I hate reading long articles/documents and 90% of the time, I absorb much better by listening.

Recently Supertone, Inc released an ultra lightweight opensource Text-To-Speech model with natural voices (not the robot sounding crap).

I was pretty intrigued by it and used it to build a Chrome(-based) browser extension that reads web pages and PDFs aloud for my own personal use.

What’s so unique about it?

  1. Privacy-focused: Everything happens on your computer, nothing goes to the cloud.
  2. Lightweight & fast: It works on most modern computers without needing a graphics card.

As with most of my hobby projects, this extension is open source and free for use. It’s in a state of what I would coin as early development but good enough for casual daily use with pending bug fixes and enhancements. If any of you happen to be interested to give it a try, you can find it here.

For those of you who are technical and curious, you can find the source code at:

Perhaps what’s notable is that AI (Claude) did most of the coding. 🤓

This sort of concludes my, for various reasons, a much shorter annual Christmas hacking session this year which I started a little early even before the holidays began.

Hope everyone is having a wonderful holiday season! 🙂
