What is the difference between historical tweets via Sifter and Gnip PowerTrack livefeed?



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.


There are two ways to acquire Twitter tweet data – historical and live “Firehose” feeds.

Historical Tweets via Sifter

Using Sifter you can search through the entire undeleted history of Twitter data from the inception of Twitter until the current time.

Our pricing model is simple:

  • Three free estimates per day.
  • $25 per day of data retrieval.
  • $7.50 per 10,000 tweets.
  • Any Sifter purchase includes 14 days of Enterprise DiscoverText access. This enables up to three users to collaborate on the dataset.
  • Realtime Gnip Twitter collection via DiscoverText avoids the $25/historical day charge on Sifter.

The cost includes licensing the data from Twitter plus a $25/day fee while using the service. Please see http://sifter.texifter.com/Home/Pricing for more information.

Gnip PowerTrack Livefeed

Twitter data can be collected more affordably using the real-time Gnip PowerTrack Twitter feed in DiscoverText, which is a day-forward version of the data stream from the time you start the data collection. This is also known as the "Firehose." Data begins to arrive as soon as you set up the data feed, and stops when you pause or delete the data feed.

The cost includes the cost of licensing the data from Twitter; there is no per-day fee.
