Turn lecture slides
into flashcards.
For medical and health-science students studying their own course slides: preview a small source-backed sample before signing up, then upload a readable PDF or PowerPoint, inspect the drafts, keep the cards you want, and practice with quizzes and spaced-repetition reviews. Every card Passal makes shows the line it came from, or Passal leaves it out.
Try a short sample before signing up
This sample uses the original cardiac-output-lecture-07.pdf from the test lecture. These four example cards are the same source-backed cards shown in Passal’s homepage demo; they are examples, not a promise that every upload produces these exact cards.
What is a normal ejection fraction?
about 55 to 70 percent

“A normal ejection fraction is about 55 to 70 percent.”
What does greater stretch of cardiac muscle fibers produce?
a more forceful contraction
Check the source · page 4
“Greater stretch of cardiac muscle fibers produces a more forceful contraction.”
What is mean arterial pressure?
cardiac output multiplied by total peripheral resistance
Check the source · page 8
“Mean arterial pressure equals cardiac output multiplied by total peripheral resistance.”
One-question self-check
Try it: What is the stated normal ejection fraction?
Answer: about 55 to 70 percent.
Source · page 3: “A normal ejection fraction is about 55 to 70 percent.”
This is a short editorial self-check, not a quiz generated by Passal.
How a mismatched draft is handled
Test draft (deliberately mismatched; not a customer mistake): “Increased preload decreases stroke volume when contractility is unchanged.” The quote does not occur on the cited slide, so Passal’s quote-grounding check rejects it as “quote not in page.”
Corrected test draft: “Increased afterload decreases stroke volume when contractility is unchanged.” This exact passage appears on page 5 and passes the quote check. A matching quote only shows what this lecture says; it does not prove the lecture is medically correct, current or complete.
How do I turn lecture slides into flashcards?
- Upload the lecture. Add a PDF or PowerPoint (
.pptx) to a course. Text and Markdown files work too. - Look over the drafts. Passal makes flashcards from the lecture, plus quiz questions when the lecture supports them. Keep the ones you want, and edit or delete the rest. Only cards you keep go into your reviews.
- Start reviewing the same night. Spaced repetition schedules each card, and the Today screen shows what’s due.
Which files work?
- PDF and PowerPoint. Upload the file your instructor posted. If you can select the text in the PDF, Passal can read it.
- Scanned slides need text. A scan with no selectable text won’t work. Use the original PowerPoint or a text-based PDF instead.
- Recorded lectures. Upload the transcript (
.vtt,.srtor.txt) along with the recording. - Notes. Plain text and Markdown files work like a lecture.
How do I know a card matches my lecture?
Every card Passal makes shows the line from your slide it came from, with a link to that spot in the lecture. If Passal can’t match a draft to your lecture, it leaves the draft out instead of guessing. If you edit a card, Passal marks it, because your edit may no longer match the slide.
A source quote lets you check what your lecture said. It does not establish that the lecture is medically correct, current or complete, or that the cards cover everything on your exam. Review drafts against your course material.
Does Passal make quizzes too?
Sometimes. Passal adds quiz questions only when a lecture has material it can turn into a fair multiple-choice question, so many lectures get cards but no quiz. When there is one, pick the wrong answer and Passal shows the right one with the line from your slide. Cards you mark Again and questions you miss wait in Recovery until you get them right on a later day, each with its lecture and page.
Can Passal plan my reviews around an exam?
The Today screen shows your due cards and your next exam. Link your calendar, tag the exam event in Passal, and Passal moves your lecture cards’ reviews earlier so they land before it. Adding an exam date to a course on its own only displays it; it doesn’t change the schedule.
