From PDF to review-ready deck in 4 steps

1. Copy the text from your PDF

Open the PDF on your phone or computer and select the text you want to study, lecture slides, a textbook chapter, research article, or exam review notes.

2. Paste it into Flashi

Paste the copied text into the create-deck field. No file upload needed, Flashi works directly from pasted or typed text.

3. AI writes the flashcards

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

4. 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.

Can I upload a PDF directly to Flashi?

Not as a file. Flashi does not accept PDF uploads. Instead, open your PDF, select and copy the text you want to study, and paste it into Flashi's create-deck field. From there, the AI does the rest.

How does Flashi turn a PDF into flashcards?

Copy the text from your PDF and paste it into Flashi. The AI reads the pasted text, 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. Just make sure you can select and copy the text. Scanned PDFs without OCR won't let you copy real text, so run them through an OCR tool first.

How many flashcards do I get per PDF?

It depends on how much text you paste in. Flashi's free tier includes one AI generation of up to 15 cards, so paste in the section you most need to study first. You can always trim, edit, or regenerate after.

Is the PDF flashcard generator free?

Yes. Flashi is free on iOS. The free tier includes one AI generation (up to 15 cards) and 2 decks total, plus spaced repetition, Anki import, and deck sharing.
