AI by Zapier is a built-in tool that lets you create your own action in a Zap, powered by popular AI models. You can connect your own account from one of the available providers or use a built-in connection.
AI by Zapier lets you extract data, analyze information, and generate content by either:
- Using the prompt assistant to create a prompt.
- Selecting a template for common tasks.
- Copying an existing prompt.
Available on plans:
Free
Professional
Team
Enterprise
Overview
There are three main fields:
- Prompt: describe what you want the action to do.
- Input fields: fields that provide additional context to your prompt.
-
Output fields: fields that the action should create.
- You can map output fields to subsequent steps in your Zap.
- Output fields help structure the result of your AI by Zapier step.
AI by Zapier works best in the prompt builder mode.

Supported AI providers
You can only use models that your account admins or owner have allowed or have not restricted. Learn more about managing access to apps.
1. Add an AI by Zapier step
- In your Zap, click the + icon to add an action step. A dialog box will open.
- In the search box, search for and select AI by Zapier. The right sidebar will expand into the prompt builder mode.
2. Select a model
- Below the Prompt field, click the model dropdown to open the tier and model selector.
-
Select a model tier:
- Standard (1x tasks): Best for high volume, simple tasks. Tools and knowledge sources are not available on this tier.
- Advanced (3x tasks): Stronger reasoning for complex prompts and tool usage. This is the default selection for new steps.
- Premium (5x tasks): Complex analysis, tool usage, and multi-step reasoning.
- Bring Your Own Key (1x tasks): Use your own AI provider account with a 1x task rate, including tool calls. Learn how to connect your own AI provider.
- Select a specific model within your chosen tier. The Auto option lets Zapier pick the best model for your workflow.

Standard model steps use 1 task per run. If you select Advanced (3x) or Premium (5x), your step uses tasks at that tier's rate per run. If your step uses a tool, each call incurs an extra cost. Learn more about AI by Zapier model tier pricing.

Limitations
- AI by Zapier does not learn from previous actions. Each time an AI by Zapier action runs, the AI knowledge is reset to its initial state.
- AI by Zapier uses large language models (LLMs) from Zapier’s AI Functionality Subprocessors. Your AI by Zapier step may fail if its content violates the subprocessors’ usage policies.
- AI by Zapier cannot search and extract information from websites or any URLs.
- You can include up to 20 knowledge sources in each AI by Zapier step.
- Knowledge sources are stored in your Zapier account until you delete the specific content or entire Zap from within the product.
- When using image analysis, ensure your image URL is directly accessible. For Dropbox files, use the "Direct File link" rather than the "Share Link" to ensure AI by Zapier can properly access and analyze the image.
If you need advanced AI controls, you can use one of the many AI apps on Zapier.
