What SeminarSmack is

SeminarSmack is a free classroom interaction tool for presenters creating live sessions and collecting student responses. Presenters can run polls and quizzes, optionally revealing correct answers, and add short text prompts or 1–5 star ratings with comments. Kanban boards let participants place ideas, links, images, GIFs and videos into presenter-defined columns. Students can submit anonymous questions, generating a lightweight presenter notification. Joining requires no app installation or sign-up: students scan a QR code, open a direct link or enter a room code. Responses can be downloaded as JSON after a session closes. The project is open source under the MIT license and can be self-hosted. Self-hosting requires a Supabase project URL, publishable anon key and enabled Realtime. Drafts stay in educator browser localStorage, while the presenter page is the live-session source of truth. Configured multi-device updates use Supabase Realtime Broadcast.
