This is a small tool that runs some text (paste in textarea below) through some Python code using the emoji package and NLTK collocations (at the moment). It generates CSV-type outputs for emoji and bigram/collocation statistics, as well as "demojized" text, where emojis are replaced with their aliases: e.g. 👍 becomes ::thumbs_up::

There is a desktop version of this app, which should have much better performance. (MacOS / Windows / Linux / github)

v0.2: 1 Jun 2019 (update emoji package to 0.5.2 and adding the ability to deal with two-character emojis)
v0.1: 25 Mar 2018 (release)
