Frequently Asked Questions

Does it work on YouTube, Netflix and other sites?
It supports most HTML5 videos. Some DRM-protected players (e.g., Netflix) may restrict speed or screenshots due to site policies.
Will changing speed affect audio pitch?
No. The controller preserves pitch while changing speed, so speech remains natural and intelligible.
How can I set a precise custom speed like 1.75x?
Use the number input for exact values (e.g., 1.25, 1.75, 2.25). Preset buttons 1x/1.5x/2x/4x/8x are also available.
Where are screenshots stored? Is my data uploaded?
Screenshots remain locally in your browser. No tracking, no upload. You can right‑click to save the image.
The controller doesn’t show up on some sites. What can I do?
Refresh the page, ensure the video is HTML5, and disable conflicting extensions or site-specific speed features.
Is it compatible with other video extensions?
Yes in most cases. If you encounter conflicts, temporarily disable other video-related extensions.
