Pourquoi choisir CastReader plutôt que Immersive Reader
Microsoft's built-in reading tool in Edge, Word, OneNote, and Teams ? Voici ce que CastReader fait différemment.
Chrome Support
TTS in Your Favorite Browser
Immersive Reader is built into Edge, Word, OneNote, and Teams — but not Chrome. If Chrome is your browser, CastReader gives you the same core experience: read-aloud with text highlighting. Install the extension and it works on every website.
Any Website
Not Limited to Microsoft Apps
Immersive Reader only works in Microsoft products. CastReader works on any website — Medium, Substack, ChatGPT, Google Docs, Wikipedia, Reddit, and more. Plus it has 15+ specialized extractors that understand each site's layout.
Kindle & AI
Works Where No Reader Does
CastReader reads Kindle Cloud Reader (OCR), WeRead, and adds per-response Listen buttons on ChatGPT, Claude, and Gemini. Immersive Reader doesn't work on any of these platforms.
