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.

Make student thinking visible with AI-supported discussion and writing
An inquiry-based discussion platform with built-in AI coaching that helps students ask better questions and write stronger responses.
Pedagogy-first writing feedback that gives students formative input in real time and automates routine grammar and structure evaluation for instructors.
Newer assignment types like Teach the AI let students demonstrate understanding by explaining concepts to a curious AI learner.
An originality tool that reduces false positives and encourages students to revise before submission rather than punishing them after.
