Clockwise
AI calendar optimization that creates focus time by intelligently rescheduling meetings
What is Clockwise?
Clockwise was founded in 2016 with a specific thesis: calendars are broken, and AI can fix them. The insight is simple but powerful — most calendars are reactive, filling up with meetings that others schedule without regard for your deep work time. Clockwise's AI takes an active approach, analyzing your schedule, your colleagues' schedules, and your preferences to optimize when flexible meetings happen so your most focused hours are protected.
The core feature is Flexible Meetings. When a meeting is marked flexible, Clockwise can move it within a defined window to create focus time blocks — stretches of 90+ minutes without interruptions. It does this simultaneously across teams, finding meeting times that work for everyone while maximizing individual focus time in aggregate. Companies using Clockwise report significant increases in uninterrupted work time per week, which compounds into measurable productivity gains for engineering, design, and research roles.
Clockwise's AI assistant (Prism) went further in 2024, adding natural language calendar management. You can tell Prism 'schedule a one-on-one with Sarah sometime this week, avoid Monday mornings' and it handles the scheduling and coordination automatically. The free plan covers basic calendar optimization; Teams and Business plans add team-level features, priority support, and advanced analytics. For individuals with fragmented calendars, Clockwise's free tier alone is transformative.
