Co-founder of MetaChat here. We’re NLP nerds who have been playing with the Slack API for a while. Lots of people complain about notification overload (e.g. Wednesday's article in The Verge[0]), so we’ve been trying to tackle that with search and summarization.

Feedback welcome! For instance I think the search works quite well for my Slack teams, but maybe you use unusual words that trip up our code and make the results less useful.
