Hey, I'm Saurav Thakur.
For the last 5 years, I've been obsessed with AI. Not casually watching YouTube tutorials, but actually investing lakhs of rupees in paid university courses, certifications, and premium tools. I've mastered Machine Learning, Deep Learning, NLP, Computer Vision, LangChain, prompt engineering, full-stack development, cloud deployment (AWS, Firebase), and AI automation - the complete tech stack that companies pay ₹10-20 LPA for.
I've built 48+ production-grade AI applications (32 websites + 14 mobile apps + 1 custom browser) that 5,000+ real people use every day - applications that have improved productivity and decision-making across finance, legal, travel, insurance, healthcare, education, and social networking domains.
Currently pursuing B.Sc. Dual Specialization in Physics (Hons.) & Computer Science from SS Jain Subodh PG College, I've been working as an AI Systems Architect & Full-Stack Developer since August 2024, delivering end-to-end production solutions for clients worldwide.

This knowledge shouldn't be locked behind expensive courses or elite college degrees. So here's my promise to every Nexbook team member:
Because I believe the future belongs to those who understand AI. I'm still a student, just like many of you. But I've spent countless nights learning, building, failing, and succeeding. I want to build a team of people who don't just USE AI - but truly UNDERSTAND it, BUILD with it, and CREATE the future with it.
This isn't a typical internship where you make PPTs or do data entry. This is your shortcut to becoming an AI expert. The same journey that took me 5 years and built 48+ applications serving 5,000+ users? You'll get it in 6-12 months with hands-on guidance. No gatekeeping. No holding back. Complete knowledge transfer.

Welcome to NexBooK - A Gift from Seniors to Every Student
Think about this: It's 2 AM, exam tomorrow, and you desperately need that one textbook, Notes or PYQs. Or it's the beginning of semester, and you're calculating if you can afford both the Winter Blazer, lab coat AND the reference books. We've been there. Every single one of us.
That's why we, a group of final-year students from S.S. Jain Subodh College, built NexBooK - not as a project, not for marks, but as our legacy. A gift to every junior who walks the same corridors we did, faces the same struggles we faced, and dreams the same dreams we dreamed.
Remember when seniors used to pass down their books and notes? That beautiful tradition of helping each other? We've digitized that spirit. NexBooK isn't just another website - it's that helpful senior you always wished you had, available 24/7 in your pocket.
We spent our final year not just studying, but building something that would outlive our time in college. Every late-night coding session, every feedback form, every feature - everything was designed with one question in mind: "Will this actually help a student like us?"
We didn't create just a marketplace. We built a complete student ecosystem:
Everything you need for your entire academic journey, all in one place:
A community initiative to share knowledge freely. More than just buying and selling - it's about building a culture of sharing:
Think about it: Your old engineering textbook could be someone's ticket to acing their semester. Their literature collection could be your gateway to new worlds. We've made it simple, safe, and completely free.
Imagine an app where WhatsApp's instant messaging, Instagram's stories, Posts, Facebook's events, LinkedIn's professional networking, and Twitter's real-time updates come together - but only for verified students. No noise. No fake IDs. No spam. Just real campus connections.
Why NEX is Revolutionary:
NEX isn't just about likes and chats. It's a complete ecosystem where your social life, professional growth, and academic collaboration merge seamlessly:
NEX Features:
This is social media, reimagined for students. This is your campus, digitized.
A fusion of ChatGPT-5 Thinking and NEX-3 technology. This isn't just another chatbot - it's your 24/7 personal assistant for everything:
Whether you're writing an assignment at 3 AM, creating a presentation, or need help understanding a concept - NEX AI is there, always free, always unlimited.
Your intelligent study partner powered by advanced AI technology:
Upload any notes, any syllabus - Thinkly transforms it into your personal study guide. Study smarter, not just harder.
Yes, you read that right. Over 250,000 courses with certificates from Google, MIT, Harvard, Stanford, and hundreds of other prestigious institutions. All accessible. All free.
Want to learn Machine Learning? Done. Digital Marketing? Available. Web Development? Right here. Every course comes with a certificate to boost your resume while you're still in college.
A trust-first marketplace where students help students:
Every book you buy saves you money. Every book you sell helps a fellow student. It's a cycle of support.
Your entire academic life, organized and accessible 24/7:
No more hunting through WhatsApp groups or notice boards. Everything you need is right here.
Every contribution counts, every action matters:
Climb the leaderboard, build your campus reputation, become the senior everyone looks up to. Be the senior you wished you had.
This is more than a platform. It's a movement. A promise from every senior to every junior: "We've got your back."
"The beautiful thing about learning is that nobody can take it away from you."
- Team NexBooK

Saurav Thakur & Team NexBooK
