An amazing dictionary tool. Quite literally the best I've ever used. It doesn't just look up words, it can be used to look up entire phrases and slang terms. And setting up hotkeys makes this tool super easy and convenient to use. I don't know what I ever did without this!
I really like the extension and have been using it for almost a year I think. But recently google search option has been giving me the "I'm not a robot" checkbox page and it never goes away even when I check the checkbox
Отличное расширение. А возможно ли добавить опцию передачи cookie в сплывающее окно? Было бы удобно быть залогиненным на сайте, где смотришь определение слов.
it's very good extension . it has fast search . you should be get it
Can't make double tap to define feature for PDFs. yeah, I gave it permission for url files. hopping for you to look into it Otherwise, an excellent extension.
Absolutely delighted to use this, it's well made, and is certainly better than the defaults! I like the onboarding, also, an extension where the usage and features are so well described!
I'm really impressed with how well this extension works.
This extension is a god send! I was getting really annoyed with Google's Dictionary so much so that I planned on making an extension myself, lol. After being frustrated enough from Google Dictionary extension, I came across Definer. This is what I wanted and more.
Absolutely amazing and incredibly useful for a multitude of workflow relief. God, I love this extension! I want to reiterate the words of the other reviewers here and acknowledge the creators effort to make this app as high quality as it is. Magnificent work and this is now a solidified part of my workflow and keeps me on task effectively. Thank you for this amazing extension and I wish you even more success!
Ещё одно расширение скатилось в нейротерроризм. Крайне обидно.
