What? Use the form above to query Google Scholar. Start with a simple author query, e.g. alan turing. Results will be processed to compute and visualize the corresponding H index (and other metrics). Note that since Google does not serve more than 1000 results for any query, the output might be partial in some cases...

How? The service is implemented in Python. The latest source code is freely available under the GNU General Public License (GPL), version 2.

Why? This service was created to illustrate how hard it is to compute the "right" index for a particular person. It is not intended as a tool to compute other people's index but rather as a way of understanding - and possibly arguing against - other people's computations of one's index.

Sending automated queries to Google is against its Terms of Service. When they detect multiple queries coming from the same IP address, Google servers usually send an error page that contains a captcha and requires user interaction. This breaks scHolar index from time to time. I would argue that it does not send automated queries as it just forwards your query to Scholar and rearranges the results. Yet, the fact that a lot of people use it probably makes it look like a robot running on our web server.

I might try to find a workaround someday. In the mean time, you can always download the source code (see below) and run it on your own server. Or just create your own profile on Google Scholar now that they provide citation counts.
