How to Connect Slack to AI (Free Slack Summaries)

Slack moves fast. Step away for a morning and you come back to forty unread channels, three threads you were tagged in and a decision you somehow missed. Scrolling back through all of it is a job in itself.

Connecting Slack to AI turns catching up into a question. Ask what you missed and get the short version, with the threads that actually matter.

This guide shows how to connect Slack to Viro AI, the free AI assistant with ChatGPT, Claude, Gemini and Viro’s own model in one app, and what you can do once it’s connected.

What you can do when Slack is connected to AI

Catch you up on recent messages in channels you’re a member of, including private channels and group DMs
Search messages in public channels
Read and summarize a thread
Work across every Slack workspace you connect

What it won’t do: read one-to-one direct messages, search inside private channels, or post and reply in Slack. Viro reads; you do the talking.

How to connect Slack to AI, step by step

Open Viro AI at ai.viro.app, or in the iPhone, Android or Mac app, and sign in. It’s free.
Go to Customize → Connectors, open Slack and select Connect to Viro.
Sign in to Slack and approve access for your workspace.
Check that it’s connected. Back in Viro, Slack is listed under Yours.

Some workspaces require an admin to approve new apps. If yours does, Slack asks you to request approval, and you can connect once an admin approves Viro.

What to ask Slack once it’s connected

Once it’s connected, just ask in any chat. Use your own names and dates.

Catching up

“What did I miss in #marketing today?”
“Catch me up on my channels since yesterday afternoon.”
“Anything important in #engineering this week?”

Finding things

“Search Slack for the launch date.”
“Who mentioned the Acme contract, and what did they say?”

Long threads

“Summarize the thread about pricing.”
“What did we decide in the onboarding thread, and who owns the next step?”

Across your apps

With Notion connected: “Add a summary of today’s #product discussion to my Team Notes page.” With Google Calendar: “What did people say in Slack about tomorrow’s offsite?”

Read-only by design

Viro can’t post or reply in Slack, so there’s no risk of an AI-written message landing in a channel by mistake. When you want to respond, ask Viro to draft the message and paste it in yourself.

Good to know

You can connect more than one workspace: open Slack in Customize → Connectors, select Add workspace, and on Slack’s screen choose Sign in to a different workspace. Each workspace has its own switch, so you can pause one without disconnecting it.
When catching you up, Viro looks at up to 100 channels per workspace.

Is it private?

Viro reads your Slack data only to answer what you ask. It is never used to train AI models and Viro never sells your data. Free-plan ads are matched to words in the current conversation, never to your identity or your connected apps, and no human reads your chats.

To disconnect, open Slack in Customize → Connectors and select Disconnect next to the workspace. Viro also removes its access in Slack for you.

Why use Viro for Slack?

It can’t post. Summaries and search without the risk of a message going out.
More than one model. Ask with ChatGPT, Claude, Gemini or Viro’s own model, and switch mid-conversation.
Free. Connectors are included on every plan, including Free, on web, iPhone, Android and Mac.
All your apps in one place. More than 40 connectors, so one question can cover your email, calendar, files and work apps together.
Clean energy. Viro’s own model runs in data centers powered by hydro, geothermal and wind, and Viro funds new clean energy to match its partner models. See the data centers.

Connect Slack to Viro AI free. Full details are on the Slack help page, and every other app is listed in how to connect your apps to AI.
