A FamilySearch account is required to sign in.
After you sign in, you can research from FamilySearch Tree or from an Ancestry tree. That is, you need to choose a person from either tree as the basis for your research.
The research log can log any page on the Internet, including records from FamilySearch, Ancestry, MyHeritage, Findmypast, Findagrave, BillionGraves, Google, etc.
Automatic citations are created for FamilySearch and Ancestry records.
The locality features include place-specific links to the catalogs of FamilySearch, Ancestry, MyHeritage, and WorldCat.
Over time, these features will be expanded to include more services.
