Sixty

Sixty is an AI assistant that filters email, calendar and your network into briefings, agendas and timely alerts, so only the work that needs you reaches you. It suits people whose day is mostly meetings and messages rather than hand-built task lists.

Sixty is an AI assistant built around the problem of digital noise rather than the problem of missing features. Rather than adding another inbox or task board, it sits on top of the calendar, email and your network, decides what deserves attention, and quietly handles or hides the rest. The product frames itself as a way to stop losing hours to work that software can absorb, so the time goes back to the things only a person can do. The core surfaces are briefings, agendas, a filtered inbox, alerts and outreach. Briefings pull together a summary of past interactions so a meeting starts with context already loaded. Agendas produce customizable snapshots of a day, a week or a weekend schedule, which is the closest thing to task management in the product: the plan is assembled for you rather than built item by item. Email is reduced to the messages that matter, alerts flag last-minute schedule changes and late notices only when they actually affect the day, and outreach tracks birthdays and milestones across your network so a greeting or gift does not slip. In practice Sixty behaves less like a to-do app and more like a chief of staff layer. You connect the accounts that hold your calendar and messages, then work from the generated view each morning instead of triaging everything yourself. The value compounds for people whose workload is mostly meetings, correspondence and relationships: founders, sales staff, consultants, executives and anyone juggling a wide professional network. Alternatives split along a different axis. Classic task managers expect you to enter and rank the work, while calendar tools stop at scheduling. Sixty's bet is that attention management, not list management, is the bottleneck, and it targets the moment of deciding what to ignore. Budget-conscious users should compare its filtering approach against the manual control those tools offer, because Sixty's leverage comes from trusting its judgment about what gets hidden.
