How narrated maths slideshows work

A narrated slideshow is a maths explanation split into short slides, where each slide carries one idea and is read aloud while it is on screen. Reading a long worked solution in a textbook asks you to hold several ideas in your head at once. A narrated deck removes that load: the slide shows only the current line of working, and the voice explains why that line follows from the one before it. You can pause on any slide, step backwards, or jump to a particular step from the slide overview.

There are two ways to start a deck. In problem mode you type a question, for example a quadratic to factorise or a function to differentiate, or attach a photograph of it. The platform breaks the solution into ordered steps, sets the key working for each step, and narrates the reasoning. In notes mode you upload your own material, such as a set of lecture notes, a multi-page PDF, or a series of slide snapshots, and the platform builds the deck directly on top of your pages. Your original slides stay visible and are narrated in sequence, so a lecture you were given in class can be replayed as a spoken presentation.

Audio is generated per slide, which is what allows the voice to stay in step with the slide: when a slide appears, its narration begins, and when the narration ends the deck advances. Language can be switched between English and Mandarin for the same deck, so a student can listen once in one language and again in the other. Decks you want to revisit can be saved to your library and reopened later with their slides and audio intact.

Each slide has a plain-language explanation alongside the working, so the content stays readable even with the sound off. Mathematics is rendered properly rather than as plain text, which matters for fractions, powers, and algebraic manipulation. The result is a study format built for revision: short, repeatable, and easy to stop the moment something needs a second look.
