From PDF to review-ready deck in 4 steps

1. Share your PDF with Flashi

Lecture slides, a textbook chapter, research article, or exam review — anything you can open on your phone.

2. AI extracts the flashcards

Flashi reads the content and writes question/answer pairs focused on the concepts most likely to appear on an exam.

3. Review with spaced repetition

The SM-2 algorithm schedules each card at the right interval. Cards you know wait weeks; cards you struggle with come back tomorrow.

4. Refine as you go

Edit any card, merge decks, or regenerate weaker cards from the same PDF. Your deck improves with you.

How does Flashi turn a PDF into flashcards?

Flashi reads the text content of your PDF, identifies the key concepts and facts, and generates question/answer pairs optimized for recall. You get a real, editable deck — not a wall of copied sentences.

What kinds of PDFs work best?

Any text-based PDF works: lecture slides, textbook chapters, study guides, research papers, or exported notes. Scanned PDFs without OCR produce weaker decks — if your PDF is a photo of pages, run it through an OCR tool first.

How many flashcards do I get per PDF?

It depends on the density of the source. A single lecture slide deck might produce 20–40 cards; a full textbook chapter can produce 100+ cards. You can always trim or merge after generation.

Is the PDF flashcard generator free?

Yes. Flashi is free on iOS — deck generation, spaced repetition, Anki import, and audio review are all included.
