Viewer Ebook

Purpose-built ebook viewer and analyzer that processes EPUB and PDF files for local viewing and study workflows. It extracts text, builds a navigation structure, and computes reading metrics without altering content. Conceptually, the tool treats each document as a structured data source: pages, headings, and highlights are mapped to a consistent internal model to enable fast navigation and analytics. This yields tangible value for students, researchers, and professionals who need quick access to reading progress, word counts, and exportable notes. Unique differentiators include offline operation, emphasis on exportable annotations, and a privacy-first design that avoids remote processing. Core features encompass format support, TOC parsing, bookmarking, search, annotation export, and reading-time estimation. Use cases include study sessions, article review, and content curation for classroom materials. Advanced capabilities enable multi-device sync and structured exports for note-taking workflows, without requiring a full editor or cloud dependency. Benefits include improved study efficiency, clearer reading plans, and reusable highlights for revision. The tool focuses on domain logic rather than UI, so data structures, parsing pipelines, and deterministic metrics are central. Ideal users are students, teachers, researchers, and lifelong readers who value measurable reading progress and portable notes across devices.
