Communalytic is a new Reddit community analyzer.

It’s a research tool designed to collect, analyze and visualize public data from Reddit.


Collect public posts, replies and metadata from a specific Reddit group.


Conduct 'toxicity' analysis on posts and replies using a machine learning API that assesses the perceived impact a comment might have on a conversation.


Visualize "who replies to whom" signed social networks from your data with each tie storing toxicity-related weights.
