EasyReader vs Readholic

Read Epubs and PDFs with the help of AI. Just circle something to get an AI explanation! EasyReader makes it easy to understand textbooks full of math and diagrams. It leverages vision large language models to understand and explain anything you circle.

Read difficult material without breaking your reading flow. Readholic is a PDF and EPUB reader built to help you understand and retain what you read — textbooks, research papers, technical books, classics. When a passage is unclear, select it and tap Explain. Ask follow-up questions, turn the same material into flashcards or quizzes, and review it with spaced repetition until it sticks. NEW IN 1.1 • Your own AI key: a one-time purchase lets you use your own API key from OpenAI, Anthropic, Google Gemini (where available) or DeepSeek for AI explanations, follow-ups and flashcards. No AI service is included; your provider bills you for its use. Your key is stored only on your device, and these requests don't count toward Readholic's plan limits (fair-use limits apply). • Nine reading themes: White, Linen, Sepia, Sage, Mist, Contrast, Dusk, Dark and Midnight. Figures and images adapt to the theme. • New reading fonts: Literata, EB Garamond, IM Fell English, Atkinson Hyperlegible Next, Lexend and OpenDyslexic. OpenDyslexic and Atkinson Hyperlegible Next can help readers with dyslexia or low vision. • Choose the highlight color that marks the passages AI has explained for you. • A redesigned AI Explanation sheet with a cleaner, margin-note look. READ AND UNDERSTAND • Read your PDF and EPUB books and documents in one place. • Select a difficult passage and get an AI explanation without leaving the page. • Ask follow-up questions while the original text stays in front of you. • Every explanation is saved with its highlight, right where you found it. • Works with real academic material, including mathematical notation. FIND SOMETHING TO READ • Import your own files, or download public-domain classics from Project Gutenberg. • Get free open textbooks from OpenStax, converted for comfortable reading. • Read research papers from arXiv as clean, reflowable text. TURN READING INTO STUDY • Generate flashcards from a selected passage or a whole chapter. • Quiz yourself with multiple choice, fill-in-the-blank, and written answers graded by AI. • Review with spaced repetition — due cards wait for you in the Study tab. LEARNING MEMORY Readholic keeps a short summary of the concepts you have studied so future explanations can build on what you already know instead of starting from zero. You stay in control: view, disable, or reset it in Settings at any time. LEARN WITH THE COMMUNITY • Discover flashcard decks shared by other learners. • Search by book, subject, or topic, and filter by language. • Download decks to study in Readholic, rate the useful ones, and thank their creators. • Share your own decks. Only the cards you publish become public — never your books, notes, or reading history. YOUR LANGUAGE, YOUR CHOICE • The app speaks English, Spanish, French, German, Portuguese, Chinese (Simplified and Traditional), Japanese, Korean, and Arabic. • Choose the language of explanations and flashcards independently of the book: read an English textbook, learn in Spanish, Japanese, or Arabic. Readholic is for students, professionals, researchers, and lifelong learners who want more than summaries. Read → Explain → Understand → Flashcards → Quiz → Review → Remember You can start free. Some AI and study features require Readholic Pro (auto-renewing subscription). Using your own AI key requires a separate one-time purchase.
