Zephyr automatically summarizes emails, extracts tasks, drafts replies, and handles repetitive work--so you don't have to.
Works inside Outlook. Set it once, let it run.
Zephyr watches your inbox around the clock. When emails arrive, workflows kick in automatically--summarizing, replying, extracting tasks, and routing to your tools.
New emails trigger workflows that extract action items and send them to Jira, Asana, Trello, or Linear--without you lifting a finger.
Incoming messages get contextual draft replies based on the full thread. Review and send, or let Zephyr handle it.
Slack messages, HubSpot contacts, Notion pages, Google Sheets rows--all updated automatically when the right email arrives.
Follow-up reminders, SMS alerts, and Teams notifications ensure important emails never get buried.
From inbox to done, without lifting a finger.
A new message lands in your inbox
Key points extracted in seconds
Action items pulled into your workflow tools
A contextual response ready to review
Optionally sends the reply for you
Just type what you need. Zephyr understands plain English--summarize this thread, draft a reply, check my calendar, triage my inbox.
Or use one-tap shortcuts for common actions like summarize, draft, and extract tasks.
