🧠 How to build your own slack thread summarizer AI agent

✅Build Your Own AI Agent in 7 Simple Steps

To set up your AI agent, we’ll use Zapier, a no-code automation platform that lets you connect your favorite apps and create powerful AI workflows.

🤖 Step 1: Open Zapier & Enable Agents

Head to your Zapier dashboard
→ Find “Agents” in the left menu
→ Click “Create Custom Agent”
→ Name it something practical like “Slack Daily Summary”

🖥️ Step 2: Explore the Agent Interface

• Once the agent is created, you'll see its interface.

• This displays all the behaviors (including those from previous agents, if any).

• You can always return to check the agent’s activity and progress.

▶️ Step 3: Create a New Behavior

Click “Run Behavior” → “Create Behavior”
This is where you’ll tell the agent exactly what task it should perform.

🎮️ Step 4: Set the Trigger

• Click “Add Trigger” and choose an app to start the workflow.

• For this example, select Slack.

• Set the trigger to “Reaction Added” (this means you can trigger the agent by adding an emoji reaction to any message)

🛠️ Step 5: Define the Behavior

Write a simple prompt like this:

This tells the agent what to do—clearly, concisely.

🔥 Step 6: Add Tools to Make It Happen

Now we tell the agent how to complete the task:

1. Click “Insert Tool” and search for Slack.

2. Choose “Retrieve Thread Messages” – this lets the agent pull the full thread details.

3. Click “Insert Tool” again and select Gmail.

4. Choose “Send Email” as the action.

• For the thread timestamp, you can either manually set it or let the agent generate the value automatically.

• Enter the desired recipient email address.

🧪 Step 7: Save and Test

Click Save → then Test Behavior
Now, react to any Slack thread, and you’ll get a summary in your inbox. Clean, fast, and actually useful.

🎉 That’s it!

This isn’t just a one-off automation.
You now have a working AI agent that saves your brainpower for things that actually matter.
And if this setup clicked for you—you can use the same logic to:

 ✅ Auto-send weekly team updates

 ✅ Summarize meeting transcripts

 ✅ Sort your calendar highlights

 ✅ Or build your own custom workflows

All without touching a line of code.. 🧑‍💻

🎁 Bonus Drop: Build-Worthy AI Agent Ideas

We got a comment asking for more use cases beyond Slack.
Fair ask. We heard you. And we’re delivering.

Here are some practical, creative AI agents you can build across platforms you already use:

🧠 The Mood Reader (for internal emails, LinkedIn DMs, or even team chat)
Analyzes your inbox or messages daily and alerts you when someone’s tone shifts — frustration, hesitation, burnout vibes. A quiet way to stay emotionally in sync with your team, clients, or network.

💡 The Idea Refiner (perfect for LinkedIn post drafts, meeting notes, or saved voice memos)
Collects rough ideas you jot down (in Notes, Google Docs, Notion, etc.), improves and expands them using GPT, and sends you 3 polished versions every Friday — ready for publishing or pitching.

📸 The IG Recap Agent (for creators or marketers)
Pulls your best-performing Instagram posts from the week, summarizes comments + DMs, and suggests what to post next — based on engagement trends and topic overlap.

🕵️ The Meeting Ghost (yes, this one’s a keeper)
Reads your video meeting transcripts and pulls out the actual action items, key decisions, and follow-ups. Sends you a tight recap before you’ve even left the Zoom window.

💬 The LinkedIn Lead Nurturer
Watches for new comments or DMs on your posts, checks for potential leads or collab requests, and drafts a personalized response you can review and send — instantly keeping your network warm.
