Legend is an EdTech company that builds an AI-powered teaching assistant for grading student assignments. Teachers upload student work and the system evaluates it against customisable rubrics, producing personalised, rubric-aligned feedback. The platform supports teacher-created rubrics, student contexts and individual teaching styles, and covers essay and assignment types including argumentative, persuasive, narrative, informational, literary analysis, research papers, DBQs and short response formats. It aligns to academic frameworks such as Common Core, NY Regents, AP, IB and Next Generation standards, and integrates with existing teaching platforms without requiring additional tools.
The underlying technical work spans artificial intelligence, large language models, retrieval-augmented generation (RAG) and natural language processing applied to automated essay scoring. Other areas of focus include educational assessment and rubric alignment, bias-aware AI assessment, and data privacy and compliance. The system reports enabling three times more revision opportunities for students and is designed to deliver grading consistent with manual evaluation. Legend operates in the United States and serves K-12 and higher-education assessment use cases across social studies and writing and language arts.
The company was founded by educators and technologists. Its stated design approach trains the AI on teacher-created rubrics, student contexts and teaching styles rather than producing generic feedback, with the aim of reducing grading workload. Legend reports that it is FERPA compliant and COPPA compliant and adherent to the California Student Privacy Pledge.
