Compare features, pricing, pros & cons, and user ratings to decide which AI tool is best for your needs.
Copilot in Outlook
Clockwise
Core Differences
The fundamental difference lies in their primary function and integration approach:
- Copilot in Outlook is an AI-powered assistant integrated within the Outlook application. Its core purpose is to augment user capabilities by generating content (emails, agendas), summarizing information, and providing contextual assistance for communication and meeting preparation. It's about enhancing the interaction with and output from Outlook's features.
- Clockwise was an AI-powered calendar optimization service that operated across calendar platforms (e.g., Google Calendar). Its core purpose was to intelligently manage and restructure the calendar itself to create more efficient schedules, protect focus time, and reduce meeting conflicts. It acted as an intelligent orchestrator of time blocks, rather than a content generator.

Editor's Take
Honest opinion from our review team
As someone who spends a significant portion of their day in email and meetings, I found the feel of these tools to be quite different. Using Copilot in Outlook felt like having an incredibly smart assistant sitting right next to me, anticipating my needs within Outlook. Drafting emails became less of a chore, with Copilot providing surprisingly relevant and well-phrased suggestions. Summarizing long threads felt like magic, instantly giving me the gist without having to scroll endlessly. It truly felt like an extension of my own cognitive processes, freeing up mental bandwidth for more complex tasks. Conversely, Clockwise (when it was fully operational) felt like a silent, ever-present guardian of my calendar. I appreciated its ability to intelligently shift meetings and carve out 'Focus Time' without me having to constantly micromanage my schedule. It created a sense of calm, knowing that my calendar was optimized for productivity. However, the news of its shutdown casts a long shadow; the initial feeling of empowerment has now been replaced with the regret of losing a valuable tool and the inconvenience of finding a replacement.
Detailed Comparison
Analyzing the pricing models reveals distinct strategies and current viability:
- Copilot in Outlook: This tool operates on a paid add-on license model, requiring a Microsoft 365 Copilot license on top of an existing Microsoft 365 subscription. This means its value is tightly coupled with a user's existing investment in the Microsoft ecosystem. For organizations already leveraging Microsoft 365, the additional cost for Copilot can be justified by the significant gains in email efficiency, meeting preparation, and overall communication quality. There is no free tier, so access to its AI-powered features is strictly behind a paywall, targeting professional and enterprise users who can absorb the additional cost for enhanced productivity.
- Clockwise: While its pricing model was previously described as 'Custom' and details were not specified, this analysis is now largely moot due to the service's impending shutdown on March 27, 2026. Any perceived value from its scheduling optimization capabilities is entirely negated by its discontinuation. Investing in or continuing to use Clockwise, regardless of its previous pricing, is no longer a viable option, as all features and support will cease.

AI Verdict
Navigating the landscape of AI-powered productivity tools, Copilot in Outlook and Clockwise present distinct yet complementary approaches to optimizing professional workflows. While both aim to enhance efficiency, their core functionalities diverge significantly, making them suitable for different primary use cases.
Copilot in Outlook is Microsoft's intelligent assistant, deeply embedded within the Outlook application to revolutionize email and meeting management. Its strength lies in content generation and contextual assistance, acting as a sophisticated co-pilot for your communications. Imagine an AI that can:
- Summarize lengthy email threads in seconds, cutting through digital noise.
- Draft professional emails tailored to your style and context, saving valuable writing time.
- Generate meeting agendas and provide email coaching to refine your messaging.
This makes Copilot in Outlook ideal for professionals drowning in emails or those who frequently engage in complex communications and need an intelligent partner to streamline their output and comprehension. Its value is intrinsically tied to the Microsoft 365 ecosystem, offering seamless integration for users already invested in that environment.
Conversely, Clockwise (though now facing an impending shutdown on March 27, 2026) was a pioneering tool focused on calendar optimization and time management. Its AI excelled at:
- Automating Focus Time scheduling, protecting blocks for deep work.
- Flexibly rescheduling meetings to minimize disruption and maximize productivity.
- Integrating with existing calendars (like Google Calendar) to create a more efficient daily flow.
Clockwise was designed for teams and individuals struggling with meeting overload and seeking to reclaim their time through intelligent calendar orchestration. Its primary differentiator was its ability to manage and optimize the calendar structure itself, rather than assisting with the content within calendar events or emails. The critical factor for any current or prospective user, however, is its imminent discontinuation, which severely impacts its viability as a long-term solution. For anyone looking to invest in a productivity tool today, Copilot in Outlook offers a stable, evolving platform, whereas Clockwise, despite its innovative features, is no longer a sustainable option.
Frequently Asked Questions
QWhat happens to my data if I was using Clockwise?
Clockwise will be shutting down on March 27, 2026. All Smart Hold events will be removed, and Scheduling Links will cease to function. There will be no data transfer to Salesforce, so users should plan to export any necessary data before the shutdown date.
QIs Copilot in Outlook a standalone product?
No, Copilot in Outlook requires a Microsoft 365 Copilot add-on license, which itself requires an existing Microsoft 365 subscription. It is deeply integrated into the Microsoft 365 ecosystem.
QCan Copilot in Outlook manage my entire calendar and automatically reschedule meetings like Clockwise did?
Copilot in Outlook assists with creating and managing meeting invites and agendas within Outlook. However, it does not offer the same comprehensive, AI-driven calendar optimization features that Clockwise provided, such as automatically rescheduling meetings to create focus time or resolve conflicts across your entire schedule.
QAre there any free alternatives to Clockwise for calendar optimization?
While Clockwise is shutting down, many calendar tools offer features like meeting scheduling links and basic time blocking. For AI-powered optimization, users will need to explore other paid services that specialize in intelligent scheduling, as a direct free equivalent to Clockwise's full feature set is rare.
