Since Twitch's chat is based off of IRC, in theory this should be somewhat simple.

There would be a section in the Twitch dashboard under moderation where you could go and view the chat logs either for individual streams, or for certain dates, or use wildcards/keywords/filters/tags to find what you are looking for.

This would help with moderating your chat, and make sure people were not abusing others while you're offline or away.

I've heard that posting Twitch chat logs is against TOS or something, so you would have to outline restrictions and rules in the TOS and community guidelines when applicable, or perhaps make it that Twitch chat is public and anything you post can be posted elsewhere, etc.

The current solutions for this are running an IRC client or Twitch chat client and logging everything to a text file with no real search functionality, so you just end up reading for hours just to make sure one person didn't curse too many times or whatever. Bots have tried to do it, but rate limiting and lack of functionality have often kind of made that also not an elegant or practical solution.

I also could have sworn this was even announced as a feature that was already coming, but I saw no mention of it anywhere else so I thought I'd bring it up.

Lemme know your thoughts, feedback, etc.

Thanks for reading, happy streaming.
