Unfortunately, the Sifter service and website has been decommissioned as of September 30, 2018. Thanks to our 6,970 users who created 16,128 free estimates from the complete, undeleted history of Twitter between 1/14/2014 and 9/29/2018.
Please contact Twitter for approval of future academic or commercial use cases. If you can get an approved use case from Twitter, we can still help you work with the data inside DiscoverText.
@DiscoverText remains open and is still the top-ranked text analysis platform on the Internet.
All paid jobs prior to the decommissioning will still be honored.
I am attempting to find old (historical) Twitter tweets but Sifter either doesn’t find any or gives an error message. I also cannot find older tweets when using the geo: rule. Why?
The very first Twitter tweet was on March 21, 2006, therefore the start date for any Sifter query must be 03/21/2006 or later. An attempt to enter a start date prior to 03/21/2006 is invalid and will result in an error.
Twitter’s geo: rule enhancements first became available on 08/01/2013. An attempt to enter a start date before 08/01/2006 will likely not return any data for the time period before then.
