NotePeeker by Adarsh P Thomson

NotePeeker is a lightweight browser extension for viewing Markdown files and local EPUB books directly in your browser.

It provides a clean document-style reading experience with:

• Markdown formatting for headings, lists, tables, code, links, and images
• Offline EPUB reading with chapter navigation
• EPUB stylesheet, image, and font support
• Dark theme, zoom, full-width mode, and printing
• Optional plain Markdown source view
• Offline-only mode for local Markdown files
• GitHub exclusions to avoid replacing GitHub’s native Markdown rendering

NotePeeker does not collect analytics, require an account, or send document contents to external services. Remote EPUB files are left unchanged; EPUB support is limited to local files.
