Kokoro

Kokoro is an AI companion app built around anime characters that remember you between conversations. Rather than resetting each session, characters retain what you have told them, develop over time as you keep talking, and can speak their replies aloud rather than only sending text.

Characters are organised by genre, with the maker naming Romance, Fantasy and Supernatural among the categories available, so you choose the kind of story and personality you want to spend time with. The stated goal is relationships that build across many conversations rather than one-off chats - which is why persistent memory and voice are the two features the product leads with.

It is distributed as an Android app and positioned in the messaging and companion space rather than as a productivity assistant. Free to start, per the maker.

One note for evaluation: the public site is a single headline - "Anime AI Characters Who Remember You" - so the detail here comes from the maker's own Product Hunt listing. There is no published feature list, model disclosure, memory-retention policy or pricing page, which matters more than usual for a companion app where you share personal information over time. Worth checking the app store listing for current terms before investing in a character.
