Chub AI
What Chub AI is
Chub AI is a paid platform for interacting with characters through AI large language models connected through APIs. It runs on web, Android, and iOS. The service lists integrations for OpenAI, Mars, Anthropic, Kobold/Ooba, OpenRouter, Google, and NovelAI. OpenAI and Anthropic connections can use an API key or reverse proxy, while the guide recommends official keys for security and reliability. Kobold/Ooba can connect to models hosted on your own machine, with hardware requirements as the limitation. Chats support branching, image generation, and importing or exporting. Export formats include JSONL for SillyTavern, PNG, and text files. Lorebooks attach defined information to chats when keywords match, controlled by scan-depth and token-budget settings. Optional Stages can add expression packs, mini-game interfaces, prompt handling, or third-party API interactions. Chub describes its content policy as uncensored. The Mars plan costs $20 a month and includes unlimited messaging.
