Remember everything you learn.

Write down what you learned today, or just say it. Prismo organizes it for you and quizzes you on it, so it actually sticks.

iPhone, iPad & Android 8 languages

You learn something new almost every day. A chapter before bed. A podcast on the way to work. A conversation that changes how you see things. A week later, most of it is gone. Not because you weren't paying attention, but because nothing ever brought it back.

Prismo brings it back.

How it works

Three steps. A few minutes a day.

You do the learning. Prismo does the organizing and the remembering.

01
Capture

Write it down. Or just say it.

A few lines in your own words is enough. Type it, dictate it, or add a photo of a page or a PDF. No templates, no tags, no formatting.

02
Brain Sync

Prismo pulls out what matters.

AI reads your note and turns it into clear pieces of knowledge, each filed under the right topic. You see what it found and keep only what you want.

03
Review

Get quizzed before you forget.

Short quizzes written from your own notes come back over days and weeks, right when a memory starts to fade. Answer a few questions and it stays.

The science

Your brain is wired to forget. Prismo reminds it.

In 1885, psychologist Hermann Ebbinghaus measured how quickly we forget. Most new information fades within days unless you come back to it.

Spaced repetition is the fix. Each time you recall an idea just as it starts to slip, it fades more slowly than before, so the gaps between reviews can grow from days to weeks to months.

How the forgetting curve works

Memory over 30 days: without review it drops sharply and stays low; with spaced reviews on days 1, 3, 7 and 14 it stays high. Today Day 7 Day 14 Day 30 100% remembered Quick review With Prismo Without review

Questions? Answers.

What do I actually write?
Whatever you learned, in your own words. A few lines is plenty, for example: “Finished the chapter on the Agricultural Revolution. Farming made life harder for most people at first, not easier.” Prismo works out what's worth keeping and where it belongs.
How is this different from Anki or other flashcard apps?
You never make a card. Prismo reads your notes, writes the questions for you and schedules the reviews. You get the benefits of spaced repetition without spending hours building decks. Full Prismo vs Anki comparison
How much time does it take?
Most days, a few minutes: one short note and one quick quiz. Prismo tells you when something is due, so you never have to plan your reviews.
Can I check what the AI saves?
Yes. After each note, Prismo shows you what it found before anything is added. Untick what you don't want, and edit or delete any topic later.
What can I use it for?
Anything you want to remember: books, podcasts, classes, exam prep, a new language, things you learn at work, hobbies. If you learned it, Prismo can help you keep it.
Which devices and languages are supported?
Prismo runs on iPhone, iPad and Android. The app is available in English, French, German, Spanish, Italian, Portuguese, Japanese and Chinese.
What happens to my data?
Your notes are what Prismo uses to build your library and your quizzes. You can export everything at any time, and our Privacy Policy explains exactly how your data is handled.
