Pitch Deck · 2026 — 1 / 9

Amphi

The presentation that speaks to the room.

The problem — 2 / 9

Presenting is speaking into a void.

Lectures and conferences still use static slides while the audience disengages in silence. Current tools (Mentimeter, Kahoot, Google Slides) force app-juggling, complicate logistics, and lose attention.

  • The presenter doesn't know if the audience is following.
  • Launching a quiz requires switching tools.
  • Learners cannot review what was just said.
  • Nothing is persisted after the session.

The solution — 3 / 9

One app, everything live.

Amphi centralizes slide delivery, quizzes, voice transcription, and notes in a single interface. Zero installation, zero learner accounts: a QR code is enough.
