Generate Gmail replies with ChatGPT using your own OpenAI API key
A row of generation buttons appears next to the standard reply control whenever you start answering an email in Gmail.
You paste your own OpenAI API key once in the settings; all requests are billed to your own OpenAI account.
Each button maps to a different type of answer, from a short acknowledgement to a free-form custom response.
Generated text is placed straight into the Gmail reply box so you can review, edit, or send it immediately.

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.


Features a unified cross-platform inbox with AI assistants, but lacks Missive's advanced team collaboration and shared conversation assignment.
