Privacy Policy
Readalix runs entirely in your browser. It never sends the pages you read, your text selections, or any personal data to a server, and there are no accounts, tracking, or analytics. Speech is produced by your browser's built-in voices or, optionally, by neural voices that run on your device; those optional voices download open-source model files directly from their public hosts and cache them locally. The extension requests only the browser permissions it needs to read the current page aloud on your command.
Frequently asked questions
What is Readalix?
Readalix is a text-to-speech (TTS) Chrome extension that reads any webpage aloud with synchronized word-by-word and sentence highlighting, so you can read along by ear and eye at the same time.
Is Readalix private? Does my text get sent to a server?
Yes, it is completely private. Readalix runs entirely on your device. Your selected text and the pages you read are never sent to any server, cloud, or API. There are no accounts, no tracking, and no analytics. Speech is generated by your browser's built-in voices or by optional neural voices that run on-device.
Can it read PDFs, Google Docs, and Word documents aloud?
Yes. Readalix reads PDFs in Chrome's built-in viewer (including scanned, OCR'd PDFs), Google Docs (canvas-rendered text), Google Slides, Microsoft Word Online, and PowerPoint for the web — as well as ordinary web pages, form fields, text inside Shadow DOM web components, and embedded iframes.
Does Readalix work offline and without the cloud?
The built-in browser voices and the optional on-device Piper and Kokoro neural voices synthesize speech locally with no cloud. Voice model files download once from their open-source hosts and are then cached, so reading works without sending your content anywhere.
How many languages does it support?
Readalix reads and highlights in dozens of languages using your browser's voices, plus high-quality on-device neural voices. Languages are listed by their native names, and the voice is remembered per language.
