The honest version: ChatGPT doesn't natively support the Model Context Protocol that powers Niche King's AI integrations. The native experience, your niche profile, voice samples, face references, brand docs, and 12 AI tools all loaded automatically, works in Claude, Cursor, Windsurf, and other MCP-compatible clients. ChatGPT uses its own Custom GPT Actions system instead.
Why don't we ship a Custom GPT? We chose to focus on the MCP-native experience because it's the only one that loads your full creator brain, niche, voice, face, brand, without per-prompt copy-paste. We'd rather be excellent in the lane that works than market a watered-down version of the experience.
