HyperKnow

HyperKnow is a general-purpose learning agent founded by Columbia University dropouts Yilin Zhao and Ruohan Jiang, both born in 2005 . The product launched in November 2025 and has since iterated through five major versions, with HyperKnow 3.0 arriving three months later as an "all-round learning assistant" that connects to course management systems like Canvas LMS, proactively tracks academic progress, and anticipates a user's next steps .

The founders distinguish it from general-purpose models like ChatGPT through learning-scene specificity: HyperKnow handles thousand-page documents with sentence-level source tracing to specific page numbers, generates formatted cheatsheets and flashcards, and employs an "agent thinking" mode that searches across dozens of web pages with paragraph-level attribution . Pricing is set below ChatGPT, with a fully free tier aimed at student affordability . The team, largely recruited from early users, operates on what the founders call "structural growth force" — the capacity to rebuild the entire product within a week and measure breakthroughs in half-week increments .
