In the world of productivity and automation, Zapier has long been the go-to tool for connecting your favourite apps and automating workflows. Now, with the OpenAI integration, Zapier becomes smarter — enabling AI-powered automation that can understand, generate, and respond just like a human.
Whether you're a product manager, analyst, or founder, Zapier + OpenAI empowers you to build intelligent workflows without writing any code.
What is Zapier?
Zapier is a no-code automation platform that lets you create Zaps — workflows triggered by events between different apps (e.g., "If I get a new email → Save to Google Sheet").
It supports over 6,000+ apps including Gmail, Slack, Trello, Airtable, Notion, Salesforce, and many more.

Zapier allows you to plug OpenAI’s GPT models into your Zaps. This means your automation can now:
- Understand natural language

Essentially, you’re adding cognitive intelligence to your automated workflows.
