A four-second hello from Vesper, one of the voices pupils can choose for Ace in the app.

The closest thing to a real tutor.

Most study apps make you type a question and wait for a reply. Ace runs on OpenAI’s latest realtime voice models, built for live, spoken conversation. So a lesson is a conversation, not a search.

What a lesson is like.

  1. Say what you’re stuck on.

    Pick a topic, or just say it out loud. “I don’t get simultaneous equations” is a fine place to start.

  2. Ace asks, you think.

    It asks the next question and lets you do the working, the way a good tutor does.

  3. It draws as it explains.

    Working, diagrams and graphs appear on a live board while Ace talks you through them.

  4. Stuck? It tries another way.

    A new example, a smaller step, a picture instead of words.

  5. Snap & Mark.

    Photograph a handwritten answer and get feedback in seconds.

  6. Next time, it remembers.

    Ace picks up where you left off, so nobody starts from scratch.
