Swizero is an AI-powered email app designed to help people manage their inboxes quickly and focus on what matters. It scans incoming messages, summarizes them, and ranks them using urgency, sender importance, and context. Emails appear as a manageable stack of cards, allowing users to clear, flag, archive, or delete messages with a swipe. Swizero can also generate contextual reply drafts for users to review and edit; messages are never sent without approval.

The service includes subscription management to surface newsletters for unsubscribing, smart triage that suggests actions, and Sweep, which groups messages from the same sender for batch handling. Users can complete a “Swizero Run” to clear important messages and track daily streaks and time saved. Swizero emphasizes privacy, stating that email ranking happens on the user’s device and AI processing uses providers that do not retain emails or train on them. The brand is currently inviting people to join its early-access waitlist.
