Piazza is a social Q&A platform designed for academic courses. Students post questions (by name or anonymously), collaborate to build wiki-style answers, and receive follow-up responses from instructors and TAs. Faculty use Piazza as a central, searchable hub for all course questions — reducing repetitive email and increasing student participation outside of class.
Piazza supports a wiki-style answer format where multiple students can contribute to a single response and instructors can endorse the final answer. The platform supports LaTeX, syntax-highlighted code blocks, images, and file attachments — making it well-suited for STEM, CS, and quantitative courses.
