PDF to Flashcards Conversion
Kardly.ai reads your PDF and automatically generates a complete set of question-and-answer flashcards from the content — no copying, no typing, no deciding what's important. Upload a lecture handout and within 2–3 minutes you have a study-ready deck built from your actual material.
This feature is designed for students who face the same problem every semester: you have the notes, but converting them into something you can actively study with takes hours. Biology lecture PDFs, law case summaries, history textbook chapters — whatever the subject, Kardly extracts the concepts that matter and turns them into flashcards optimised for active recall.
The cards aren't generic summaries of a topic — they're generated from the specific text you upload, so the questions reflect exactly what your course covers.
Real use case
Upload your Pharmacology lecture PDF (28 pages) on Monday morning. By the time your coffee is ready, you have 34 flashcards covering every drug class, mechanism, and side effect in the document.
- Dense lecture notes condensed into a clear, readable summary
- Key concepts and definitions highlighted automatically
- Read the full topic overview in under 5 minutes
- Structured output — not a wall of text
AI-Powered Study Summaries
Before you drill flashcards, you need to understand the structure of what you're learning. Kardly generates a concise, structured summary of your uploaded material — key concepts, main arguments, and important definitions, laid out clearly so you can see the big picture before going into detail.
Re-reading 40 pages of notes to find the important parts is not studying — it's a time sink. The AI summary does that work for you, condensing dense content into a version you can read in five minutes. This is especially useful for dense subjects like biochemistry, contract law, or macro-economics where the volume of material makes it easy to lose track of what actually matters.
Students who understand the structure of a topic before drilling details retain information more effectively. The summary is designed to give you that architecture before you start the flashcard review.
Real use case
Upload your 3,000-word Economics reading on Keynesian vs. Monetarist theory. Get back a 400-word structured summary covering the core positions, key economists, and policy implications — ready to skim before your seminar.
- Practice questions built from your specific course content
- Identify knowledge gaps before the exam finds them
- Generated automatically alongside flashcards — no extra steps
- Works for any subject that involves factual or conceptual knowledge
Automatic Quiz Generation from Your PDFs
Testing yourself is the single most effective study technique — and Kardly generates a quiz from your uploaded content automatically. The questions are built from your material, not from a generic question bank, so you're being tested on exactly what's in your lecture notes or textbook chapters.
Retrieval practice — the act of trying to recall information — has consistently outperformed re-reading and note-taking in learning research. The problem is that writing practice questions takes time most students don't have. Kardly eliminates that barrier: upload your PDF, and a set of practice questions is generated alongside the flashcards and summary.
The quiz is particularly useful a few days before an exam. Use it to identify your weak spots — the questions you can't answer confidently — and focus your remaining study time there rather than reviewing material you already know.
Real use case
Four days before your Anatomy practical, upload your muscle group notes. The quiz flags that you're consistently getting origin/insertion questions wrong. You spend the remaining study sessions focusing exactly there — instead of reviewing material you already know.

- Free tier: files up to 7MB (most lecture PDFs fall well within this)
- Paste text directly as an alternative to file upload
- Registered accounts unlock larger file support
Multi-Format File Support: PDF, DOCX, and TXT
Your study materials don't all come in the same format. Lecture slides get exported as PDFs. Your own typed notes are DOCX files. Reading extracts and study guides often come as plain text. Kardly supports all three — upload whichever format you have without converting anything first.
Free accounts support file uploads up to 7MB, which covers most lecture handouts, chapter PDFs, and standard DOCX note files. Registered accounts unlock larger file support for full textbook chapters, longer research papers, and multi-chapter uploads.
You can also paste text directly if you prefer — useful when you're working from a web article, a copied passage, or notes you've typed in another tool.
Real use case
Your lecturer shares slides as a PDF, but your own typed revision notes are a DOCX file. Upload both separately — Kardly generates flashcards from each without you touching any conversion tool.
- All flashcard decks, summaries, and quizzes saved automatically
- Organise by subject or custom folder for easy access
- Cross-device sync — desktop, tablet, and mobile
- Smart search across your full library
Study Library and Organisation
Everything you generate in Kardly is saved to your personal study library. Flashcard decks, summaries, and quizzes are organised by subject or folder so you can return to them at any point — on any device. Start a session on your laptop, pick it up on your phone during the commute.
