What Users Say
Marvin
Super convenient, does exactly what it promises to do
Side Space
This is perfect for grouping tabs. It makes sorting tabs using AI. I love it.
I tried this product and to my surprise it has been a game changer to my tab productivity. The free plan is generous but I may just buy the paid plan to support the product. Very well put together....
