Formats and source materials
Make flashcards from lecture slides saved as PDF
Slides often contain fewer words than the explanation that accompanied them. A bullet such as factors affecting rate is not enough to reconstruct the lecture. Use a slide PDF for facts it actually states, and keep your permitted notes nearby when deciding whether a generated answer has enough support.
Prepare content slides rather than a title sequence
Place a small group of related teaching slides at the beginning of the excerpt. Opening slides, acknowledgments and repeated agenda pages can consume the free page window. If a PDF page holds several miniature slides, inspect whether the text is readable at all. A clear original export is preferable to a screenshot of a projected screen with tiny type.
Expand prompts without inventing explanations
Replace heading-only questions with a named relationship from the slide. A comparison table can support separate prompts for individual differences. A slide that shows only an unlabeled image cannot support a detailed textual answer by itself. Consult your own notes to edit the card, and keep any extra explanation distinguishable from information that was actually present in the PDF.
Worked example: two focused cards
These original editorial examples illustrate question design. They are not a live AI conversion or an official question bank. Use the wording and scope of your own source when editing a generated deck.
- Why can a slide heading be a weak card front?
- It names a topic without specifying which fact or relationship to retrieve.
- What should you check in a diagram-derived answer?
- Whether the stated direction and relationships match the actual arrows and labels.
Remove presentation artifacts from the deck
Look for repeated course titles, slide numbers and footer text that have become questions. Delete cards that test the presentation layout rather than the subject. Preserve qualifiers such as under these conditions when simplifying a bullet. Before studying a process diagram, check its arrows and labels visually; text extraction can list labels without retaining their spatial relationship.
Convert, check, then study
- Prepare a short PDF excerpt with the relevant text near the beginning. Upload it using the PDFtoDeck generator; check that the selected pages contain the topic you intend to study.
- Generate an AI draft, then read every question and answer against the source. Correct missing conditions, split overloaded answers and remove unsupported details before treating the deck as study material.
- Use Study now for a review session, download an Anki .apkg deck or CSV, or copy tab-separated text for Quizlet. Choose an export your destination can actually import and test a small set before moving a larger deck.
Limits, cost and document handling
Free generation includes 3 conversions per day, the first 5 PDF pages per conversion and up to 20 cards. Pro costs $3.99/mo or $29.99/yr. A generated deck can miss concepts or contain errors; use your source to decide what belongs in the final set.
The browser reads your PDF; clear English scans use on-device OCR. Extracted text is sent to the PDFtoDeck server and DeepSeek for AI generation. Process documents you have permission to use, keep sensitive information out of uploads and check the privacy policy for details.
Questions about this workflow
Can the tool recover what the lecturer said?
Only information in the extracted source can ground the AI draft. Add context from your own permitted notes rather than assuming the spoken explanation was captured.
What if slide bullets are too short?
Use a more complete source section, or edit the generated prompts alongside your lecture notes. Short bullets alone may not support a useful answer.
