ChatGPT for Outlook is a third-party Outlook add-in that brings AI features into the email client to help you process emails.
You need a valid Microsoft 365 account, and users typically need to supply and configure an OpenAI API key themselves.
Main features include smart drafting and polishing of emails, generating content summaries, translating text, and supporting handling of specific email scenarios via custom prompts.
Using the plugin typically involves OpenAI API usage fees, calculated based on request volume and model type. The plugin itself may offer a free basic version and paid enterprise customization.
Data security depends on the specific plugin implementation and user configuration. When using it, pay attention to the required permissions, and it is recommended to manually review AI-generated content.
Third-party add-ins generally offer broader in-app interactions (compose, send, etc.) within Outlook, while OpenAI's official integration is designed for securely reading email and calendar data within ChatGPT.
