Le microphone ne fonctionne pas depuis l'extension, alors qu'il fonctionne sur le site visité depuis le navigateur
Good but it lacks some features that would greatly improve the use, for example: - the ability to hide the side icon from the screen, the one that opens gemini on the sidebar; - the ability to open gemini by highlighting text on a web page, right click, open gemini and copy the text directly to the gemini text editor without having to retype or copy and paste; - the ability to open gemini and use it when using the browser as a pdf reader;
Can you please give the ability to remove that annoying floating button that shows up on every website. Why can't Google make their own extension for Gemini?
microphone is not working with this addon -- tried all possible options ...
The extension works great but the little shortcut on the bottom right of the screen appeard when I print a paper. Like exporting a pdf from google sheet, the little round shortcut appear on the printed pdf haha weird stuff I don't know if we can remove it ?
I liked the extension, but I just removed it as i got a waring from my chrome browser thatit violated the Chrome Web Store policy.

what is the use of it if it cannot "see" the web page? me: summarise it extension: Please provide me with the text you would like me to summarize. I need the content to be able to help you. me: summarise this page extension: It's important to understand that "summarizing a page" can refer to a couple of different things, especially with the rise of AI: Summarizing web content using AI tools: Many AI tools and browser extensions are now available to generate concise summaries of web pages. These tools analyze the text on a page and extract the key points. These tools are designed to save time by providing quick .....
this extension is really good, served its purpose and did well anyone who said it is bad is foolish
Está buena, es práctica, sin embargo no sé si es solamente en mi caso pero inclusive después de corroborar los permisos, no puedo utilizar el micrófono para escribir mediante dictado. Le agregaría a futuro la función de poder seleccionar algún ítem desde el buscador y de la misma forma que aparece el botón de open Gemini, que aparezca un botón de consultar con Gemini y que automáticamente se vuelque al chat
