Google translate suddenly stopped working unless I use a vpn. I searched on reddit for solutions to this problem, and configutrd DeepL as my custom source for translation but it looks ugly. I hope th edeveloper fixes this issue soon
PLEAAAAASE add wordreference as a source. I am not allowed to use translators for my spanish class (only dictionaries), so I have to have google translator off and only use the google dictionary, but the google dictionary doesn't work well for spanish. Having wordreference as an option would provide a full spanish dictionary without having to turn google translator on.
very helpful and perfectly made
Subject: Feature Request: Back Button Navigation Please add a "Back" button to the definition popup. When I click on a new word or synonym inside the window, there is no easy way to return to the previous word. Adding a back arrow or supporting the "Backspace" key would make navigation much better.
Sehr gute Erweiterung. Endlich habe ich die Möglichkeit Wörter nachzuschlagen, ohne einen neuen Tab öffnen zu müssen, welcher mich wieder ablenken würde. Durch "AI Translator" kann ich meinen Fokus auf der aktuellen Seite behalten. Beim Google Translator habe ich das Problem, dass englische Wörter eins-zu-eins übersetzt werden, ohne ein Synonym bereitzustellen, z.B. Diaphragm wird zu Diaphragma übersetzt - wenn ich jetzt nicht wüsste, was Diaphragma bedeutet, müsste ich doch wieder einen neuen Tab öffnen. Dieses Problem habe ich nun nicht mehr, da ich per weiteren Klick die Google-Suche im Popup-Fenster befragen kann und weiter auf der aktuellen Seite bleiben kann. Außerdem ist die Einbindung von YouGlish genial! - Kannte ich davor gar nicht. Ich bin hoch zufrieden. Vielen lieben Dank!!!!
Really appreciate this wonderful effort, it's really helped me a lot, thank a lot to all the team members.
I use this every time I want to learn English or Japanese; as I explore the web, I can look up the meaning and have it directly translated into my native language, eliminating the language barrier. Easy-to-use UI with the ability to add custom sources. In the future, please include DeepL as a source because their translation is excellent. Anyway, it's a very useful and user-friendly software. Thank you so much for creating this extension.
I have to login to vote. Amazing extension
Genuinely impressive with the number of useful features, customization, and feel. No other dictionary extension comes close.
Useful.
