Clockwise vs Smartsheet
A side-by-side editorial comparison of Clockwise and Smartsheet — release velocity, themes, recent moves, and the top alternatives to consider.
Clockwise vs Smartsheet: at a glance
What is Clockwise?
Clockwise shut down on March 27, 2026—data deleted, Reclaim.ai designated as the migration path.
Clockwise has closed. All services ended March 27, 2026; prepaid subscribers receive pro-rated refunds and all user data is scheduled for deletion shortly after that date. The company has formally partnered with Reclaim.ai as the recommended successor for users seeking AI-powered calendar optimization.
What is Smartsheet?
Smartsheet becomes where plans drafted in Claude Sheets get executed.
Smartsheet is rebuilding its core around table view: a table view report builder, Enterprise sheets above 500,000 cells, reports above 1,500,000 rows and a new Gantt view with critical path. On November 10 it added a beta that sends a plan started in Claude Sheets into Smartsheet, ready for a team to act on. Earlier it retired card view for Enterprise and limited AI to Table, Board and Timeline views.
Clockwise vs Smartsheet: editorial side-by-side
Clockwise shut down on March 27, 2026—data deleted, Reclaim.ai designated as the migration path.
◆ Current state
Clockwise has closed. All services ended March 27, 2026; prepaid subscribers receive pro-rated refunds and all user data is scheduled for deletion shortly after that date. The company has formally partnered with Reclaim.ai as the recommended successor for users seeking AI-powered calendar optimization.
◆ Where it's heading
There is no trajectory—the product is in wind-down. The recent changelog entries are shutdown FAQs covering refunds, data deletion, scheduling link deprecation, and the Reclaim migration guide. The formal Reclaim partnership suggests a structured handoff rather than an abrupt closure.
◆ Prediction
The product no longer exists. Reclaim.ai is the designated successor. Any remaining Clockwise calendar events (Focus Time, Smart Holds) were removed from user calendars at shutdown.
Smartsheet
5.0COLLABPM
Smartsheet becomes where plans drafted in Claude Sheets get executed.
◆ Current state
Smartsheet is rebuilding its core around table view: a table view report builder, Enterprise sheets above 500,000 cells, reports above 1,500,000 rows and a new Gantt view with critical path. On November 10 it added a beta that sends a plan started in Claude Sheets into Smartsheet, ready for a team to act on. Earlier it retired card view for Enterprise and limited AI to Table, Board and Timeline views.
◆ Where it's heading
Two tracks are visible. The core product is consolidating onto fewer, larger views, and Smartsheet is positioning itself as the execution layer for work drafted elsewhere, starting with an AI spreadsheet. Imports from SharePoint and Workday sync point the same way: pull data in, run the work in Smartsheet.
◆ Prediction
Expect the Claude Sheets handoff to leave beta and similar send-to paths from other AI assistants, since the release frames Smartsheet as the destination rather than the drafting tool.
