What is Limbiks?
Limbiks is an exam preparation tool that turns PDFs, slides and videos into ready-to-study flashcard decks. Limbiks generates flashcard decks from PDFs, slide decks, Word documents, photos of notes, YouTube videos and Wikipedia pages, then provides spaced repetition, practice tests, study guides and one click Anki sync.
Limbiks is a study tool built around a single premise: the slowest part of exam preparation is making the cards, not learning them. The service ingests source material and returns a finished deck. Upload a PDF, a PowerPoint deck, a Word document, or a photo of handwritten notes, and Limbiks reads the content and produces a set of question and answer cards within seconds. It also accepts YouTube videos and Wikipedia articles as sources, which helps when a course has no clean textbook. The workflow is intentionally short. A file picker sits at the top of the homepage, with a page or slide selector that controls how much of a document gets processed. Generated cards appear in a preview before you commit to studying them. From there, Limbiks doubles as a study environment: spaced repetition scheduling, hints and explanations on individual cards, image occlusion cards built from figures extracted out of your files, multiple choice question banks, full practice exams with score reports, and AI generated study guides with adjustable difficulty. Cards can be exported for use elsewhere or synced to Anki with a single click, and decks can be downloaded in formats that import into Quizlet, Cram, Tinycards and similar tools. The audience is students first. The homepage lists foreign language, history, medicine, computer science and biology among the subjects it is used for, and support for 21 languages including Chinese, Japanese, Korean, Spanish, German and Polish makes it viable for language learners and for students studying in a second language. Anyone who already maintains an Anki library can treat Limbiks as a card factory rather than a replacement for their existing workflow. Competitively, it sits between generic AI chat tools that can produce quiz questions on request and dedicated spaced repetition software that does not generate content. Limbiks tries to own both ends. The free tier is workable for casual use, but the ten uploads per month and five page limit per file mean heavy course loads will push most users toward Pro.
