Two scholars developed a chatbot aimed at helping students disagree productively, and early classroom pilots have drawn praise from faculty who say it scaffolds civil debate. The tool prompts evidence‑based responses, reframes arguments and coaches students on rhetorical moves, with instructors reporting improved discussion quality in some courses. Adopters note the tool is not a substitute for pedagogy and raise questions about assessment, academic integrity and equity of access. Developers and faculty who have trialed the chatbot emphasize the need for clear use policies and instructor oversight to ensure AI scaffolding strengthens, rather than short‑circuits, student reasoning.
