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.
Speak once and get it done — VoiceOS turns your voice into actions across every app.
Say what you want done and VoiceOS performs it in the right app — sending emails, filing tickets, scheduling meetings and finding files.
Speak instead of typing and get clean, professionally formatted text with filler words stripped out and grammar corrected automatically.
Point your cursor at anything on screen to give VoiceOS context, so you can ask questions and issue commands without long explanations.
Audio is never stored on the servers or used to train models, and transcripts are saved locally on your device under your control.
