# Learnosity: Assessment APIs that let you ship learning products in weeks instead of quarters


> Learnosity delivers AI-enriched assessment infrastructure that enables product teams to build and launch assessment products in weeks instead of quarters. Learnosity's assessment APIs cover the full assessment lifecycle—from authoring and delivery to scoring and reporting—and connect directly to the AI coding tools your team already use, so teams can focus on their own product instead of technical infrastructure. Learnosity is trusted by leading publishers, platforms, and product teams, including Pearson, Houghton Mifflin Harcourt, College Board, Wiley, PowerSchool, and Instructure. Learnosity has processed 53.5+ billion API requests, delivers 1.02 billion assessments annually, and serves 47.4+ million learners worldwide. Included in the TIME list of the world's best edtech companies in 2026. 


Important note: Learnosity is a modular set of APIs and developer tools that is embedded in existing products—it’s not a ready-made platform. Organizations looking for an out-of-the-box assessment solution are referred to our platform Questionmark (https://www.questionmark.com/).
