The problem
Clear explanations feel like learning. Remembering is the hard part.
Most tools stop at a tidy explanation, the part that is easy to nod along to and just as easy to forget. Prism is built around what makes knowledge last: recalling it in your own words, connecting it to what you already know, and noticing where your understanding quietly breaks.
How it works
Four steps, calm and unforced.
You lead. Prism adapts.
Point
Aim your camera at an object or a scene. Prism works out what it is and offers a few lenses to explore it.
Tune
A dial for wording, from "explain like I'm 10" to technical, plus an "I don't understand" button that re-explains more simply.
Explain it back
Say the idea back in your own words, typed or spoken. Prism reflects the gaps. Only a real explanation counts as mastered.
It sticks
Concepts you have seen but not yet mastered resurface on a spaced schedule, so understanding turns into memory.
What makes Prism different
Designed for understanding that lasts.
Understanding you can prove
A "got it" tap records a feeling, not a fact, so it never marks mastery. Only explaining an idea back in your own words does.
Your personal knowledge map
Every explanation adds concepts to a personal graph that tracks what you know and links new ideas to ones you already learned.
Explained at your level
A simplicity dial changes how Prism explains without dumbing the topic down. It adapts wording and prior knowledge, never a "learning style."
Built for remembering
Spaced review resurfaces concepts you have seen but not yet mastered, because recalling an idea is what makes it stick.
Curiosity, not pressure
You point at what caught your eye, so the question pulling you forward is your own. No gamified pressure, no dark-pattern streaks.
Take your learnings on the go
Your account syncs your knowledge map across your devices, so everything you've learned travels with you, so you pick up right where you left off, anywhere.
The evidence
Built on research, not vibes.
Every design choice traces to published learning science. Its strongest foundations, recall practice, spacing, self-explanation, and starting from what you already know, are among the most established results in the field.
In the interest of trust
What Prism will not do.
No "learning styles"
The idea that matching a visual or auditory "style" improves learning is not supported by evidence, so we do not claim to detect or match one. We adapt wording and prior knowledge instead.
No guaranteed outcomes
Learning is personal and no app can promise a result. We make no medical or guaranteed-outcome claims. We give you methods that have held up for decades.
No dark-pattern streaks
Rewards can crowd out the curiosity that makes learning last, so streaks and counters stay small and optional, never engineered to keep you hooked.
