Privacy First

The ultimate EPUB web reader

Fast, private, and local-first. Experience a reading environment that respects your library and your data.

Why most online EPUB readers fail

Traditional online document readers require you to upload your personal files to their servers.

This introduces major issues: your personal library and reading habits are stored on third-party servers, you have to wait for large files to upload, and if you lose your internet connection, you lose access to your books.

The Visus advantage

100% Private

Parsing happens locally. We do not have servers that store your EPUB files or track what you read.

Works Offline

Once loaded, your book stays in your browser cache. Disconnect from the web and keep reading anywhere.

Multi-format

Beyond EPUB, Visus supports PDF and raw text files with perfect, clean formatting extraction.

Integrated speed reading

Built for power users.

Unlike basic EPUB readers that just show you a static page, Visus integrates seamlessly with our RSVP engine and speed reading guide. Toggle between traditional pagination and high-speed RSVP mode instantly.

Our parser supports multiple text encodings and intelligently identifies chapter breaks, providing a navigation experience that rivals dedicated desktop software while running entirely in a browser tab.
