Ok. I never tested Instapaper extensively. To collect my articles I still stick with Pocket, but it’s only a question of time until I definitely switch. The search is a disaster, but I love the offline functionality. My preferred tool to replace Pocket would be Refind.
Refind introduced a little different concept. Read later isn’t really great. The collection grows and grows and from read later it becomes read never. Refind steps in at this point. It will grab the article for you when you need it (trought Google or the search inside the tool itself).
