Staring at a blank screen, trying to come up with your next viral video idea? It's no surprise if—between researching topics, writing scripts, creating captions, and managing all the moving pieces—the perfect moment to capitalize on a trending topic slips away from you.

With Zapier Agents, you can build an AI agent that helps you avoid those missed opportunities. It'll automatically handle your entire pipeline, so instead of spending hours on research and first drafts, you can focus on filming great content and connecting with your audience.

Watch the video below to see how this agent works, or keep reading for step-by-step instructions.

I'm going to show you how to use this Viral Content Creation Agent template on Zapier Agents. And this page goes into essentially how the template works. You can review it for the basics and also the tools that are connected under Capabilities.

But I'm going to go over all this as we go through, so let's get started by clicking Use Template. On this page, there's nothing you can actually change yet. It's really just an overview of the instructions that the agent is going to use verbatim. So it's a good summary of the logic behind it, if you want to check that out before jumping in. It also shares the specific trigger that's going to work in tandem with the agent. And the last thing that I'll point out is that it also shows you whether or not it's an official Zapier template. You can check that for yourself by looking at this little checkmark here that says Zapier. And so since we can't change anything here yet, let's go ahead and click Use this template.

So the next step with using any of these agent templates, it typically involves connecting the different tools that make the agent run. And so as you can see, it's suggesting a couple of accounts that I've been using recently and that I already have connected to other Zapier workflows and automations. What's really cool is that you don't necessarily have to reconnect accounts that you already connected in other parts of Zapier. You'll be able to access them here. That being said, if you did want to connect some different accounts, if you wanted to add a new account, there are two ways to do it. It's either by clicking this widget and clicking Connect New Account or Manage Accounts, or by clicking this dropdown here and clicking the button.

I'm going to go with the Slack account that's already selected here and the Google Docs account, and I'm just going to connect the same Google Drive account. I'll note that—like it says here—this isn't the only opportunity that you have to connect these apps and these different tools that the agent's going to use. But I'm not going to—for the way that we're going through this agent—change my selections here. I'm just noting that if you did want to change them, then you will have another opportunity to do it. It's not only here.

So let's move forward by clicking Create. All right, so this is the agent itself, and you can interact with it. You can change the instructions if you want. I'm not going to be changing the instructions, but I'll try to give you some ideas for how you might customize this for your own workflow. Let's go through each of the things that you're seeing on the screen here, step by step.

So one of the first things is the trigger, and this one is triggered by a schedule, and in this case, it's scheduled by day. You could change it to every hour. You could change it to certain days. It's very flexible in terms of how you want it to run, how it makes sense for your workflows. There are other triggers, including different apps and actions within those apps that can trigger an agent. Another trigger that you'll come across if you check out more of these templates (or as you build different Zapier agents) is the on-demand trigger. Many of these agents work in the background autonomously based on those triggers, but the on-demand agent is one that you chat with in order to get it to execute its instructions. Every trigger, except for on-demand, requires that you flip it on with this toggle here that says Enable. If you want to use the agent outside of the testing that we're doing now, make sure that you click to enable the agent.

We've gone over the trigger. Now we can talk about the instructions. It says, "You are a content automation agent, and your goal is to research trending topics in the business niche." This you actually do have to personalize. Let's say that we want to put AI consulting as the niche. Create viral video scripts and supporting assets, configure engagement automation, and deliver everything in a shareable document with notifications. We do this with the connected tools and the logic of each step here. The first step, breaking that down, is topic research and selection, with three sub-steps of searching online for three trending topics in AI consulting, evaluating each for viral potential on TikTok short and long form, and selecting the best topic for further content creation.

The next step is content scripting: draft a five-second attention-grabbing hook that is controversial or viral, write an 80-second short video script with clear value, storytelling, and a call to action, expand into a five-minute long-form video script with full sentences and B-roll shot suggestions, generate captions for both short and long-form videos, and include up to six relevant hashtags. Create a two-paragraph, direct-response-style newsletter post to promote the videos.

There are a lot of steps here. But there is great potential once you know what you want it to focus on. It can help execute those steps with a first draft for each one. This is also a great place to customize the agent according to your needs. Maybe your newsletter isn't two paragraphs, maybe your videos are a different length, maybe you care about Instagram instead of TikTok. The more detail you give it, the better results you'll get. You might even create agents for different aspects of your business. But whenever AI generates content, treat it as a first draft—validate the points it makes and ensure you agree with the ideas before publishing.

Step three, document notify, compiles all scripts, captions, and the newsletter into a Google Doc. We have these tool calls: Google Docs (create document from text), Google Drive (add file sharing preference), and Slack (send direct message). You could customize the tools—like setting a fixed document name or folder—but the default lets the agent generate values for these fields, which makes setup flexible.

Now we're going to test the agent. This interface is similar to an on-demand chat, but because this isn't an on-demand trigger—it runs in the background. You'll still see the logic in the Activity tab as it works. It starts by asking whether to use Google search to find trending AI consulting topics or a preferred source. In a live run, it would decide on its own, but during testing you can weigh in. It uses Google Search even though it wasn't explicitly listed in the instructions—Zapier Agents can use certain tools automatically if the natural language instructions call for them. It extracts and evaluates three trending topics from expert sources, then gathers two more to complete the shortlist. It evaluates them and selects the best: “Agentic AI and the Real Value of Generative AI: Hype vs. Reality.” It then begins creating scripts and assets: generating a hook, an 80-second script, a five-minute script, captions, hashtags, and a newsletter post. You can customize these outputs—like limiting hashtags or changing formats.

