Goodbot is a chatbot that sends welcome messages to newly joined participants and helps answer some questions about the different outreach programs like Google Summer of Code, Outreachy and Season of Docs. You can chat with it on any Wikimedia Zulip stream.
Ircbot bridges all communication between the #technical-support<https://wikimedia.zulipchat.com/#streams/technical-support> stream on Zulip and the IRC channel #wikimedia-tech. It allows the participant community on Zulip to interact with the broader Wikimedia community that is primarily active on IRC. You can see ircbot active in both the aforementioned channels.
