Dropped Out of Columbia to Build the First General-Purpose Learning Agent

Dropped Out of Columbia to Build the First General-Purpose Learning Agent

March 2, 2026

At Columbia, Zhao Yilin and Jiang Ruohan, both newly enrolled, attended a quantum physics hackathon. The lectures spanned from logic gates to code implementation, and the two beginners struggled to keep up. On one side were impenetrable textbooks; on the other, ChatGPT's rapid yet shallow answers. But when they themselves broke down the core concepts layer by layer, they discovered it wasn't as complicated as they'd imagined. In that moment, they realized: knowledge isn't necessarily hard — what's hard is finding someone who can actually explain it clearly.

They weren't satisfied with surface-level answers.

Zhao and Jiang possess what they call "growth outside the structure" — an agency akin to that of an Agent. Not pulled along by predetermined paths, not merely completing assigned tasks, but moving forward with their own judgment. Initially, they studied at Columbia by day and built their company by night. Their meetings had almost no small talk; often the first words were simply: "What problem are you running into?"

In November 2025, Hyperknow, a general-purpose learning agent, was officially launched — built around real learning scenarios with personalized dedicated models, every answer traceable to its source. Three months later, Hyperknow 3.0 went live. It began to think and plan proactively, anticipating your next step.

From last September to now, Hyperknow has completed five major version iterations, with hundreds of minor updates.

Back in high school, Zhao Yilin often wondered: what would it be like to have someone beside him who truly understood his thinking, grasped his progress, and knew his complete background? Later, he gradually became that person himself — someone who could make hard problems simple. Eventually, he realized that what everyone was truly missing was a Hyperknow: a companion that understands your learning context and responds to every question.

Built around real learning scenarios with personalized dedicated models, Hyperknow 3.0 introduces the "All-Round Learning Assistant." It can connect to learning management systems like Canvas, helping users build their own course knowledge bases. The agent proactively captures changes in course progress, judges your likely next actions, and prepares before you even ask.


Hyperknow-Generated Cheatsheet

A cheatsheet is a single page of personal notes permitted in open-book exams. From the perspective of real students, Hyperknow divides the page into four columns, compressing margins and font size while preserving adjustable space. For STEM content, the system proactively extracts all core formulas, annotating the meaning of each symbol and variable.


Hyperknow-Generated Cellular Respiration Concept Explanation

Unlike general models like ChatGPT, which tend to compress source material, Hyperknow can process thousand-page documents and read sentence by sentence, ensuring every piece of information in generated explanations can be traced to its original source page.
