Develop Google Chat apps

Use the Google Chat API to build Chat apps that bring your services and resources right into Google Chat, letting users get information and take action without leaving the conversation.

Answer questions based on Chat conversations with a Gemini AI Chat app

Build a Chat app that answers questions with generative AI: when someone asks a question, the app checks for previously shared answers and then shares one.

Respond to incidents with Chat, AI, and Apps Script

Build a Google Chat app that responds to incidents in real time. The app creates a Chat space, facilitates incident resolution, and uses AI to summarize the response in Google Docs.

Manage projects with Google Chat, Vertex AI, and Firestore

Make a Google Chat app that a team can use to manage projects in real time. Help users write user stories with generative AI-assisted story writing tools.

Build interactive cards that help people get work done

Cards provide a standard interface that ensures your Chat app looks good on any device. Interactive elements like buttons enable users to do their work directly from Google Chat.

Simplify complex interactions

Dialogs are windowed, card-based interfaces that Chat apps open to interact with users. Help users complete multi-step processes with sequential dialogs.

Promote productive collaboration

With link previews, whenever users share links in Google Chat spaces, your app can attach cards with helpful information that let people take action right from Google Chat.

Call the Chat API
