Turn rough Gmail drafts into polished, professional messages with OpenAI
A magic-button action is added to the Gmail compose window, so you can rewrite the draft you are already writing without switching tabs or copying text elsewhere.
The rewrite targets professionalism and respect, turning terse or overly casual phrasing into wording better suited to colleagues, managers and clients.
You connect the extension to OpenAI with your own API credentials, keeping usage costs transparent and under your control.
There are no settings to configure beyond the API key and no new writing interface to learn — it works inside the Gmail compose box you already use.
