Zapier AI workflows are Zaps that include an AI step, such as AI by Zapier, the ChatGPT (OpenAI) integration, or a Zapier Agent. These steps let a Zap write text, generate images, analyze data, or make decisions, without requiring code.

What Is AI by Zapier?
AI by Zapier is an app built into the Zapier platform that adds AI steps to a Zap. Zapier rebuilt the app in October 2025 to make it easier to set up.
The updated AI by Zapier app runs on GPT-4o and does not require your own OpenAI API key. A prompt wizard drafts a prompt for you, or you can choose a template for tasks such as creating an outline from text or drafting an email reply.
The table below compares AI by Zapier with the ChatGPT (OpenAI) integration, which is a separate way to add AI to a Zap.
| Feature | AI by Zapier | ChatGPT (OpenAI) Integration |
|---|---|---|
| API key required | No | Yes, your own OpenAI account |
| Model | GPT-4o, included with your Zapier plan | Models available in your OpenAI account |
| Setup | Prompt wizard or template | Connect an API key, then build a prompt |
| Actions | Text generation and analysis | Chat, image generation, translation, classification |
How Do You Connect Zapier to ChatGPT?
Connecting Zapier to ChatGPT means linking your own OpenAI account to the ChatGPT (OpenAI) app on Zapier. This is different from AI by Zapier, which does not need an OpenAI account.
To connect ChatGPT (OpenAI) to Zapier, create an API key in your OpenAI account settings, then add it as a connection on the Zapier Apps page. Using GPT-4 models, including GPT-4o, requires a successful payment of at least $5 in OpenAI credits. ChatGPT (OpenAI) integrates with more than 9,000 apps on Zapier.
Once connected, the ChatGPT (OpenAI) app adds several actions to a Zap. Examples include:
- Send a chat message and generate a response
- Analyze an image
- Summarize text
- Translate text
- Classify text into categories
- Generate an image
How Does Zapier's AI Image Generator Work?
Zapier's AI image generator is the Generate Image action within the ChatGPT (OpenAI) integration. This action uses an OpenAI image model to create an image from a text prompt.
For example, a Zap can trigger when a new blog post is published, generate a featured image with the Generate Image action, then upload the image to a cloud storage app. Generating an image with this action counts as one task, the same as any other successful action.
What Are Zapier Agents?
A Zapier Agent is an AI tool that plans and carries out tasks based on instructions written in plain language. Unlike a standard Zap, an agent can reason about context and adapt its steps, rather than following a fixed trigger and action sequence.
| Aspect | Standard Zap | Zapier Agent |
|---|---|---|
| Steps | Fixed trigger and actions | Plans steps from instructions |
| Adapts to context | No | Yes |
| Oversight | Runs automatically | Can pause for human approval |
Zapier Agents connect to more than 9,000 apps and can use knowledge bases, such as documents or a company's existing data, to inform their decisions. Examples of agent features include:
- Guardrails, which limit what actions an agent can take
- Bring Your Own Model, which lets an agent use a chosen AI model
- Memory, which lets an agent retain context across a session
- Human in the loop, which pauses an agent for approval before certain actions
- An activity dashboard, which logs every action an agent takes
Multiple agents can be organized into a Pod, a group of agents that work together on related tasks. For example, a content Pod might combine an agent that drafts blog posts with an agent that schedules social media posts from that content.
An agent can run on its own, or as a step within a Zap. For example, a lead qualification agent can score a new form submission, update a CRM record with the score, and notify a sales team in a chat app.
How Do Zapier Agents Compare to n8n's LangChain Integrations?
Zapier and n8n take different approaches to agentic workflows. Zapier Agents work inside the Zap editor, using plain language instructions and pre-built app connections. This approach favors users without coding experience.
n8n connects AI agents using LangChain nodes. These nodes give developers control over the model, prompt, and memory at each step, and support connections to vector databases for retrieval-augmented generation. This approach favors users who want detailed customization.
Zapier Agents retain context within a session through Memory. n8n's LangChain nodes support persistent memory across sessions, using databases such as Redis or Postgres. Both platforms can connect to models from providers such as OpenAI, Anthropic, and Google.
What New AI Features Did Zapier Add in October 2025?
Zapier released several AI-related updates in October 2025. Examples include:
- A rebuilt AI by Zapier app, running on GPT-4o without a separate API key
- Tables, Interfaces, and Zapier MCP included in the Free, Pro, and Team plans
- The ability to share MCP server tools with other users
- New templates for AI by Zapier, covering tasks such as creating an outline from text
MCP stands for Model Context Protocol. It is a standard that lets AI models and agents connect to external tools and data sources. Sharing MCP server tools lets a Zapier account expose its connected apps as tools for AI models to use. Tables can store data that an Agent uses as a knowledge base, and Interfaces can provide a front end for an AI-powered tool, connecting the October 2025 plan changes directly to AI workflows.
What Is Code by Zapier, and How Does AI Help With It?
Code by Zapier is a step that runs custom JavaScript or Python within a Zap. It is useful for transforming data between an AI step and the next action, such as reformatting a ChatGPT response before it reaches a spreadsheet.
Zapier includes AI-assisted steps for writing and formatting code. These tools can draft a Code by Zapier step from a plain language description, which reduces the need for the user to write code directly. A Code by Zapier step counts as one task when it runs successfully.
How Do AI Zap Templates Work?
An AI Zap template is a pre-built workflow that already includes an AI step, such as AI by Zapier or a Zapier Agent. Templates provide a starting point that a user can adjust without building a Zap from scratch.
Zapier offers more than 80 pre-built agent templates, covering tasks such as lead qualification, content drafting, and customer support replies. Each template can be customized in plain language, then connected to the user's own apps and accounts. Using a template does not remove the task usage of the steps it contains. Each successful action in a template Zap still counts as a task.
What Are Common Use Cases for Zapier AI Workflows?
Zapier AI workflows combine AI steps with regular Zap actions to handle tasks across an app stack. Examples include:
- Summarizing incoming support emails with AI by Zapier, then creating a ticket with the summary attached
- Generating a product image with the ChatGPT (OpenAI) integration, then posting it to a social media app
- Using a Zapier Agent to qualify new leads from a form, update a CRM record, and notify a sales channel
- Extracting key details from an uploaded document with AI, then adding a row to a spreadsheet
- Using Code by Zapier to reformat an AI response before it reaches a Table or another app
Each of these workflows combines a trigger, one or more AI actions, and one or more standard actions. Tasks are counted for each successful action, including AI steps.
Frequently Asked Questions About Zapier AI Workflows

He is not a developer by training and not a SaaS founder. He is the person in the Discord server who actually answers the question instead of linking to the docs.
His writing on n8n Automation Tutorial covers self-hosting, AI agent workflows, tool comparisons, and the security vulnerabilities the automation industry would rather not discuss. He has built AI-assisted invoice approval flows using OpenAI function calling, connected Claude via HTTP Request nodes, and holds considered opinions about Zapier, Make.com, LangChain, and CrewAI that their marketing teams would not appreciate.
