Mythos Reader
Mythos Reader is an AI book reader application for iPhone and iPad, designed to remove friction when readers encounter passages they do not fully understand. After a user uploads an EPUB or PDF and highlights text, Mythos analyzes the selected passage to infer what question the reader is likely to ask. It then presents suggested actions such as Explain, Define, Summarize, or Who is this character? directly next to the text, eliminating the need to type a prompt or switch apps. The app's core idea is that readers often want to ask a question but do not want to formulate it from scratch, so Mythos provides the question for them. The app adapts its suggestions to the nature of the content. Highlighting a character name may prompt an introduction, a dense paragraph may lead to a simplification, and an unfamiliar term may trigger a context-specific definition. Readers can still type their own questions and follow-up queries, but they never have to begin from an empty prompt box. This contextual intelligence is designed to work across different genres and formats, from literary fiction to technical PDFs, making the reading experience more continuous and understandable. Mythos emphasizes a calm, book-like reading environment with AI tools that appear only when selected. It supports EPUB and PDF formats and is available free to download from the App Store with a 4.9 rating. The app does not include a built-in bookstore; instead it focuses on letting users read their own uploaded documents while offering AI assistance exactly where and when confusion occurs.

Problem solved
Readers often lose momentum or comprehension when they meet a name, term, or dense argument they do not understand. Mythos Reader solves this by letting users highlight any passage, after which the AI infers the likely question and instantly offers an answer or explanation within the reading interface, so readers can continue without writing prompts or leaving the book.
