Limbiks

Limbiks turns study material into flashcards and related practice resources. Students can upload PDFs, PowerPoint presentations, Word documents, text files, JPEG or PNG images, or start from a YouTube video or Wikipedia article. Generated cards can be reviewed in the built-in study tool, edited, downloaded for use in other flashcard apps, or synced to Anki through AnkiConnect. The service also supports multiple-choice questions, practice tests, spaced repetition, study guides, hints and explanations, and image-occlusion generation. Its Free plan supports 10 uploads or generations per month, up to 5 pages or slides per upload, 100 multiple-choice questions per month, 10 practice tests per month, and 25 image-occlusion generations. The Pro plan costs $5 per month and raises those limits while adding learning objectives, custom instructions, AI-generated study guides, unlimited multiple-choice questions and practice tests, up to 100 questions per practice test, hints and explanations, and 500 image-occlusion generations per month. Limbiks works best with English but supports 21 other languages. Files with unreadable, protected, corrupted, or image-only text may not generate usable cards, and AI-created multiple-choice distractors can sometimes be poor.
