Focus Snail is a free Chrome add-on developed by Nikita Vasilyev. It falls under the category of Browsers and specifically belongs to the subcategory of Add-ons & Tools. This add-on is designed to leave a trail from the previously focused element, providing a visual indication of the user's navigation path.

With Focus Snail, users can easily keep track of their focus movement on web pages. The add-on creates a visual trail, resembling a snail's path, highlighting the elements that were previously focused. This can be particularly useful for users who navigate through complex web interfaces or struggle with attention span.

The simplicity of Focus Snail's concept is what makes it stand out. By leaving a visual trail, it helps users stay oriented and easily retrace their steps. Whether you're conducting research, filling out forms, or just exploring the web, Focus Snail can enhance your browsing experience by providing a clear visual indication of your focus history.

Please note that Focus Snail is an experimental user interface (UI) experiment. If you're interested in trying out unique browsing add-ons, you can find it on the Chrome Web Store.
