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.

Collaborative inbox and email management for teams
Let multiple people work the same inbox with clear assignment, internal statuses, and visibility into who is answering what.
Discuss and prepare replies inside the email thread itself, so context stays attached and nobody is left out of the loop.
Turn any email into an assigned task and see what each teammate is working on today, tomorrow, and next week.
Automate repetitive routing, tagging, and follow-up with rules, rule templates, and workflow automations.

Provides clean inbox prioritization and smart summaries, but lacks deep team chat integration and shared inbox workflow rules.
