# Creating ChatGPT Apps
ChatGPT apps are conversational experiences that extend ChatGPT through tools and custom UI widgets. They're built as MCP servers that ChatGPT invokes during conversations.
## Workflow
1. **Brainstorm**: validate the idea and create SPEC.md. See [references/brainstorm.md](references/brainstorm.md).
2. **Architecture**: specify tools and widgets, update SPEC.md. See [references/architecture.md](references/architecture.md).
3. **Bootstrap**: scaffold the project. See [references/bootstrap.md](references/bootstrap.md).
