ChatGPT plugins

Every Cybrix.AI custom GPT, rebuilt as a ChatGPT plugin: an MCP server with real tools, so diagrams, slides, sheet music and charts appear right in the chat. Plus a few new ones.

// why the change

OpenAI is retiring custom GPTs on December 11, 2026 (32 days from now) and replacing them with plugins. Until then every classic GPT below keeps working. When a plugin goes live you can add it from the ChatGPT Plugins directory, then start a chat with @ and its name. Need the same for your own GPT? See GPT migration.
