## Positioning

Ottr is a deck-first alternative to Kahoot, Wooclap, Slido, and Mentimeter. Its focus is preserving the presenter's slide flow while adding interaction, feedback, and analytics around the deck.

Ottr is strongest when the presenter already has slides and wants to add polls, gamified quizzes, student Q&A, live whiteboarding, slide mirroring, and analytics without rebuilding the session in another tool.
