Point it at your policies, runbooks, and wiki exports. Your team asks in Slack — by DM or @mention — and gets a sourced answer in seconds instead of pinging a colleague.
The highest-volume questions in most companies are internal: "what's the VPN setup?", "how many PTO days roll over?", "where's the expense policy?". Upload those documents to an agent, connect Slack, and the answers meet people where they already ask — without a ticket, and without interrupting whoever maintains the wiki.
If a question needs a person, the conversation escalates like any other channel: the AI mutes, your workspace admins are notified, and a teammate's dashboard reply reaches the asker as a direct message from the bot.
You create a small Slack app in your own workspace (about two minutes), give it a bot token, and paste the token plus signing secret into the dashboard. Chat Cactus validates the token immediately. Because the app is yours, you control its name, icon, and permissions.
In two situations: when someone DMs the bot, and when someone @mentions it in a channel. It deliberately does not read or answer every channel message — no noise, no surprise interjections.
Channel @mentions are answered in a thread on the mentioning message, keeping channels tidy. DMs are answered inline.
The documents you upload to the agent — your internal wiki exports, policy PDFs, runbooks. Answers use Slack’s own formatting, and the same agent can simultaneously serve your website widget or email.
Every event from Slack is checked against your app’s signing secret with a replay-window guard before it is processed, and the bot ignores its own messages so it can never loop.
