We told you about Google Caffeine when it was announced. Some people find the results from Caffeine much better while some people don’t find any differences. If you want to check it out for yourself how Google Caffeine is different from Google, I would highly recommend using this tool.
It lets you compare results from Google and Google Caffeine in the same browser window. You can either view them with a horizontal or a vertical split. I tried searching for “India” and found that Google Caffeine gave me 694 Million results in 19 seconds whereas Google gave me 453 Million results in 33 seconds.
The comparison would of course vary depending on the term you are searching for, but overall, it is a nice tool to see what Google Caffeine is all about and if it is really any better than Google.
