Immediate value
Process flow: Flashcards Blueprint -> Lecture PDF upload -> Q/A generation -> Export -> Import into Anki
Before (raw PDF)
40 dense slides, mixed bullet points, formulas, and side examples. No clear Q/A pairs, no import format.
After (Anki-ready)
One flashcard format, every lecture
Clean pairs, not raw bullets
Paste or CSV-import into Anki
5-step workflow
Define the tab once: a clean list of Q: ... A: ... pairs, short answers, one concept per card. Save it so you never redo this prompt.
Drop in the PDF. Heyblocks extracts the text from the slides without you copy-pasting anything.
Heyblocks applies your Blueprint and produces a structured Q/A list covering definitions, formulas, and recall prompts.
Quickly skim for edge-case cards, fix domain terminology, then copy the list or export as text / CSV.
In Anki: File → Import. Map the first column to Front, second to Back of a basic note type. Deck ready.
Why Heyblocks fits
The actual problem with "AI flashcard from PDF" workflows is consistency. Prompt-only tools give you a different structure every time, which breaks your Anki deck format.
With Heyblocks Blueprints, your lecture-to-Anki pipeline runs in the same shape every week. Same Q/A style, same sections, same import format.
Anki import
The cleanest path is a plain text / CSV import. Anki reads it natively and maps fields to your note type.
Example export format (tab-separated)
What does Bayes' theorem compute? Posterior probability given prior and likelihood. Time complexity of binary search? O(log n). Definition of entropy in information theory? Expected information content of a random variable. Newton's second law? F = m · a
In Anki: File → Import, pick the file, set Field separator: Tab, map column 1 to Front, column 2 to Back, choose or create your deck, click Import. Done.
FAQ
Set up a Flashcards Blueprint in Heyblocks that defines the Q/A style, upload your lecture PDF, generate the Flashcards tab, export the output, and import it into Anki as a basic note type. Reusing the same Blueprint keeps every deck consistent.
Heyblocks produces flashcard-ready output that you copy or export as text / CSV. Anki's built-in importer handles this natively. For most users, importing a CSV is faster and more flexible than juggling .apkg files.
Yes, as long as the PDF text is selectable. Formulas, definitions, and domain terms are preserved. Review the tab once before importing to catch any PDF extraction quirks.
Text-based lecture PDFs (exported from PowerPoint, Keynote, LaTeX, Google Slides) work best. Pure scans without embedded OCR text need to be OCR'd first. If you have a lecture recording instead, you can use the lecture-recording workflow.
Yes. You can keep one universal Flashcards Blueprint, or build per-subject Blueprints (for example: one for bio with more definition cards, one for math with more formula cards). Switching Blueprints is instant.
Yes. The free plan includes enough generations to test the full lecture-PDF-to-Anki workflow. No credit card required to start.
