The Bottom Line Verdict
ClayCodes was the trailblazer for Google Slides timers, but its reliance on browser reloads, fragile audio triggers, and undocumented symbols makes it showing its age. Live Slides Timer delivers a modernized, frustration-free experience with reliable built-in sound, instant tab activation, and an interactive builder.
The Evolution of Google Slides Timers
For years, the Chrome extension created by Clay Smith (ClayCodes) was the default choice for educators wanting countdowns in Google Slides. However, modern presentation demands have grown, and users frequently encounter friction with older extensions.
Key Differences
1. Works Instantly After Install
With ClayCodes, users are repeatedly greeted with the warning: 'Be sure to refresh your slides after you install for the timer to work.' If you are already in a live presentation or running on a borrowed conference computer, closing and reloading tabs is stressful.
Live Slides Timer injects dynamic listeners immediately. You install it, hit Present, and it works on your existing presentation without touching reload.
2. Built-in Audio That Actually Works
Playing audio when time runs out with ClayCodes historically required inserting a hidden YouTube video or audio element on the slide with complex triggers like -@ that frequently get blocked by Chrome's autoplay policies.
Live Slides Timer includes a bundled, local high-fidelity acoustic bell chime that plays directly via the Web Audio API without needing external media files on the slide.
3. Visual Floating Builder vs Memory Gymnastics
Instead of forcing you to memorize whether -+ means advance or -- means reverse, Live Slides Timer gives you an intuitive floating wand button inside Google Slides. Pick your minutes, toggle sound on, and insert.
