A step-by-step workflow for iPad and Apple Pencil users who want to turn annotated PDFs into a real active recall system.
iPads with Apple Pencil are excellent for annotating PDFs and taking handwritten notes. The problem: annotated PDFs don't automatically become retrievable knowledge. Students can spend hours making beautiful GoodNotes annotations and never revisit them for active recall. The workflow below closes that gap — turning your annotation session directly into a spaced repetition deck.
Annotating and highlighting PDFs feels productive. It requires focus, your notes look organised, and you finish a session feeling like you've studied. But annotation is a passive activity. You're processing information — not retrieving it. And retrieval is what drives long-term retention.
Students who use GoodNotes or Notability can spend hours producing colour-coded, beautifully structured notes. The problem is that those notes often sit untouched between lectures. Research on the testing effect consistently shows that rereading your own notes — even well-made ones — is one of the least effective ways to consolidate memory compared to active recall practice.
The iPad annotation workflow is excellent for initial engagement with material. It just needs a second stage: generating flashcards from what you've annotated, so the act of writing notes feeds directly into a review system. Without that second stage, you're doing half the work.
You don't need much. Four components cover the full workflow:
Your primary annotation environment. GoodNotes 6 and Notability are the most popular choices for annotation and handwritten notes. PDF Viewer is a lighter option if you prefer working directly with PDFs without a notebook structure. Any of the three exports clean PDF files that work with the rest of this workflow.
Use it freely for diagrams, circling key terms, and visual connections. Just be aware (see below) that handwritten content is embedded as an image in exported PDFs — the AI will not extract it. The Pencil is still highly valuable for visual organisation and initial processing.
Both GoodNotes and Notability support exporting a notebook page or full notebook as a PDF. This preserves the original typed text content of lecture slides and documents, along with any typed text annotations you've added. This exported file is what you upload to StudyCardsAI.
Upload your exported PDF and StudyCardsAI reads the text content — lecture slides, reading passages, typed annotations — and generates a flashcard deck automatically. Review cards in-app or export to Anki if you prefer Anki's review algorithm.
Run this once per subject per week and your annotation sessions will automatically produce a review deck:
Open your lecture slides or reading in GoodNotes or Notability. Highlight key terms, underline definitions, draw diagrams with Apple Pencil. Study this as you normally would. Don't change your annotation habits yet.
Before exporting, switch to the text tool and type your most important margin notes as text boxes. GoodNotes supports typed text annotations. This is the step most iPad users skip — and it's the one that most improves AI card quality. If your insight is worth writing, it's worth typing.
In GoodNotes: tap Share → Export → PDF. In Notability: tap the share icon → Export → PDF. Save to Files or share directly. The export takes a few seconds and produces a standard PDF with all text content intact.
Go to StudyCardsAI in Safari on your iPad. Upload the exported PDF. The AI reads the full text content and generates a draft deck — typically within 30-60 seconds for a standard lecture PDF.
Delete low-priority cards (administrative content, page numbers, context that doesn't need memorising). Add any key points from your handwritten notes manually if they didn't make it in. A trimmed deck of 20-30 high-yield cards is better than 80 cards of mixed quality.
StudyCardsAI is web-based — open it on your iPhone during your commute, between classes, or while waiting. Smaller screen, more portable, forces focus. Save iPad review sessions for when you have 30+ minutes and want to go deeper.
Being honest about this saves frustration. Here's what the pipeline handles well and where the limits are:
The workaround is simple: use the typed text tool in GoodNotes for any insight you want the AI to see. Reserve Apple Pencil for visual organisation (diagrams, arrows, circles) and switch to the keyboard for margin notes that contain actual content worth testing yourself on.
A few habits that compound over a semester:
Open lecture slides on the left panel, your GoodNotes notes page on the right. This lets you annotate and build your own summary simultaneously without switching apps. Works well on iPad Pro and iPad Air in landscape mode.
As you work through material, add any question that you'd expect on an exam to a dedicated last page. When you export and upload the PDF, these questions become your highest-priority flashcard prompts. This habit alone dramatically improves card quality over generic AI generation.
Batch the upload-and-generate pipeline once per week per subject rather than after every lecture. Weekly batching gives you a broader set of content to generate from, reduces repetition in the deck, and takes less total time than running the workflow daily.
iPad is for creation. iPhone is for review. The smaller screen and portability of an iPhone makes it better suited to the short, frequent review sessions that spaced repetition requires. Keep iPad annotation sessions separate from flashcard review sessions.
For more on turning document formats into flashcards, see the PDF to Flashcards guide and the Notes to Flashcards guide. If you use Notion alongside your iPad workflow, the Notion to Flashcards Pipeline covers that integration. For exam-period organisation, the Finals Survival Kit has a complete study schedule framework.
Upload your annotated PDF and StudyCardsAI generates a review-ready deck in under a minute. Works in Safari on iPad.
Yes. Export your GoodNotes notebook as a PDF (Share → Export → PDF) and upload directly to StudyCardsAI. The AI reads the text content of the PDF — any typed text, text boxes, or selectable text from the original document. Handwritten Apple Pencil content is not extracted automatically.
Yes — StudyCardsAI is web-based and works in Safari on iPad. You can upload PDFs and review flashcards entirely on iPad. Many students upload from iPad and then review on iPhone during commutes.
Typed notes with clear structure produce higher-quality AI-generated cards. Annotated PDFs work well for the base text, but if you're adding insights in the margins, type them as text boxes rather than handwriting so the AI can read them.
Any iPad with Apple Pencil support works well for the annotation workflow. The iPad Air (M1 or later) offers the best balance of performance and price for students. iPad Pro is excellent but not necessary for note-taking. The iPad mini is highly portable for review sessions.
