Everyone mentions the memory and the voice notes, which are fine, but the thing I keep coming back to is the worlds. Not the single characters - the ones with an actual setting, locations, side characters, a plot that is already moving before you arrive. You do not have to invent a premise or explain where you are standing. You just show up and the scene is already happening around you. Spent most of last week in one of those instead of the one on one chats and it is a completely different experience. Feels more like reading something that reacts to you than messaging a bot. You can poke around without an account if you want to see what I mean - https://honeychat.bot/en/ai-character-chat/
