Not free—unless your time spent making it work is worth $0. Pros: + Opens a small over-the-page window for quick word lookup Cons: - The treasure is limited, so it doesn't find or define all words - Made by developers for developers. Hear me out: After a while, it stopped working, saying I needed to put in an "API key," with no further information provided. So, I went searching. Perplexity instructed me to create an account on their developer website (https://dictionaryapi.com/), but the website directed me to start with the "products" page. The products page didn't seem to include anything related to extension APIs, so I clicked on a strangely located "register" link to follow Perplexity's solution. I closed the registration page the moment I saw the form! It fails basic UX and accessibility standards, and it's ridiculously long, with fields that aren't relevant for consumers or single users. I felt so cheated because when you factor in the time spent getting this extension to work, it actually makes it very expensive and NOT FREE.
easy to use
Fast & clear to find my answer.
so good
Seems like an odd thing to say, but for a dictionary, this application has all the bells and whistles. I feel more secure with it since I registered and got my FREE key to proceed after 20 uses.
Amazing I am and English Lit Student and this works amazing
Absolutely love it!!! after signing up, the 20 word limit was lifted. absolutely love the quickness of definition calls. Almost instantaneous. SUGGESTIONS: 1 - Would be amazing if I had the option to make the pop-out box bigger...its a struggle to read everything in the current tiny pop-out box. 2 - I saw another user suggesting to make the pop out box come out on the top right of the page where the extension would be...I definitely second it. it would be much better and wont block your content like it does now on the middle of the page.
When I highlight a word, I would like the option of the definition automatically popping up in the extension at the top right rather than on the page.
