Hi! Thanks for volunteering to test :)

I'm a solo-developer and I've been testing Artiful on my Boox Palma and Note Air devices.

Here are the two steps to install it:

1. Install Quetta, it's one of the few apps that supports running Chrome Extensions - https://play.google.com/store/apps/details?id=net.quetta.browser
2. Install Artiful from the Chrome Extension Store - https://chromewebstore.google.com/detail/artiful-text-to-speech-re/ihpbighnbdibbdogddcaaocmboggmdgm

This also means you can try the TTS from your computer web browser!
