An all-in-one AI super assistant for professionals and enterprises
A single chat interface that gives access to a broad catalog of frontier language models, with the ability to switch or compare models per prompt.

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.
