Octopus.do builds sitemaps: a tree of pages, each page a stack of blocks, each block a wireframe. This connects that to ChatGPT app. Read an existing project — its pages, blocks, and structure — or turn a description or a sketch into a full sitemap: create pages, add blocks with wireframes, move and restructure the tree, all in one batch. Runs through your own octopus.do account over OAuth; the assistant only ever sees projects you already have access to.
