Chub AI (also known as CharacterHub) is an AI companion and roleplay platform built around character cards, lorebooks and scenarios that users can discover, create and share. Its chat interface, Venus, integrates various language models and supports uncensored, open-ended roleplay.
The platform is popular with writers, roleplayers and creators who want deep narrative control, including reusable character definitions, world-building lorebooks and shareable scenarios. It functions both as a community repository of characters and as a chat front end for interacting with them.
Chub AI markets itself around creative freedom and minimal content restriction, differentiating from mainstream assistants by catering to mature roleplay and detailed character authorship. It has a sizable and active community with substantial monthly traffic.
The service operates on a freemium model, with free access plus paid tiers for enhanced model access and features. There is no publicly disclosed venture funding or named founding team, in line with the broader bootstrapped companion segment.
