CrowdHum lets presenters create live audience polls and read their results from chat. Create a poll in a new room, add more polls to an existing room code (one QR, many polls), fetch live or final vote tallies, list your sessions and polls, read an AI session recap, and invite a co-owner. Visualization modes include column drift, rising bubbles, word cloud, 2x2 grid, ranking, and Q&A. The live presenter show (reveal, pause, vote streaming) stays in the CrowdHum web app.
