Taggrbot

Taggrbot is a cloud service added as a plugin to enterprise messaging platforms like Slack. Taggrbot will automatically tag your messages with concepts, index them, and then allow you to search those tags.

For example, you posted "WaterIsLife in Johannesburg is having delivery issues again. Connect with @Jen and find out what's wrong." In your Slack channel, Taggrbot tags it "Question, Problem, South Africa, Nonprofit, Colleague." Later, you can search for those tags in Slack. Now you can find that one message you vaguely remember in the hundreds you've posted. Making search better.
