AI agents for Slack
A Monmo agent uses Slack the way a well-organised teammate does. It reads the channels you choose and tells you what was decided, drafts updates and answers about work in progress, finds old decisions and asks people for times when a meeting needs arranging. It sees what your own Slack account sees, and every post or message waits for your approval.

What agents do in Slack
Summarise your channels each morning
Each weekday at 8:30 it reads the channels you name since the day before and gives you the decisions, the open questions and the messages that mention you, with a link to each thread.
AskEvery weekday at 8:30, summarise #product and #sales since yesterday: decisions, questions and anything waiting on me.
Post the Friday update
When the week's numbers or shipped work are ready, the agent writes the post for the right channel, short enough to read on a phone, and shows it to you. It goes out when you allow it.
AskEvery Friday at 4, write the week's update for #announcements from the tracker. Show me the post first.
Ask people for meeting times
To arrange a meeting it checks the calendars it can see, then, with your approval, asks each person in Slack which of three slots suits them. It collects the answers and prepares the invitation for the slot that works.
AskAsk Jamie and Priya in Slack which slot works for the pricing review next week, then book the one they both pick.
Answer questions about work in progress
When someone asks in a channel where a piece of work stands, the agent checks the tracker, the document and the latest thread, and prepares a reply with the status, the owner and the link for you to approve.
AskJamie asked in #clients where the Northwind proposal is. Check the tracker and draft a reply with the status and the link.
Find a decision in old threads
Ask what was decided about annual pricing in March. The agent searches the channels your account can see, reads the threads and tells you who decided what, on which date, with links to the messages.
AskWhat did we decide about annual pricing in March? Link the thread and tell me who signed it off.
Turn a long thread into actions
After eighty messages about a launch, it lists the actions, who took each one and by when, and drafts a short recap to post back in the thread so everyone works from the same list.
AskRead the launch thread in #marketing and list every action with an owner and a date.
Catch you up after time away
Back from a week off, you get one page: what was decided, what changed, who is waiting for you, and the five messages to answer first. It reads only the channels and messages your account can open.
AskI'm back after a week off. Catch me up on Slack since 3 November in one page and list what needs my reply.
How it connects
- 1You add Slack once, signing in as yourself. The agent can read the channels and messages your account can, and your workspace may ask an admin to approve the app.
- 2You decide which agents get Slack. The Chief of Staff usually has it; give it to others only if their work is discussed there.
- 3Reading and searching need no approval. Posting in a channel, replying in a thread or sending a direct message asks first, with the exact text on the card.

Questions people ask
Can an AI agent post messages in Slack for me?
Yes, after you have seen them. A Monmo agent writes the update, the reply or the question and shows you the exact text, the channel and the reason. It posts when you allow it. One card can cover several messages, such as the same question sent to three people.
Can an AI agent summarise Slack channels?
Yes, on the schedule you set. Name the channels and the time of day, and the agent reads what was posted since its last summary and gives you decisions, open questions and mentions, each with a link to the thread. Summaries need no approval, because reading changes nothing. You can ask a follow-up about any line.
Can an AI agent read private Slack channels and direct messages?
A Monmo agent can read what the Slack account you connect can read, and no more. If that account is in a private channel, the agent can see it; if not, it cannot. You can tell it which channels to leave alone. Some workspaces require an admin to approve a connected app before it works.
How is an AI agent different from a Slack bot?
A Slack bot answers inside Slack when someone calls it. A Monmo agent is a team member with a role, its own computer and other apps, so it can read a thread, then check the tracker, the calendar and the document before it prepares a reply. You brief it in Monmo. It reads and posts through the Slack connection, falling back to Slack in its own browser for anything the connection leaves out.
