Gmail
Matcha supports two ways to connect to Gmail:
iCloud
Matcha requires an app-specific password to access your iCloud Mail account. App-specific passwords are available only after two-factor authentication is turned on for your Apple Account.
AI Rewrite Plugin
Matcha includes an ai_rewrite.lua plugin that allows you to rewrite email drafts using an AI model. By default, it works with any OpenAI-compatible API.
Outlook
If you have a personal Outlook or legacy Hotmail account, you won't be able to authenticate with Matcha normally using OAuth without some special configuration. In this guide, we will create a Microsoft Entra App, give that app the required scopes and permissions, and then authenticate to that app with Matcha's OAuth tool.
