First impression: Far too slow to replace Google Search for this use. I frequently get 5+ seconds of waiting before the first word of a response shows up, vs. less than 1 for Google (which is not as fast as it used to be). OpenAI has a lot of work to do on latency.
I can definitely see this new search feature being useful though. The old one was already useful because (if you asked) you could have it visit each result and pull some data out for you and integrate it all together, faster than you could do the same manually.
It's often hobbled by robots.txt forbidding it to visit pages, though. What I really want is for it to use my browser to visit the pages instead of doing it server side, so it can use my logged-in accounts and ignore robots.txt.
I tried hacking this together a month ago as an experiment and it was super painful. This seems like exactly what I wanted - props to OpenAI. Google should be on DEFCON 2.
How did you find the extension? Searching the Chrome Web Store for 'SearchGPT' turns up a ton of third-party extensions, not made by OpenAI. Also, there doesn't appear to be a way to search by developer.
If you don't like that (like I do), you can also manually add it under Site Search using
