Unfortunately, there is no discounted price on Gnip PowerTrack credits. The prices for DiscoverText software licenses are reduced by 50% for academic faculty and 75% for students.
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.
