It’s hard to cope with the loss of a loved one, and it’s harder when their profile pops up on Facebook as a suggestion, as if they were still alive. Now, the social network is using AI to make sure that the profile of the deceased doesn’t “appear in a painful way,” along with some new tools for memorialization for remembering them.

Facebook allows people to memorialize a profile when they pass away, so that they can preserve their memories and make it a place to honor that person. To do that, a person who has been assigned as a legacy contact by the deceased can inform Facebook, or friends and family members can request the social network to memorialize their loved one’s profile by filling out a form and including proof that they’ve passed away.
