What one hour looks like

A fair comparison is not only about session length. It is about what the hour actually contains. With Preply, one hour is scheduled tutor time. With Ozzz, one hour can hold conversation, voice practice, tap-to-reveal meaning, pronunciation, and tools.

  • Preply: one scheduled hour with a tutor
  • Ozzz: one flexible hour of conversation and tools
  • The product shape of the hour is different

Why Ozzz is different from general voice assistants

ChatGPT, Claude, and Gemini all have voice features. Ozzz differs because voice is treated as a persistent practice and tool-control layer. The floating microphone is draggable, resizable, and mode-aware, and the toolbar can minimize and expand while keeping controls reachable.

  • Voice is part of the practice surface, not a separate mode
  • Draggable mic helps one-handed use
  • Resizable mic improves touchability without bulky chrome

Why Ozzz is different from Duolingo

Duolingo is useful for structured, bite-sized, game-like lessons and habit loops. Ozzz is built for unscheduled, open-ended immersion that can keep reappearing across the waking day.

  • Duolingo fits lesson-loop practice
  • Ozzz fits real-life immersion moments
  • Both can be useful for different goals

Why Ozzz is different from Preply

Preply is valuable for human tutors, scheduled lessons, feedback, and accountability. Ozzz is different because it lets the learner return to immersion without booking each practice block as paid tutor time.

  • Preply = human feedback and scheduling
  • Ozzz = repeated return to immersion
  • 10 hours per day scales to 70 hours per week

Ozzz features that change the experience

Progress for calculations is spoken and persisted as first-class assistant messages. Saved conversations remain useful even when replies are off.

  • Tap-to-reveal meaning stays in context
  • Pronunciation works on both speakers
  • Progress bubbles persist in the chat history