Once the content is ready, it creates the Google Doc, updates sharing permissions, and sends the link in a Slack direct message. You can customize the Slack message as well. At the end, the doc is available in both the Activity log and your Slack DMs. The last step is to enable the agent with the toggle so it runs on schedule. You can view all workflow runs in the activity tab.

This is a powerful, customizable way to create an efficient marketing workflow for your niche, based on trending topics people are talking about. Customize it, run it, and see what you can create.

How to set up a viral content creation system with Zapier Agents

Let's start with a ready-to-go template for Zapier Agents. This agent auto-researches trending topics in your business niche, creates viral video scripts for you, and compiles everything into a shareable document.

The agent uses the Schedule by Zapier trigger to run daily. During each workflow run, the agent searches for three trending topics in your niche, evaluating each for viral potential on platforms like TikTok. It then creates attention-grabbing hooks and full scripts, generates supporting assets like captions and hashtags, and adds everything to a Google Doc. When it's done, you'll get notified in Slack.

Keep in mind that this agent is designed to provide first drafts of content. You should always validate any points it makes and verify that you agree with the ideas it presents. Use it as a powerful brainstorming assistant rather than a one-and-done content creator.

To get started, click on the button below, then follow the steps to customize your agent.

Step 1: Activate the template

  1. Navigate to the Viral Content Creation Agent template.

  2. Click Use Template to start building in Zapier Agents.

  3. Review the summary of the agent's instructions and trigger.

  4. Click Use this template.

Step 2: Connect Slack, Google Docs, and Google Drive

After reviewing the template summary, you'll need to connect the tools that'll execute the agent's functionality.

  1. Connect your Slack account. You can use a previously connected account from other Zapier automations or connect a new account.

  2. Connect your Google Docs account for document creation.

  3. Connect your Google Drive account to share permissions and manage files.

  4. After all your accounts are connected, click Create.

Note: If you change your mind or add things after the fact, you can connect or change accounts later in the setup process.

Step 3: Review and customize your agent's trigger

The trigger is set to Schedule by Zapier by default, configured to run daily. This automatic scheduling ensures you get fresh trending content ideas every day without manual intervention.

Want alternative options? Just modify the trigger's schedule. For example, you can set it to run:

  • Every hour for more frequent content generation

  • On specific days to align with your content calendar—for example, every Monday, Wednesday, and Friday, or targeting key dates that fall on product launches, holidays, or industry events

  • At custom intervals to match your publishing schedule—for example, every three days, twice weekly, or at a flexible interval that's based on your workflow and audience engagement patterns

Step 4: Review and customize the agent's instructions

The agent follows a content creation workflow in which there are three main phases:

  1. Topic research and selection: The agent searches online for trending topics in your business niche, evaluates viral potential, and selects the best topic.

  2. Content scripting: The agent creates five-second hooks, 80-second short-form scripts, five-minute long-form scripts with B-roll suggestions, captions, and hashtags, and newsletter posts.

  3. Documenting and notifying: The agent compiles everything into a Google Doc, sets sharing permissions in Google Drive, and sends Slack notifications to keep you in the loop after each successful workflow run.

Important: You must personalize the business niche in the agent's instructions. The template uses [BUSINESS_NICHE] as a placeholder, which needs to be replaced with your specific focus (for example, AI consulting, wellness, or eCommerce).

The agent uses several connected actions, including Google Docs: Create Document From Text, Google Drive: Add File Sharing Preference, and Slack: Send Direct Message—and it has automatic access to Google Search for trend research.

You'll also notice widget icons next to each tool that allow flexible configuration. The agent can generate values automatically, or you can set specific parameters.

Here are a few ways you could customize this agent:

  • Content formats and lengths: Adjust video lengths, caption styles, or newsletter format to match your brand.

  • Platform focus: Replace TikTok with Instagram, YouTube, or other platforms relevant to your audience.

  • Document organization: Set specific naming patterns or folder locations for consistent file management.

Step 5: Test and deploy your agent

  1. Click Test agent to run a sample workflow and see how the content creation process works.

  2. The agent will walk you through each phase: topic research results, script generation, and document compilation.

  3. Review the proposed actions and click Approve to see each step execute. You'll only need to go through this approval process when testing your agent, not when it's running live.

  4. You must manually enable the agent after testing using the Enable agent toggle. Keep in mind that this is required for scheduled triggers, unlike on-demand agents, which are automatically enabled.

Once deployed, you can monitor the agent's daily output through the Activity tab, which shows workflow runs, selected topics, generated scripts, and links to created documents.

Customize your viral content creation agent

This template gives you a powerful foundation for automated content creation that you can adapt to your specific niche and workflow needs. It's all customizable. Change up the research sources, adjust content formats for different platforms, or integrate with additional tools for a more complete content management system.

Whether you're running multiple versions of this agent for different aspects of your business or customizing this one extensively for your unique workflow, the key is experimentation. Iterate. Find what works best for your brand's distinct content strategy.

And this is just one example of what Zapier Agents can do. For more inspiration on ways to build agents, head to our Zapier Agents guide.
