Overview

Chub AI (originating from the merger of CharacterHub and Venus AI) is an open, model-agnostic platform dedicated to AI character creation, roleplay, and interactive fiction. It serves as both a community repository for tens of thousands of portable "character cards" and an interactive web chat frontend. Unlike walled-garden alternatives, Chub AI acts as a flexible routing layer. Users can chat directly on the platform by connecting their own API keys (OpenAI, Anthropic Claude, OpenRouter, or local backends) or utilize Chub’s subscription-based hosted models. ### Key Capabilities & Features * **Portable Character Cards:** Complete compatibility with standard AI tavern card formats (PNG/JSON metadata containing lorebooks, personality prompts, and scenario triggers) for easy export to tools like SillyTavern. * **BYOK Architecture:** Full support for Bring-Your-Own-Key, allowing creators to power complex roleplay scenarios using frontier models without arbitrary platform censorship. * **Deep Persona Configuration:** Granular control over conversation context size, memory management, chat branching/trees, and custom token generation parameters. * **Lorebooks & World-Building:** Integrated world info modules that dynamically inject relevant narrative context and lore entries as conversations progress. ### Best Used For Long-form interactive storytelling, unconstrained character roleplay, testing conversational system prompts, and sourcing interoperable character cards for local LLM frontends.
