Mailr is an AI Email Assistant designed to write and reply to emails utilizing the capabilities of OpenAIs GPT-3/Chat-GPT. Aimed at transforming the way in which individuals and businesses manage and optimize their email communication, Mailr generates emails according to the user's intended goals and desired tone.

The user begins by providing the intention of the email in a few words, which are then developed into a comprehensive message by the assistant. The user can select from a variety of custom tones such as friendly, informal or persuasive.

Whether its a formal business email or a casual message to a friend, Mailr generates highest quality emails for any scenario. The utility also promises to secure users' privacy, with reassurances that user emails are never stored on servers and user data is never shared with third parties.

It operates with a simple interface made accessible through a Chrome extension. Users have to create an account for authentication, after which they can start utilizing the Mailr services.

Currently, Mailr supports only Gmail, with support for Outlook planned for future inclusion.
