ChatGPT for Outlook

What is ChatGPT for Outlook?
ChatGPT for Outlook is a free Outlook add-in from Blueberry Consultants that runs OpenAI's ChatGPT on messages in your inbox or while you compose new mail. You install it with a manifest URL, connect your own ChatGPT API key, and write custom prompts to summarize threads, pull out key details, or reshape email text without leaving Outlook.
The add-in is built for people who already rely on ChatGPT and want that workflow inside email. You can process a full message or narrow the scope to the body, subject, or attachments, then view results in a separate window or replace the original content. Multiple prompt configurations let you match different inbox scenarios.
Blueberry also offers custom branded versions for teams and resellers, with prompts and API keys tailored to a Microsoft 365 domain. The product is not affiliated with OpenAI or Microsoft, though Blueberry is a Microsoft Partner.