The library is particularly useful across a full semester. Rather than generating new flashcards the week before each exam, you build a library of decks throughout the term and use them for scheduled review sessions. This is the foundation of spaced repetition: returning to material at intervals rather than cramming it once.
Search across your entire library to find a specific topic quickly, or browse by subject group to see everything you've generated for a particular course.
Real use case
By week 8 of your Biology semester, your library has 12 flashcard decks covering cell biology, genetics, and ecology. In exam week you work through each deck in spaced sessions instead of starting from scratch — saving hours of prep time.
- Flashcards, summary, and quiz generated in 2–3 minutes
- No queue, no waiting email — results appear immediately
- Fast enough to become part of a regular post-lecture routine
- Consistent speed regardless of document complexity
Instant Results — 2–3 Minute Processing
From upload to flashcards, summaries, and quiz — the full output is ready in 2–3 minutes. There's no waiting, no queue, no 'we'll email you when it's ready.' Upload your PDF and the study materials are there before you've had time to make a plan.
Speed matters when you're trying to build a consistent study habit. If generating flashcards requires a 20-minute wait, you'll do it once. If it takes 2 minutes, you'll do it after every lecture. That frequency is what turns a useful tool into a study habit.
The processing time stays consistent regardless of file size within supported limits — a 10-page handout and a 40-page chapter both return results in the same window.
Real use case
You finish a 9am lecture, open Kardly on your phone, upload the PDF your lecturer just posted. By 9:08am you have 22 flashcards. You flip through them on the walk back to your accommodation.
- Full-text search across flashcards, summaries, and quizzes
- Find content from any subject or session instantly
- Useful when topics overlap across multiple courses
- Works on the same account across all devices
Smart Search Across All Your Study Materials
As your library grows across a semester, finding a specific flashcard deck or summary becomes increasingly important. Kardly's search works across all your generated content — type a keyword and see matching decks, summaries, and quiz sets from any subject.
This is more useful than it sounds when you're dealing with overlapping topics across courses. Searching for 'oxidative stress' might surface notes from your Biochemistry lecture, your Clinical Medicine reading, and a research paper summary — all in one place.
Real use case
You remember covering mitosis in two different modules this semester but can't recall which deck it was in. Search 'mitosis' — both decks surface immediately, along with the quiz set from your Genetics reading.
- Instant sync across desktop, tablet, and mobile
- No manual export or transfer — everything just appears
- Study in short sessions across multiple devices throughout the day
- All progress and history preserved across devices
Real-Time Sync Across All Devices
Your flashcard decks, summaries, and quiz history are synced across every device on your account. Upload a PDF on your laptop in the library, review the flashcards on your phone on the bus home, pick up the quiz where you left off on your tablet that evening.
For students, device continuity matters. Study sessions don't happen in one place — they happen between lectures, during commutes, in short windows throughout the day. Real-time sync means none of that time is wasted waiting for content to appear on a new device.
Real use case
You upload notes on your university computer, do a 10-minute flashcard session on the bus using your phone, and continue the quiz on your laptop that evening — all within the same seamless session.
Why Kardly beats manual flashcard creation
The old way of making flashcards by hand works — it just takes most of your available study time. Here's the honest comparison.
Manual Flashcard Making
60–90 min per PDF
A typical 20-page lecture PDF takes over an hour to convert into usable cards by hand.
You decide what matters
Without guidance, students often focus on the wrong concepts and miss examinable content.
Hard to stay consistent
Few students maintain a flashcard habit when the setup time is this high.
No summaries or quizzes
Manual flashcards are just flashcards — you have to create summaries and tests separately.
Can't scale to exam season
When you have 6 subjects to prepare for, manual prep becomes impossible.
Kardly.ai
2–3 minutes per PDF
Upload and have a complete flashcard deck ready before you've finished making your coffee.
AI identifies key concepts
The AI reads your material in context and extracts what actually matters — not just keywords.
Effortless habit
When setup takes 2 minutes instead of 90, you do it after every lecture automatically.
Flashcards + summary + quiz
Everything generated at once. Flashcards to drill, summary to understand, quiz to test.
Scales to any workload
10 subjects or 1 — the time per document stays the same. Exam season doesn't change the equation.
Students using Kardly save 5+ hours per week on study preparation. That time goes back into actual learning. See what's included in each plan →
