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.

AI email replies, multi-model chat, and workflow automations in one workspace
Generate replies, draft new messages, and produce multiple phrasing options from a Gmail sidebar without breaking your workflow.
Talk to several well-known AI models in one interface and pick the one that fits each research, writing, or summarization task.
Upload documents or point the assistant at a page to extract answers, summaries, and key points instead of reading everything yourself.
Create custom personas for professional, casual, sales, or support writing and train them on your own tone so output matches your voice.
