Clockwise - AI Calendar Optimizer

Overview

Clockwise was an AI-powered calendar optimization platform that automatically rearranged meetings and protected focus time to help individuals, teams, and organizations reclaim valuable hours for deep work. The platform's AI models ran up to one million calendar permutations per team per day to create the best possible schedule for everyone.

Important Update

The Clockwise team joined Salesforce in early 2026. Customer support was available until March 27, 2026. Clockwise partnered with Reclaim.ai to provide a smooth transition for users looking for AI-powered scheduling and calendar optimization.

Key Features

Flexible Meetings

When users marked internal recurring meetings as "flexible," Clockwise could move them to times that work better for all attendees. This feature only worked with internal attendees from the same organization.

Focus Time Creation

Clockwise optimized for 2+ hour blocks of Focus Time when possible, but scheduled 60-90 minute blocks when weeks filled up. The system automatically protected time for deep, uninterrupted work.

AI Assistant (Prism)

Users could interact with Clockwise via Prism, an intuitive chat + drag-and-click interface that provided shortcuts for scheduling and automated calendar management tasks.

Calendar Integration

Featured seamless integration with Google Calendar and Microsoft Outlook, syncing across all user calendars and team members.

Optimization Schedule

Flexible meetings optimization ran once daily at 4:00 PM in the organization's time zone, with a 20-hour protection window preventing last-minute changes.

Impact & Customer Base

Served over 40,000 organizations including:

• Uber
• Netflix
• Atlassian
• Asana
• Instacart

Clockwise created more than 4 million hours of focus time for teams worldwide during its operation.

How It Worked

AI Optimization Process

1. Analyzed team calendars and meeting patterns
2. Identified flexible meetings that could be rescheduled
3. Ran millions of permutations to find optimal arrangements
4. Automatically rescheduled meetings to create contiguous focus blocks
5. Balanced individual preferences with team coordination needs

Focus Time Protection

The system prioritized creating uninterrupted blocks of time by:

• Identifying gaps in schedules
• Moving flexible meetings away from potential focus periods
• Coordinating across team members to align focus time
• Protecting mornings or afternoons based on user preferences

Limitations

Organizational Boundaries

Flexible meetings only worked with internal attendees from the same organization. External meetings remained fixed.

Optimization Timing

Optimization ran once daily (4:00 PM organizational time), not continuously throughout the day.

Protection Window

A 20-hour protection window prevented last-minute changes, meaning meetings within 20 hours couldn't be automatically rescheduled.

Legacy and Transition

While Clockwise pioneered AI-powered calendar optimization, its acquisition by Salesforce in 2026 marked a transition point. The company partnered with Reclaim.ai to ensure users could continue benefiting from similar AI scheduling capabilities.

Impact on Industry

Clockwise helped establish several key concepts:

• AI-driven meeting optimization
• Automated focus time protection
• Team-wide calendar coordination
• Quantifying the value of uninterrupted work time

The platform demonstrated that intelligent automation could significantly improve knowledge worker productivity by optimizing the use of calendar time.
