SimpleMind ChatGPT Extension is a custom GPT by One App Company that helps users create SimpleMind mind map files directly from a conversation. It can turn ideas, notes, and structured content into SimpleMind-compatible files, generate an instant preview, and make the first version of a mind map much faster.With SimpleMind Pro, the generated files can also be opened and edited further, turning the extension into a bridge between AI-assisted thinking and a real mind-mapping workflow.
