How it works

Three steps from WhatsApp to Slackbot

  1. 1

    Start your free trial

    Connect your WhatsApp number to TimelinesAI.

  2. 2

    Connect Slackbot to your account

    Sign in once from Slackbot. No API key.

  3. 3

    Ask Slackbot

    “Which chats still need a reply?” “Summarize my chat with Sarah.” “Reply that Friday works.”

What you can do

Run your WhatsApp inbox in plain language

66 tools for chats, messages, templates, labels, assignees and more, all available from Slackbot.

01

Know where every conversation stands

Ask for a summary and Slackbot reads the chat history for you: what the customer asked, what is still open, and whether anyone has replied.

Try askingSummarize my latest chat with Sarah Johnson.
02

Let AI work through your inbox

One request can find unanswered chats, read them, summarize each one and draft replies for the urgent ones. You review before anything goes out.

Try askingCheck my unanswered chats from today, summarize each one, and draft replies for the urgent ones.
03

Reply to customers, with your approval

Slackbot shows the exact message and asks before it sends. Choose Allow Once to approve a single send.

Try askingReply to Sarah: Friday at 3 PM works. I'll send the quote today.
04

Send approved WhatsApp templates

Work with WhatsApp Business API numbers and message templates from Slack. Meta's own per-message fee for template messages still applies.

Try askingSend the appointment_reminder template to Daniel Brooks for tomorrow at 10 AM.
05

Keep your team organized

Add labels, assign a teammate and leave an internal note on a chat. Nothing is sent to the customer.

Try askingIn my chat with Sarah, add the label Hot lead, assign it to Maria, and add a note.
06

One shared inbox for the whole team

See which chats nobody owns and hand them to a teammate, without opening another tab.

FAQ

Questions about WhatsApp in Slack

What is TimelinesAI for WhatsApp?

A Slackbot app that connects your TimelinesAI WhatsApp inbox to Slack. You ask Slackbot in plain language to find chats, read and summarize them, add labels and notes, and draft or send replies, using 66 tools.

Which Slack plans does it work on?

Slackbot is available on Slack Business+ and Enterprise+ plans.

Do I need a TimelinesAI account?

Yes. You need an account with at least one WhatsApp number connected. Start with the 10-day free trial, no credit card needed.

Do I need the WhatsApp Business API?

No. TimelinesAI works with your existing personal or business WhatsApp. Scan a QR code and chats start syncing. Business API numbers and Coexistence are supported too.

Can Slackbot send messages to my customers?

Only with your approval. Slackbot shows the action and asks before it runs. Sends are real and immediate, there is no undo, and customers cannot tell the message from one you typed in TimelinesAI, so check the text before you approve. If you only want drafts, ask for a draft first and send it yourself.

What should I be careful with in the approval prompt?

Allow Once approves one action. Always Allow skips the prompt for that tool from then on. Use it for read-only actions such as listing chats, not for sending.

Who can see my chats?

The app acts as you. Your existing TimelinesAI role and permissions apply exactly as they do in the TimelinesAI app.

Does it use AI? Can it be wrong?

Yes. Slackbot uses AI, and summaries and drafted replies can contain mistakes. Check them before you send.

Does it cost extra?

No. It is included in every TimelinesAI plan. Messages use your monthly messaging quota, and tool calls count as API calls. Meta charges its own fee for WhatsApp Business API template messages.

Does it work with ChatGPT or Claude too?

Yes. The same TimelinesAI MCP server works with ChatGPT, Claude, Cursor, Codex and other MCP-compatible assistants. See timelines.ai/whatsapp-mcp.
