The 3-day free trial comes with one important limit: there are no data exports. There are no exports because the trial is about testing the software and not about getting the data. We want you to experience text analytics and make a decision about whether or not to be a customer.
As part of that experience, we do enable access to the Gnip PowerTrack for Twitter, and also public Twitter via the search API, Facebook pages, as well as other data sources. There are real costs to support our free trials, but we think it makes testing the software more fun.
If you decide that data export is important, we ask that you subscribe to our lowest cost service (Professional) for $99/month (discounted to $49 for academics and $24 for students) for at least one month. Then you can export CSV files of archives and buckets for use in third party software.
Important Note for Twitter Researchers: The Twitter Terms of Service limit users to "save as" CSV no more than 50,000 Tweets per day. When you pull Twitter data in from the Search API, or license it via a Gnip PowerTrack or Sifter, the data is meant to be manipulated and analyzed in DiscoverText, in line with the spirit and intent of the Twitter Terms of Service. Once raw data (in "Archives") has been transformed through search, filtering, clustering, coding, or machine classification, the results (the "Dataset") can be exported at a rate of 50,000 per day.
