Atlas AI turns anything you read or learn into something you can actually remember—fast. Paste a link, open a PDF, snap a photo, or type your own text. In seconds, Atlas AI creates summaries and full test banks with flashcards and quizzes so you can study both knowledge and languages with less effort. Why Atlas AI? Reading is slow. Remembering is hard. Manually making flashcards and quizzes takes forever. Atlas automates the busywork—source → summary → flashcards → quizzes—so you can focus on understanding and recall. What you can do Knowledge mode (articles, textbooks, research) • Deep Search: Paste text or a URL to analyze articles, docs, research papers, or web pages. • Scan & OCR: Photograph pages/handouts; Atlas extracts the text with high accuracy. • Smart Summaries: Adjustable depth (brief, standard, detailed) with clear key takeaways. • Test Bank Generator: Create mixed practice from any source—flashcards, multiple-choice quizzes, true/false, match, and short-answer write questions. • PDF Tools: Import PDFs from Files or the Share Sheet and convert them into summaries, flashcards, and quizzes. Languages mode (vocabulary & grammar) • Turn any text, PDF, or web page into vocabulary lists and drills. • Auto Flashcards: Generate focused cards with translations, definitions, and example usage. • Quiz Modes: Practice with multiple choice, type-the-answer, true/false, and matching pairs. • Two-way practice: Study from native → target language and back again to lock in new words. Shared tools • Organize & Sync: Save sources to folders, mark favorites, and quickly revisit your study sets. • Edit & refine: Tweak summaries, edit questions, and customize flashcards. • Dark Mode: Easy on the eyes for late-night study sessions. How it works Choose your mode – Knowledge or Languages. Add a source – paste text/URL, open a PDF, or snap a photo. Pick what you need – Summary, Flashcards, Quizzes, or a full test bank. Review & refine – Edit points, merge/split cards, and export or share. Who it’s for Students, language learners, researchers, journalists, and knowledge workers—anyone who reads a lot, studies new material, or needs to retain important information.
