ReadAnything: Offline Text to Speech TTS PDF Reader

ReadAnything is a private, lightning-fast on-device text-to-speech reader that turns any web article, PDF document, or EPUB book into natural audio with karaoke-style word highlighting. Powered by modern on-device neural synthesis (WebAssembly & ONNX), your reading material never leaves your computer. No cloud audio streaming, no monthly API subscriptions, and 100% offline functionality after installation. KEY HIGHLIGHTS: • 100% Local & Private: Speech synthesis runs locally in your browser using ONNX WebAssembly. Your documents and articles are never uploaded to any remote server. • Live Word & Sentence Tracking: Follow along visually with karaoke-style text highlighting synced to spoken speech. • Web Article Reader: Automatically strips clutter, sidebars, and ads to deliver clean, distraction-free reading of any news article or blog post. • Dedicated PDF Reader: Built-in PDF reader with page-by-page tracking, dark/sepia themes, and on-device OCR for scanned documents. • Dedicated EPUB Book Reader: Full Table of Contents navigation, chapter pagination, and adjustable typography (Inter, Serif, Outfit). • Floating Desktop Player: Compact mini-player with drag-and-drop placement, speed adjustment (0.5x to 3.0x), and background tab audio playback. • Natural Voices: Choose from expressive neural voices with natural breathing pauses and cadence. • Offline MP3 Export: Save synthesized audio directly as MP3 files to your device for listening on your phone or on the go. HOW TO USE READANYTHING: 1. Web Articles: Open any article and click the ReadAnything icon in your toolbar, or press Alt+R (Command+Shift+U on Mac). 2.

All text normalization, OCR recognition, and audio synthesis happen locally on your device hardware. We do not track your reading habits, do not collect personal data, and do not sell information to third parties.
