You pick from a large catalogue of AI companions or design your own, then hold open-ended conversations that unfold as roleplay, romance, fantasy adventure, or whatever premise the character carries. Creating a character means defining more than a name and an avatar. You set personality traits, background, a scenario that frames the first meeting, and a greeting message that shapes the tone of the conversation. CAVEDUCK also offers World and Scenario frameworks so characters can share a common setting, which makes multi-character storytelling and consistent worldbuilding possible. Discovery is a big part of the experience. The home feed surfaces featured, recent, trending, and popular characters alongside curated picks from official creators and rising talent, and tags help you find a specific vibe quickly. A Store provides premium characters, subscriptions, and credit options on top of the free experience. CAVEDUCK hosts mature roleplay categories with age-gating and published terms, and operates from a registered US address with support and policy pages for privacy, refunds, and DMCA complaints. **Pricing & Plans:** CAVEDUCK follows a freemium model with a free trial.

It frames AI chat as story-driven roleplay: you pick or create a character, set the scene, and the character keeps responding in role while the plot moves forward. The design emphasis is on long, continuous narratives rather than disposable conversations. Memory is a core selling point. Characters retain details from earlier sessions and keep notes you can review, which makes multi-week storylines possible. Replies are written with actions, feelings and dialogue so the text reads like prose, and at story moments you get to choose what happens next. You can also switch between well-known AI models to change the writing style. Beyond chat, Rubii bundles creation tools. You can build an original character with a detailed setting, generate its portrait and short videos, and publish it for the community. Everything lives under one account that works on the web, iPhone and Android. Rubii is operated by Perchy, LLC and is free to start, with a paid tier that unlocks premium features such as editable memory notes. **Pricing & Plans:** Freemium. Browsing public characters and starting chats is free, and premium features such as editable memory notes and enhanced capabilities come with the paid Rubii+ subscription. In-app currency (Rubies) is also used for certain creative actions, and creators can earn a share of Rubies for published characters. - **Long-term character memory:** Characters bring up details you shared weeks earlier, and you can review their memory notes so long stories stay consistent. - **Novel-style responses:** Replies include actions, feelings and dialogue, turning a chat into something closer to reading a novel. - **Branching story control:** At key story moments you choose what happens next and watch the scene change with your decision. - **Character and art creation tools:** Write a detailed character sheet, generate its portrait and short videos, then publish it so others can chat with it. - **Multiple AI model choices:** Switch between top models such as Claude and Gemini to find the writing style you prefer. - **Built-in image and video generation:** Generate character art and short videos for your stories directly inside the chat and creation workspace. **Strengths:** Free to start with a large library of community characters; Strong long-term memory for continuing storylines; Combines chat, character creation, images and video in one workspace; Choice of multiple leading AI models for writing style **Limitations:** Long-memory and premium model options are gated behind the paid tier; Best experience with original characters assumes some creative writing effort; Quality of community-made characters varies; Image and video generation may consume additional in-app currency [Profile (Markdown)](https://openaitools.app/tool/rubii.md) ## Frequently Asked Questions ### How do CAVEDUCK and Rubii compare in monthly traffic?
