What is Chub AI?

Chub AI (chub.ai) is a community-driven AI character hub designed for roleplay, storytelling, simulation, and creative experimentation using large language models. Rather than being a standalone AI chatbot like ChatGPT, Chub AI acts as a centralized platform where users can discover, share, and manage AI character profiles that are used with compatible AI frontends and APIs.

Key Features of Chub AI

1. Massive AI Character Library

Chub AI hosts tens of thousands of AI character cards, created and maintained by the community. Each card includes:

• Personality traits

• Speaking style

• Behavioral rules

• Backstory and lore

• Example dialogues

• System prompt logic

This allows users to instantly deploy complex AI personalities without writing prompts from scratch.

2. SFW and NSFW Content Support

Unlike many mainstream AI platforms, Chub AI allows:

• NSFW character profiles

• Adult roleplay scenarios

• Dark or mature storytelling themes

Content is clearly tagged and filtered, giving users full control over what they see.

3. Advanced Tagging & Search System

Chub AI’s discovery system includes:

• Genre tags (fantasy, sci-fi, romance, horror)

• Personality tags (dominant, shy, sarcastic, analytical)

• Content flags (SFW / NSFW)

• Popularity and update-based sorting

This makes it significantly easier to find high-quality, well-tested characters compared to scattered Discord or Reddit repositories.

4. Character Card Customization

Users can:

• Edit existing character cards

• Fork characters and personalize behavior

• Upload private character definitions

• Adjust prompt structure for different AI models

This is ideal for users who want fine-grained control over AI behavior.

5. API & Frontend Compatibility

Chub AI integrates seamlessly with:

• OpenAI-compatible APIs

• Local LLM setups

• Third-party roleplay interfaces

This flexibility makes it model-agnostic, unlike tools locked to a single AI provider.

Characters can be:

• Rated by users

• Reviewed based on realism and consistency

• Improved over time through community feedback

This crowdsourced quality control helps surface the best-performing character prompts.
