Here is an example for searching for “cats” with academic turned on. It’s not just .edus but it’s definitely part of the weighting. Nature is usually the first hit obviously.
You can also make custom searches with parameters and link easy access third party buttons. I did one for Google shopping for instance.
I can customise it to ignore AI spam with custom filters + academic search + custom rankings + other custom tools. I can yeet domains from ever being seen again. It’s just very tailored to whatever you need. I hardly go elsewhere now. I find it curbs my compulsive rumination googling because I get clear, trustworthy answers and not AI telling me I have cancer or am distracted by something dramatic.
