A month ago, Microsoft started testing a new search feature named Bing Saves. This feature enabled searchers to save URLs and searches to their personal Bing/Microsoft account, in order to build an index of their own saved searches.
That feature seems to now be available as public beta for anyone who wants to try it. To try it yourself, go to bing.com/saves and you should see this dashboard:
You will also see a link in the top Bing navigation that says “SAVES beta.”
There is a disclaimer on the footer of the page that reads, “This feature is an experiment. Saved results may not be available later.”
