Serpaix vs Anki

Anki drills decks. Serpaix generates them from the work you already did.

Anki is the classic open-source spaced-repetition program: plain flashcards, the SM-2 scheduler (with FSRS available as an option), a vast shared-deck marketplace, and near-total control — at the cost of a tool that only knows what you put into it. Serpaix uses FSRS-4.5 as its default scheduler and auto-generates cards from the notes, PDFs and meetings you capture, so the study material is your own knowledge instead of a downloaded deck.

In short: Serpaix and Anki are both tools for organising what you know, but they optimise for different things. Serpaix is a local-first personal AI operating system — capture, knowledge graph, search and AI chat run on your own Windows PC, with cloud sync, mobile apps and enterprise SSO on the roadmap. Choose Serpaix if: your study material comes from your own work — notes, documents, meetings — and you want flashcards generated for you, with capture, a knowledge graph and grounded AI chat around the same loop. Choose Anki if: you want a dedicated flashcard engine with a 20-year track record, a huge shared-deck marketplace and native mobile apps, and you are happy building decks by hand or installing add-ons.
