“Overall this extension is great, the voices are just right and read out loud well. This has helped me tremendously with my course load. I learn more by listening than by reading so this was perfect.”

Sandra

“Great extension! It's easy to use, the voices sound natural, and the narration is smooth and easy to follow. This is the best AI text-to-speech extension I've come across.”

Tomer

“Really good tool! I've used a few different 'AI Readers' and this is by far the best. Highlighting the text that it's reading currently is a great edition. The voice is very human like.”

“This extension is exactly what I needed. What really impressed me was its ability to read both original English content and translated pages in other languages with natural-sounding voices.”

“Amazing extension, sounds a lot better than Speechify. Still a little buggy, which I believe will be fixed in the future.”
