I'd love to have a tool to pipe into that removes low-entropy content automatically, perhaps with machine learning.

For example, last week I was grepping through some security logs looking for anomalous logins. There were a bunch of other security events in the log file. Eventually my command looked like `cat /var/log/auth.log | grep -v Disconnected | grep -v cron:session | grep -v 'Invalid user'` and so forth until I only had the "interesting" lines left.

Maybe the right approach to this tool would be to put the lines into a tree based on the longest substrings.
