Georgia Tech Jill Watson: First AI Teaching Assistant, Outperforms ChatGPT in Classrooms

Georgia Tech’s Jill Watson, first deployed in 2016 using IBM’s Watson platform, became the first AI-powered teaching assistant used in real classes — initially answering student questions on discussion forums like Piazza using course syllabi and a curated knowledge base of past Q&As. A 2025 evaluation shows the latest ChatGPT-powered version outperforms OpenAI’s own assistant in real online classrooms and correlates with better academic outcomes. The Georgia Tech Research News report covers a September 2025 evaluation of the latest Jill Watson version, built on ChatGPT by the Design Intelligence Laboratory (DILab) and the U.S. National Science Foundation AI Institute for Adult Learning and Online Education (AI-ALOE). Researchers believe this is the first documented instance of a chatbot enhancing teaching presence in online learning for adult students. Jill Watson evolved through three distinct technology generations: the 2016 IBM-Watson version used curated Q&A knowledge bases; the 2019 Google BERT version worked across learning management systems like EdStem and Canvas with broader generalization; the 2024-25 ChatGPT version uses generative dialogue grounded in courseware, textbooks, and video transcripts. The latest version was widely covered by The Chronicle of Higher Education, The Wall Street Journal, and The New York Times when it first launched. Technically, Jill Watson is built around the Community of Inquiry (CoI) framework and is designed to enhance teaching presence — one of three key factors in effective online learning alongside cognitive and social presence. The architecture includes a pipeline that ingests course materials, builds a retrieval-augmented context for each student question, and routes responses through ChatGPT with safety guardrails tuned for the academic context. Jill Watson has been deployed across multiple Georgia Tech online courses and serves thousands of students per semester. Future direction, per the DILab team, includes expanding Jill Watson to other universities through the AI-ALOE institute, adding multilingual support, and deepening the model’s ability to give feedback on student writing rather than just answering questions. The team is also exploring how the same architecture can support community college and adult-learner populations beyond Georgia Tech.
