I asked it to summarize new features from a technology website which its model had out of date knowledge, and it made me a diff of new things available.
I also asked it to be a critic Go code from a pull request that I provided it the URL.
I just provided ChatGPT with a link to your comment and it claimed it was a "a link to an article on TechCrunch about a startup called Tava Health." I gave Bard the same link and it claimed it was a page about a tool called "TLDR This."[1]

edit: After playing with it some more, it's evident that Bard can perform web searches and likely access cached content like Bing Chat.
It may be more accurate than ChatGPT sometimes, if it's using Googles latest web index. The url I used has nothing publicly available and is likely not indexed.
