US Patent 11922345 Task management via a messaging service

A messaging system may receive a plurality of messages in a conversation maintained by a messaging service. It may be determined that a first message sent from a first messaging application associated with a first user comprises information identifying a second user. The messaging system may receive information indicative of a date associated with the first message. At least one database may store an association among at least the first message, the second user, and the date. The messaging system may send information indicative of the date still being active in the at least one database to a second messaging application associated with the second user.
