Designed around one job: safe bulk editing.
Calendar Power Tools focuses on finding the right events, making a controlled transformation, showing the result before anything is written, and keeping a recovery trail.
Powerful filtering
Search by text, date range, event type, recurrence and calendar so you can narrow hundreds or thousands of events to the exact set you need.
Preview before applying
See clear before-and-after values before a bulk write. No blind changes and no guessing what a batch operation will do.
Transaction history & Undo
Keep a recent activity trail and recover supported changes with field-aware Undo and conflict checks.
Your calendar content should stay out of our servers.
Calendar event data is designed to flow directly between the extension and Google Calendar. Calendar Power Tools does not need to store event titles, descriptions, attendees or other calendar contents on its own servers to provide the core product.
We do not sell Google Calendar data or use it for advertising.
Licensing systems can be limited to account, entitlement and payment metadata.
Bulk edits happen only after the user selects events and confirms a preview.
Search → Preview → Apply → Recover
Move dates and times, adjust duration, rename events, update descriptions, locations, availability, visibility, colours, reminders, move calendars, and more—all with a consistent safety workflow.
Calendar Power Tools is preparing for public launch.
We're currently validating reliability, Google OAuth approval, browser-store distribution and paid plans before opening public access.
