I have used Hope Chest a lot. It is a Chrome Browser extension so only works on Chrome. I am not affiliated with the company other than as a user of the software. It doesn't "scrape" names for temple work like some other products promise, but identifies ancestors who might be ready for temple work. I purchased the pro version when it first came out but the product is now under new ownership who have changed it to an annual subscription model (which I won't do) so I'm back on the limited free version. The free version is fully functional for basic searches, but some features (like saving search results in folders) are turned off - there is a compare page on their web site that shows what each version includes.
I do like it, though, as it helped me find some breakthrough's in my cousin lines. It doesn't do anything you can't already do in FamilySearch, but does help you quickly gather a list of ancestors ready for research rather than combing through ancestral lines one at a time. I went back to ancestors in the early 1800s and searched descendants. It searches through all the siblings so helped me identify lots of cousin lines that had tons of available sources and opportunities for research.
