Rohan Gupta’s entrepreneurial journey began in Chicago, where he studied computer science and saw students struggling with writing assignments. Instead of ignoring the problem, he imagined a future where AI could help people write smarter and faster. Alongside his co-founders, Rohan began experimenting with early NLP models—long before AI tools became mainstream. This bold curiosity set the stage for QuillBot, one of the world’s most widely used writing platforms.
Building QuillBot: Solving a Real Problem with Smart Technology
In 2017, Rohan co-founded QuillBot, an AI-powered writing assistant built to help users paraphrase, summarize, and write more effectively. The idea was simple yet revolutionary make writing easier for everyone, not just experts. QuillBot’s user-friendly design and powerful rewriting engine quickly went viral among students, content creators, and professionals. What started as a small college project soon grew into a platform used by millions across 150+ countries.
Facing Challenges While Scaling a Global AI Tool
Scaling QuillBot wasn’t easy. Competing against giants in the writing-tech industry and continuously improving AI models required deep R&D, disciplined execution, and constant innovation. Rohan’s leadership ensured that QuillBot remained ahead with features like grammar correction, summarization, and citation generation. In 2021, QuillBot was acquired by Course Hero, marking one of the most successful exits by a young AI founder proving that solving real problems beats chasing trends.
Becoming a Global Leader in AI-Assisted Learning
Today, Rohan Gupta stands as a powerful inspiration for young AI entrepreneurs. His work with QuillBot has transformed how millions write, learn, and communicate. Beyond being a tech founder, Rohan has become a global advocate for ethical AI, emphasizing tools that enhance learning rather than replace it. His journey shows that a clear vision, relentless curiosity, and a problem-first mindset can lead to world-changing innovation.
