  Riddi turns web articles into natural-sounding speech using local AI models that run directly in your browser.
  
  No cloud TTS service. No API keys. No article text sent to a server for speech generation.
  
  Use Riddi when you want to listen instead of read: long articles, documentation, essays, research, tutorials, or any page where your eyes need a break.
  
  What Riddi does:
  
  • Reads clean article text aloud
  Riddi extracts the main content from a page and skips common clutter like navigation, ads, and sidebars.
  
  • Runs locally
  Speech is generated on your device with bundled neural TTS models using ONNX Runtime. WebGPU is used when available, with WebAssembly fallback.
  
  • Supports multilingual reading
  Riddi uses Supertonic 3 with support for 31 languages. It can detect the page language automatically, or you can choose one manually.
  
  • Lets you choose what to read
  Use full-page article playback, or select a specific text block when you only want part of the page.
  
  • Keeps your place visually
  The current paragraph is highlighted while speech plays, with word-level highlighting and smooth scrolling.
  
  • Includes built-in voices
  Choose from 10 bundled voice styles, adjust playback speed, and tune quality steps.
  
  • Stays out of the way
  Use the floating player on the page, or disable it and control playback from the extension popup.
  
  Riddi is built for private, local, distraction-free listening.
