An AI mind map generation tool developed by ProcessOn, focused on turning natural language, Markdown, long text, documents, webpages, and text in images into clear, hierarchical, editable professional mind maps with one click. Whether summarizing articles, organizing materials, breaking down documents, consolidating knowledge points, mapping learning paths, or creating reading notes, reviewing academic literature, extracting meeting minutes, summarizing work reports, generating proposal outlines, breaking down project tasks, brainstorming, or exploring ideas, this skill quickly creates professional mind maps to help users turn scattered content into clear, structured knowledge. It supports seven professional layouts: mind maps, logic diagrams, org charts, fishbone diagrams, timelines, tree diagrams, and table diagrams, and is deeply integrated with the ProcessOn online collaboration platform. Generated mind maps can be edited online, collaboratively modified, and reused efficiently, for workplace tasks, study and review, research reading, knowledge management, and proposal planning. Note: This skill is mainly for generating mind maps and knowledge-structure diagrams, not flowcharts, swimlane diagrams, sequence diagrams, system architecture diagrams, ER diagrams, Mermaid diagrams, or other process or technical diagrams.
Design, build, refactor, or review terminal interfaces—full-screen TUIs, interactive prompts, and command-line tools. Use for terminal-app layout and UX, CLI behavior, ncurses-style tools, dashboards, REPLs, fzf-like pickers, and libraries such as Bubble Tea, Ratatui, Textual, or Ink, including requests that name a known TUI such as lazygit, k9s, btop, helix, or yazi instead of saying “TUI.” Do not use for browser or web UI, native GUI, editor or font configuration, or backend and shell work that has no terminal interface
