lrnos vs Anki: the Anki alternative that builds the deck for you
same spaced repetition science. one of you still has to make the cards.
anki and lrnos both lean on FSRS, the same spaced repetition scheduler, so the memory science underneath is genuinely shared. the difference is where the work lands. anki is a free, open-source card engine: you decide what goes on every card, build or download decks, and tune the system to taste. that control is the whole point, and for a lot of people it is exactly right.
lrnos starts from your actual course materials. you upload your PDFs, slides, documents, and video or YouTube links, and lrnos reads them, maps every concept into an ordered path, writes practice questions from that content, and schedules reviews with FSRS so you do not forget. if you already own the material and want full coverage plus retention without building a deck by hand, that is the gap lrnos fills.

where Anki is genuinely strong
- free and open-source on desktop and android, with the same FSRS scheduler lrnos uses, and AnkiMobile on iOS is a one-time paid app rather than a subscription.
- a huge shared-deck ecosystem on AnkiWeb. for popular subjects like languages or medical boards, someone has often already built a high-quality deck you can download in minutes.
- deeply customizable: card templates, add-ons, custom note types, and fine-grained scheduling settings let power users shape it into almost anything.
- works fully offline and has detailed review statistics, and it has been proven over many years by a large, dedicated community.
where lrnos is the better fit
- no deck-building. you upload your own PDFs, slides, documents, and video or YouTube links, and lrnos writes the cloze and multiple-choice questions from them for you.
- ordered full-syllabus coverage. lrnos maps every concept into a path and tracks the percent you have covered, so you are not guessing whether a deck is complete.
- a daily plan in roughly 15-minute sessions that tells you exactly what to study today, plus streaks and 1 to 3 stars per lesson you can replay to raise.
- bilingual by design in english and egyptian arabic with full right-to-left support, and it explains why each answer is right before moving on.
which one should you use
pick anki if you want maximum control and minimum cost, you are happy building or downloading decks, or a strong shared deck already exists for your subject. it is free on desktop and android, fully offline, endlessly customizable, and the FSRS scheduling is excellent. for people who enjoy crafting their own cards, anki is hard to beat.
pick lrnos if you already have your own course materials and want coverage and retention without the setup. lrnos turns your files into an ordered path, generates the questions for you, schedules them with FSRS, and tells you what to study each day. it is free to start with no card, so the honest move is to try both and keep whichever matches how you actually study.
lrnos is free to start with no card and competitively priced paid plans. anki is free and open-source on desktop and android, with AnkiWeb free in the browser; its official iOS app, AnkiMobile, is a one-time paid purchase (as of 2026, check their site).
frequently asked questions
Is lrnos a good Anki alternative?
yes, if you do not want to build flashcards by hand. lrnos uses the same FSRS spaced repetition scheduler as anki, but it reads your own PDFs, slides, and videos and writes the questions for you, then maps an ordered study plan. anki gives you more control and a free offline app; lrnos saves you the deck-building.
Does lrnos generate flashcards from my PDFs automatically?
yes. you upload your PDFs, slides, documents, and video or YouTube links, and lrnos reads them and generates practice questions, cloze fill-in-the-blank and multiple choice, directly from your material. anki does not auto-generate cards from your files; you make or import them yourself.
Do lrnos and Anki use the same spaced repetition algorithm?
both use FSRS, the free spaced repetition scheduler, which is the default for new collections in recent anki versions. so the underlying memory science is the same. the difference is that lrnos also creates the questions and an ordered plan, while anki schedules cards you supply.
Is Anki free, and what about lrnos pricing?
anki is free and open-source on desktop, windows, mac, linux, and android, and AnkiWeb is free; the official iOS app, AnkiMobile, is a one-time paid purchase (as of 2026, check their site). lrnos is free to start with no card and has competitively priced paid plans.
Can lrnos cover a whole syllabus instead of single topics?
yes. lrnos maps every concept in your uploaded materials into an ordered path and tracks the percent you have covered, so you get full-syllabus coverage in order. with anki, coverage depends on whichever cards you or a shared deck include.
