SecondBrain is a transparent prompt optimizer built specifically for everyday AI users. We clarify your intent, tighten your wording, and show you exactly what changed. Once you secure the perfect result, you can instantly build a library of repeatable requests.

Try it with the next prompt you were about to rewrite manually.

Very well. If possible, could you allow the option to **remove or hide icons on websites**? They're quite annoying.

This is a wrapper of gemini.google.com. We can already use gemni.google.com inside of Chrome in many places and many ways. For example, just enter your message to Gemini.google.com in search and URL bar with @ mark like "@this extension is a wrapper UI?" Furthermore, Google has already released "The Official Gemini GUI Functions for Chrome" now in English. This Gemini is Chrome's functions and GUI, not a just wrapper. In this system, Gemini is deeply integrated inside of Chrome to work mainly locally as one software. I recommend to try out the early Chrome build such as Canary, Dev, Beta for the fastest access of the usage not only in English. BTW, Chrome already includes Gemini Nano in Dev mode and General Usage who get it while the trial period.

There's a huge disconnect between what we see in the news / media regarding AI, and the reality. Or, the versions of the services we're getting are being massively restricted. How can it be true that everyone should fear for their jobs, yet Gemini can't move emails to a folder based on the content... As for not being able to see content of the page, it makes it completely irrelevant as an extension. It's a bit like getting an extension on your house that isn't attached to your house. Then there's the inability to retain information about previous conversations or the user. Google probably know how many times a day I drink tea, but the service they're selling me can't remember what I asked it 10 minutes ago? We're being sold a lemon, and it's by design.

Pretty nice to have a quick and easy way of accessing Gemini. Only wished there was an option for the sidebar to remember where you left of instead of always starting a new thread when you reopen the sidebar.

No lo he probado mucho pero parece cumplir con lo que dice aunque siento que no es tan inteligente como en la página oficial.
