Tabulator is a free Chrome extension developed by Graham Wilson. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. Tabulator aims to help users organize their tabs and save memory while browsing.

With Tabulator, you can convert a window full of tabs into a small group held within the extension. Instead of having multiple tabs cluttering your browser window, Tabulator saves all the links to each website as text URLs within a group. When you want to revisit a specific group of tabs, simply click on the group, and all the tabs will reopen.

One of the key benefits of using Tabulator is its ability to reduce the amount of RAM that Chrome uses. By converting tabs into groups, the extension helps optimize memory usage and improve overall browsing performance. Additionally, Tabulator offers features like grouping a window and its tabs with custom colors and names, reopening groups to restore the window and tabs, and clearing existing groups.

Please note that Tabulator is still being updated to add more functionality, which indicates the developer's commitment to improving the extension's features and user experience. If you're looking for a convenient way to organize your tabs and save memory while browsing, Tabulator is worth considering.
