Slack + Gemini integration
Connect Slack to Gemini
ConnectChats brings your Slack chats into Gemini. Ask Gemini to catch you up, find any message and draft replies. Nothing gets sent until you approve it.
Free to start. No app to install. Every send needs your OK.
What Gemini can do with your Slack
ConnectChats gives Gemini a small set of tools. Gemini calls them when you ask about your Slack chats, and only for the chats you share.
-
Catch you up
Ask what you missed and Gemini reads your unread Slack chats, then gives you the short version: who needs an answer, what was decided, what can wait.
get_messages_to_summarize -
Find any message
The address someone sent last month, the price a client agreed to, the link from a group chat. Gemini searches your Slack history and quotes the message.
search_messages -
Draft replies
Gemini writes the reply in your tone, in the chat's language, with the context of the whole thread. You read it, edit it, and send it.
draft_reply -
Send with your OK
When you approve a draft, ConnectChats sends it from your own Slack account and confirms delivery. Auto-send only runs in chats where you switch it on.

How to connect Slack to Gemini
It takes about two minutes. You do it once, and the same account then works in every AI app you add.
-
Add ConnectChats to Gemini
- In the Gemini web app, open Settings, then Connected Apps, and add ConnectChats with https://api.connectchats.com/mcp as the server URL.
- Gemini opens the ConnectChats sign-in page, where you sign in with your passkey.
- In a prompt, type @ and pick ConnectChats to use your linked chats.
-
Link your Slack account
- Open https://connectchats.com/app and choose Link a chat app, then Slack.
- Sign in to your Slack workspace with your own Slack account.
- ConnectChats lists your channels and direct messages, and you choose which ones to share with your AI app.
- To add another workspace, repeat the sign-in for it.
-
Pick the chats Gemini can see
Every chat is listed in your ConnectChats dashboard. Share all of them or only the ones you choose. Gemini never sees the rest.
-
Ask Gemini about your Slack
Open a new conversation in Gemini and ask about your chats. Gemini calls ConnectChats when it needs your messages.
How Slack and Gemini work together
ConnectChats links to Slack when you sign in to your workspace from the ConnectChats dashboard. Your AI app sees the channels and direct messages your own account can see. ConnectChats does not install a bot in your workspace or read channels you are not in.
-
Slack in ConnectChats
Direct messages, group messages and the channels you belong to are supported, including thread replies. Each linked chat starts with its last 200 messages, then every new message arrives as it is sent. On Slack's free plan, Slack only shows the last 90 days of messages, so older ones cannot be imported either. Messages your AI app sends go out from your own Slack account, after you approve them. The free plan links 2 chat apps and keeps messages for 30 days.

ConnectChats in Gemini
The Gemini web app can add custom apps from an MCP server URL on eligible accounts. Add ConnectChats once, sign in with your passkey, and pick it with @ in any prompt where you want Gemini to see your chats. Google limits custom apps in Gemini to people 18 or older in the US, signed in with a personal Google account, in English, with Keep Activity on. Work and school accounts are not supported. Custom apps are connected in the Gemini web app, then also work in the Gemini mobile app. The same ConnectChats account works in every AI app, so the chats you already linked are available in Gemini without linking them again. ConnectChats only sees the chats you choose to share, and it asks for your approval before any reply is sent.
Your Slack stays under your control
-
You pick the chats
Gemini only sees the Slack chats you share. Unshare a chat and it disappears from every AI app at once.
-
Drafts by default
Gemini prepares replies. You approve each one before it reaches Slack, unless you turn on auto-send for that chat.
-
Stored messages are encrypted
Stored messages are encrypted with a key that only your passkey can unlock. We never train models on your messages.
Questions
Can Gemini read my Slack messages?
Yes, once you link Slack in ConnectChats and add ConnectChats to Gemini. Gemini reads only the chats you share, and only when you ask it something that needs them.
Can Gemini send Slack messages for me?
Gemini can draft a reply and send it after you approve it. Messages go out from your own Slack account. You can allow automatic sending for specific chats, and it stays off everywhere else.
Is the Slack to Gemini integration free?
Yes. The free plan links two chat apps and works in every supported AI app, with no limit on what you ask. No card needed.
Do I need to install anything?
No. You add ConnectChats inside Gemini and link Slack from your browser. There is no app to download and nothing runs on your computer.
Does it work with other AI apps too?
Yes. The same ConnectChats account works in ChatGPT, Claude, Grok, Manus, Muse and any AI app that supports remote MCP servers. Link Slack once and use it everywhere.
Does my Slack admin need to approve ConnectChats?
ConnectChats signs in as you rather than installing an app in the workspace, so there is nothing for an admin to add. Some companies forbid third party clients in their policies, so check yours before you link a work account.
Does it see private channels?
Only the ones you are a member of, because it sees what your own account sees. You still choose which channels are shared with your AI app.
Can I use ConnectChats with Gemini today?
Yes, on accounts where Gemini offers custom apps. Add ConnectChats with https://api.connectchats.com/mcp in the Gemini web app under Settings, Connected Apps, then sign in with your passkey.
Will it work with a Google Workspace account?
No. Google does not offer custom apps in Gemini for work or school accounts, so use ConnectChats with a personal Google account.
