Ember

Ember transforms how you read. Upload a book, and Ember's AI processes it so you can have real conversations about the content, chat with characters as if they were real, and explore visual knowledge maps of every concept. Whether you're a student breaking down a textbook, a professional extracting insights from industry reports, or a curious reader who wants to go deeper — Ember meets you where you are. WHAT YOU CAN DO • AI Chat — Ask questions about any book in your library. Get answers grounded in the actual text, not generic summaries. Select multiple books to cross-reference ideas. • Character Chat — Have conversations with characters from your books. Talk to Sherlock Holmes, Sun Tzu, Marcus Aurelius, or characters from anything you upload. • Knowledge Map — See the key concepts from any book laid out as an interactive visual graph. Tap nodes to explore connections between ideas. • Upload Anything — Import EPUB, PDF, MOBI, TXT, or DOCX files up to 50 MB. Paste a YouTube URL to import video transcripts. Import research papers directly from arXiv. • Public Library — Browse and read free public domain classics from Project Gutenberg. Aesop's Fables, The Art of War, Meditations, On the Origin of Species, and Sherlock Holmes are ready to explore immediately. • Collections — Organize your library into collections. Filter by collection when using Transform features. • Personalized Experience — Choose your archetype (student, professional, personal growth, homeschooler, or curious explorer) and Ember adapts to how you learn. BUILT FOR READERS Ember isn't another reading app. It doesn't just display text. It understands what you're reading and gives you tools to think with it. Every AI feature is grounded in the actual content of your books — no hallucinated answers, no generic responses. Your books are processed securely and stored in your personal library. Delete your account and everything goes with it. From Alchemaize, Inc. — we build apps that solve daily problems.
