Rubii

Rubii is a free-to-start AI character chat and roleplay platform with editable long-term memory, choose-your-own story moments, model switching and built-in image and video tools for creating and publishing original characters.

Rubii is an AI character chat and roleplay platform built around long, story-driven conversations instead of short one-line replies. Users browse a library of community-made characters, pick a genre such as fantasy adventure, sci-fi, anime, wholesome comfort or romance, and play out a scene with a character that stays in role. Replies combine actions, feelings and dialogue, so a session reads closer to a serialized novel than a chatbot exchange. The tool is aimed at roleplay fans, interactive fiction readers and hobbyist creators. Memory is a central feature: characters recall details from earlier chats, and the memory notes they keep can be opened and edited, which gives users direct control over continuity. Story moments let the user choose what happens next and watch the scene change. Users can also switch between top language models, including Claude and Gemini, to find a writing style they prefer, and give each character a custom chat look, from cosy diary layouts to neon game screens. Creation sits alongside chatting. A creator writes a character with a detailed setting, generates a portrait and short videos with the built-in image and video tools, then publishes it so others can chat with it. The site also describes a creator rewards program paid in in-app currency, and community channels on Discord, Reddit and other networks. In practice, a user starts on the web, enters the explore page, opens a character and sets the scene by saying who they are and where the story begins. The same account carries over to iPhone and Android apps, so a chat started on a laptop continues on a phone. Entry is free, with public characters browsable before any purchase. Among alternatives, Rubii positions itself directly against Character AI, emphasizing no ads, no slow mode and creator payouts, and it competes with other companion and roleplay chat apps on memory depth, model choice and bundled media generation.
