One document, a reviewable deck

turn a PDF into flashcards, then keep reviewing.

A long reading is difficult to revisit as one block. biu turns a PDF into a summary and a flashcard deck, giving you smaller prompts to inspect and review over time.

The original PDF remains the reference; generated summaries and cards are a study layer on top.

How does PDF to flashcards work?

A PDF-to-flashcards workflow identifies study material in a document and drafts question-and-answer cards from it. In biu, you add the PDF, inspect the generated summary and cards, and then review due cards through the same daily spaced-repetition quiz used for other sources.

best fit

use PDFs that contain material you need to recall

The workflow is designed for study material, not for replacing careful reading or professional review.

Course readings

Turn key concepts from assigned material into prompts you can revisit after the first read.

Lecture handouts

Convert structured notes and explanations into a compact deck for later practice.

Study guides

Use an existing revision document as the source for questions rather than rewriting every card.

Reference material

Create recall prompts for terminology and facts while keeping the PDF available for context.

four steps

a responsible PDF-to-review workflow

A short inspection step between generation and review makes the deck more dependable.

  1. 01

    Add the PDF

    Choose one document with a clear study purpose. If your material exists as separate photos of notes, biu accepts those as another supported input.

  2. 02

    Read the generated summary

    Use the summary to see how biu interpreted the document and to notice missing context before reviewing individual cards.

  3. 03

    Inspect important flashcards

    Compare precise facts, formulas, definitions, and claims with the original pages. Generated cards are drafts, not a replacement for the source.

  4. 04

    Review cards when they are due

    Answer cards in the daily quiz. Correct answers increase the interval before the next scheduled review.

quality check

what to inspect before studying

The usefulness of a generated deck depends on both the source and the review you give the output.

Start by checking whether each card asks one clear question. Split cards that bundle several ideas, and preserve enough context that the answer still means the same thing outside the paragraph it came from.

Then verify details where accuracy matters: units, negatives, exceptions, names, dates, citations, and terminology. If a PDF is ambiguous or visually complex, return to the relevant page instead of assuming the generated card captured everything.

quick answers

frequently asked questions

Can biu create flashcards from a PDF?

Yes. Add a PDF and biu generates a summary and a deck of flashcards from its study material.

Should I check AI-generated flashcards?

Yes. Compare important cards with the original PDF, especially definitions, formulas, dates, names, and context-dependent claims.

What happens after the cards are generated?

The cards can become part of your daily quiz. biu schedules them using your review history and increases intervals after correct answers.

Does biu publish a PDF size or page limit?

This page does not state a size or page limit because those limits have not been approved for publication. Beta participants should follow the limits shown in the app.
