Esta genial la recomiendo a todos
When using the Arc browser with a specific extension enabled, I’m unable to sign in to platform.openai.com via Google. I get the following message: “We ran into an issue while authenticating you. If this issue persists, please contact us through our help center at https://help.openai.com.” Disabling the extension resolves the issue. Might be worth looking into compatibility.
It's working perfectly. The only issue I have is that when I open the Google search window, Google's AI Overview option appears for a split-second, before disappearing from the I-frame. This happens to me in Brave browser. Please fix this, because this extension is otherwise very useful.

Wow! Очень круто! Просто замечательная программа, спасибо большое разработчикам!
Получилось встроить как настраиваемый источник лучший в паре переводчик ru-en https://translate.yandex.ru/?utm_source=main_stripe_big&source_lang=en&target_lang=ru&text=/{{str}}
alot more useful than google dictionary
Awesome extension! It's comprehensive and significantly improves my reading experience and access to non-native language materials. It would be even better with vocabulary.com and etymonline as sources.
Such a fantastic extension! Very smooth, very concise and clean, and exactly functioning as a dictionary and translator. I wish I can pay for it! But it only accept cryptocurrency, which I don't have. That is the only downside!
Awesome app. Can you provide option for 11labs tts api with our .own key
