Winda

About the startup

Read with a purpose Winda is a reader that turns what you are studying into questions and schedules the review. Bring a PDF, web article, YouTube video, presentation, image, Word document, or text snippet. Winda gives you a focused reading space with AI beside the original material, so you can ask questions, annotate passages, and clarify difficult ideas while you read. From reading to active recall Winda creates editable flashcards and quizes from your own material. Each question stays connected to its source, making it easy to check the original context instead of studying isolated AI-generated answers. Once a question joins your reviews, Winda schedules it with spaced repetition. Answer correctly and the interval grows. Miss it and the question returns sooner. What you can do with Winda - Import PDFs, articles, YouTube videos, slides, images, and documents - Read the original material with an AI assistant beside you - Generate editable flashcards and quiz questions - Return from a question to its original source - Review with built-in spaced repetition - Save web pages through the Chrome extension - Organize material into decks - Share selected decks publicly How Winda is different AI notebook tools help users ask questions about their sources, but often replace the original with summaries and chat responses. Winda keeps the original material at the center of the experience. Traditional flashcard apps provide reliable review scheduling but leave users to write every card manually. Winda drafts the questions while the user reads, keeps the source attached, and schedules the review in the same workflow. Winda is free to start with no credit card required. Reading and reviewing never consume AI credits.
