Really useful, the popup window is instantaneous and offers a wealth of suggestions. Highly recommended.

Really helpful . Works as expected and lighting fast

i would've liked to use this more but it doesn't work on most of the writing sites i frequent, like asianfanfics or tumblr. though i'm happy to say it works on wattpad and archive of our own. :) just sad that it doesn't work on my other favorite platforms.

Definitely underrated, it would be handy if it had a right click ability so that its easier to get straight to the dictionary.

So far so good! It only works on editable text fields (by default) - but this can be changed. Works as advertised and is OPEN SOURCE!! (All the other thesaurus extensions... who knows what they do in the background??)
