About Squirrel AI
Squirrel AI Learning was founded in 2014 in Shanghai, China, by Derek Li to develop adaptive learning technology for K-12 education. The company builds AI-powered tutoring systems designed to personalize instruction by breaking subjects into granular knowledge points and adjusting content delivery based on individual student performance.
The company's core product is used in learning centers across China, combining in-person tutoring centers with software that diagnoses knowledge gaps and generates customized learning paths in subjects such as math, English, and Chinese. Squirrel AI has positioned itself as a competitor to human tutoring by arguing its adaptive engine can identify specific misconceptions more precisely than a classroom teacher. The company has also pursued research partnerships and published work related to its learning algorithms and knowledge graph technology.
Squirrel AI has raised funding from investors including Lightspeed China Partners, IDG Capital, and Tencent-affiliated funds across multiple rounds. The company scaled to thousands of learning centers in China during its growth period in the late 2010s, though it faced headwinds after China's 2021 regulatory crackdown on for-profit tutoring in core academic subjects, which affected its domestic business model and prompted exploration of international markets.

Competitive Landscape
Who Squirrel AI competes with, and how they differ.
Khan Academy is a US nonprofit offering free K-12 practice content and an AI tutor (Khanmigo), while Squirrel AI runs paid, largely China-based physical learning centers built on a proprietary adaptive diagnostic engine and licensed courseware.
1 product reviewed on TopReviewedALEKS, owned by McGraw Hill, is a US K-12/higher-ed adaptive math assessment and practice engine sold directly to schools and individual learners online, versus Squirrel AI's broader subject coverage (math, English, Chinese, physics, chemistry) delivered through owned/franchised in-person centers and smart tablets.
DreamBox Learning, now part of Discovery Education, sells adaptive K-8 math and reading software directly into US school-district classrooms, while Squirrel AI's US arm licenses its China-built engine to run its own franchised after-school learning centers rather than selling into schools.
