Coming soon to iPhone and Android

Turn the PDF you keep putting off into a lesson you'll finish.

Drop in lecture slides, a paper, a YouTube link or one question. Saripati builds an illustrated lesson, quizzes you in short rounds, and remembers what you still don't know.

Saripati

Start with what you already have

A 40-page PDF from your lecturer. A slide deck. A lecture on YouTube. A paragraph you copied. Or one question you've always wondered about.

  • PDF
  • Word
  • PowerPoint

  • YouTube link
  • One question

i

Start with what you have

Plate I. Typing a question into Create: what would happen if you fell into a black hole?

ii

Saripati

It becomes a lesson with pictures

Saripati breaks the reading into short slides, one idea each. The slides come with pictures drawn for their idea: a labelled diagram, a before and after, an analogy you can see. Real photos where the real object matters, charts where there's data.

  • Black hole slide illustration
  • Fireworks chemistry slide illustration
  • Biology slide illustration
  • Physics slide illustration
  • Vaccines slide: macrophages and neutrophils
  • Engineering slide illustration

Then you get to play with it

Some ideas only click when you move them. Drag a clock toward a black hole. Lower the sun and watch the sky turn red. Launch a firework made of copper instead of strontium.

Each visual asks you to predict first, then lets you try it. When the result lands, Pati lights up with you.

Play with the idea

Plate III. Two clocks near a black hole. Move one closer and it ticks slower.

Saripati

Practise in rounds, like a game

Flashcards for what you need to remember. Quiz rounds that check whether you can reason with it. Miss a question and it comes back before the round ends.

When you think you've got it, explain the idea back in your own words. Saripati tells you what you left out.

Practise in rounds

Plate IV. Round two of the black hole quiz.

Saripati

It remembers what you don't know

Every answer you give updates your knowledge map. Solid ideas get a check. The shaky ones stay marked, and Saripati picks your next step for you.

Saripati remembers what you don't know, and makes practising it feel like a game.

It remembers your gaps

Plate V. The knowledge map after one session, with the next step picked.

What can I put in?

PDFs, Word and PowerPoint files, pasted text, YouTube links, or a single question. Scanned PDFs without selectable text don't work yet.

Which phones does it run on?

iPhone first. Android follows.

Do I have to make the flashcards myself?

No. Every lesson comes with its own flashcards and quiz rounds, built from the same slides.
