already teach with — no re-recording, no reformatting.
AI Builds Your Knowledge Base
The AI transcribes every video, reads every PDF, and indexes it all — down to the minute of a lecture and the page of a document.
Your Bot Learns Your Style
The bot picks up how you explain — your analogies, your shortcuts, your language. It answers the way you would in class, not like a generic chatbot.
Students Chat, Anytime
Students ask doubts 24/7 and get answers backed by your content — with the exact video timestamp and page reference to go deeper.
One Bot. Every Surface You Own.
Your bot isn't locked inside PrepLab. Drop it on your website, ship it in your app, share it as a link — or build something entirely custom with developer APIs.
Your Website
Copy-paste snippetPaste one small script tag and a chat widget appears on your institute's website — branded as yours, answering from your content.
Your Branded App
Built inThe bot lives inside your white-label student app out of the box — no extra setup, right next to tests and lectures.
A Simple Share Link
Link & QREvery bot gets its own link and QR code. Drop it in your WhatsApp group, print it on notes, or pin it in your Telegram channel.
Developer APIs
REST APIClean REST APIs give you the raw answers — with timestamps and references in the response — so your team can build any experience on top.

POST /api/v1/bots/{bot_id}/chat { "message": "Why limit h → 0?" } // response { "answer": "Remember the zooming-in idea from class…", "sources": [ { "type": "video", "title": "Differentiation L-3", "timestamp": "12:45" }, { "type": "pdf", "title": "Calculus Notes.pdf", "page": 18 } ] }
Every Answer Comes With Receipts
Generic AI chatbots make things up. Your StudyBot cites its sources — the lecture, the minute, the PDF, the page — for every single answer.
The rate of a reaction doubles for every 10°C rise because the fraction of molecules crossing the activation energy barrier grows exponentially — remember the Maxwell curve we shaded in class.
One tap on a citation takes the student to the exact moment of your video or the exact page of your notes. Doubt solving becomes revision.
Not Another Chatbot. A Second You.
Your bot doesn't replace your teaching — it multiplies it. Every lecture you've ever recorded keeps answering doubts long after class ends.
Answers Only From Your Content
The bot is grounded in your knowledge base — not random internet answers. If it's not in your material, the bot says so instead of making something up.
Video Timestamps, Not Vague Links
Every answer that comes from a lecture links to the exact moment — "Watch from 12:45" — so students revise the 2 minutes that matter, not the whole hour.
Page-Level PDF References
Answers from notes and books cite the document and page number. Students learn to trust the material — and open it more often.
Your Teaching Style, Preserved
Trained on how you explain concepts, the bot mirrors your approach. Students feel like they're asking you — because in a way, they are.
Doubts Solved at 11 PM
Most doubts come during late-night self-study — exactly when you're unavailable. Your bot handles them instantly, so momentum never breaks.
See What Students Struggle With
A dashboard of every question asked shows which topics confuse your batch — so your next class targets exactly what they need.
A Day in the Life of Your Bot
While you teach, sleep, or take a Sunday off — your bot keeps working.
Late-night self-study
A student stuck on electrostatics asks the bot instead of waiting until tomorrow. They get your explanation, plus the exact 3 minutes of Lecture 9 to rewatch — and keep studying.
Pre-exam revision
Before a mock test, a student fires 14 rapid questions at the bot. Every answer links back to your short notes — page by page — turning panic into targeted revision.
Your dashboard
You open the questions dashboard: 60% of the weekend's doubts were about integration by parts. Your next class starts exactly there. No guessing.
