What is ChatGPT for Outlook?

ChatGPT for Outlook is an add-in that integrates OpenAI's ChatGPT directly into Microsoft Outlook. It allows you to compose, refine, and respond to emails using AI assistance without leaving your inbox. The tool works as a browser extension or native add-in, giving you access to ChatGPT's language capabilities whilst working with your email. It's designed for professionals who handle high email volumes and want to save time on writing and editing messages. The freemium model means you can try basic features without paying, though advanced usage or higher quotas may require a subscription.
