Feedback from Real Customers
Here's what our customers say.
“Excellent value and excellent support. It sounds like a real person reading my work back to me. A huge step up from most other commercially available readers that I've tried.”
“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.”
“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.”
“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.”
“It's a very useful tool with great design!”
“This is an excellent plugin. It can help me read articles on the page with just a click. It can also highlight and scroll through the content. Kudos to the developers!”
“i've been using this chrome extension for quite some time now and i think it's the best thing ever! i use it mostly for school, such as listening to long articles or reading information online.”
“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.”
“I find it to be a great tool as I go through my MBA reading material. Their natural voices and highlighted words make my reading experience smoother than any other tool out there.”
“I did really like the smoothness with which the AI voices could read articles, compared to other tools. The voices don't seem as robotic, making it easier to focus on the text.”
