About this app
TextStack is a free reader for real books. Upload your own EPUB or PDF, or open a free classic, and read in a clean, distraction-free reader with help exactly where you need it.
KEY FEATURES
• Read anything — upload EPUB/PDF or open free public-domain books.
• Tap to understand — press and hold any word for an instant translation and a clear, in-context explanation.
• Use your own AI assistant — connect Claude, ChatGPT or another assistant to your library, discuss what you read, and save insights, highlights and vocabulary back into the book.
• Listen as you read — natural text-to-speech in 200+ voices, with adjustable speed.
• Build vocabulary that sticks — save words while you read and review them with spaced repetition (SRS).
• Highlights & notes — mark passages and revisit them later.
• Track your progress — reading stats, streaks, goals, and achievements.
• Offline-first — download books and read anywhere.
