ZenToons - Online video filter is a free Chrome extension developed by Damian Suchecki. This add-on falls under the category of Browsers and specifically, Add-ons & Tools. Its main purpose is to prevent overstimulation in children when they are viewing online videos on platforms like YouTube and Netflix.

Intense colors and visually stimulating experiences can have a significant impact on children's behavior. ZenToons offers a solution by allowing users to apply custom filters to online videos, creating a gentler visual experience. This extension offers four different modes to make videos more child-friendly.

The first mode, Natural Colors, reduces vibrant colors for a more soothing viewing experience. The second mode, Low Saturation, further reduces the saturation of colors compared to the Natural Colors profile. The third mode, Night Mode, prepares children for sleep with dimmed and calming colors, while also reducing blue light to promote better sleep. Lastly, the No Filter mode allows users to disable filters when they are not needed.

Using ZenToons is simple. After installing the extension from the Chrome Web Store, users can click on the extension icon in their browser's toolbar. They can then pin the filter to the toolbar for easy access and select their preferred filter mode from the dropdown menu.

One known issue with the extension is that the filter may deactivate after refreshing the page or restarting the browser. However, this can be advantageous, especially if a child shares the computer with an adult.

Overall, ZenToons - Online video filter is a valuable tool for parents and caregivers who want to create a safer and more child-appropriate viewing experience on popular video platforms.
