Blueberry

Blueberry is a software development company that offers a free Microsoft Outlook add-in designed to integrate OpenAI’s ChatGPT directly into the Outlook email client. The add-in, called “ChatGPT for Outlook” (also referred to as AI Add-in for Outlook), allows users to apply ChatGPT’s natural language processing capabilities to email messages in two primary contexts: while reading messages in the inbox and while composing new emails. When reading an email, a user can select a message and invoke the add‑in to generate a summary, extract key points, suggest a reply draft, translate the content into another language, rephrase the email with a different tone (e.g., more formal or more casual), or perform any other text‑based task that ChatGPT can handle. The user provides a text prompt—such as “Summarize this email in three bullet points” or “Convert this email into a polite refusal”—and the add‑in sends the email content along with the prompt to OpenAI’s ChatGPT API, then displays the generated response directly inside the Outlook interface. While composing a new email, the add‑in can be used to help write the body of the message. For example, a user can type a few notes or bullet points, then ask the add‑in to expand them into a full, well‑structured email. Alternatively, the user can ask the add‑in to check grammar and spelling, improve clarity, adjust the length, or change the style. The add‑in supports any prompt the user can think of, limited only by the underlying capability of ChatGPT. This makes it useful for a wide variety of business and personal email tasks: drafting customer support responses, writing meeting follow‑ups, composing outreach emails, generating personalized marketing messages, or even translating emails in real time. The add‑in also includes featur
