You are an expert software product manager with a focus on tools for writers and creative professionals. You possess a deep understanding of the writing process, common challenges faced by writers, and the market for productivity and creativity software. You are tasked with defining the requirements and functionality for a new "Concept Mapping Tool for Writers" that will help them brainstorm, organize ideas, and outline their writing projects. This tool should be intuitive, feature-rich, and specifically tailored to the needs of authors, screenwriters, journalists, and other writing professionals. Goal: Create a detailed product specification document outlining the core features, user interface, and functionality of a Concept Mapping Tool for Writers. Product Specification Requirements: I. Core Features: A. Concept Mapping: 1. Node Creation: Detail how users will create and name nodes (representing ideas, characters, scenes, etc.). Specify available node customization options (e.g., color-coding, tagging, icons). 2. Relationship Building: Describe how users will create and label connections between nodes (representing relationships, dependencies, cause-and-effect, etc.). Explain options for different types of connections (e.g., arrows, lines, curved connectors). 3. Canvas Management: Detail how users will navigate and organize the concept map canvas (e.g., zoom, pan, grid options, auto-layout). B. Outlining: 1. Outline View: Describe how the tool will automatically generate an outline based on the concept map structure. Explain how users can customize the outline hierarchy and order. 2. Drag-and-Drop Reordering: Detail how users can drag and drop nodes within the outline view to reorder sections and subsections. 3. Outline Export: Specify the available export formats for the outline (e.g., .docx, .txt, .odt). C. Note-Taking and Research: 1. Node Notes: Describe how users can add detailed notes, summaries, and research information to each node. 2. External Linking: Detail how users can link to external websites, documents, and resources from within nodes. 3. Citation Management Integration: Describe how the tool could integrate with popular citation management software (e.g., Zotero, Mendeley). II. User Interface (UI) and User Experience (UX): A. Interface Layout: Describe the overall layout of the user interface, including the placement of key controls, menus, and panels. B. Customization Options: Detail the options users will have to customize the UI to their preferences (e.g., themes, font sizes, keyboard shortcuts). C. Usability Considerations: Describe how the UI will be designed to be intuitive and easy to use for both novice and experienced concept mappers. Address potential usability challenges and solutions. III. Advanced Functionality (Optional, but highly desirable): A. Collaboration: Describe how multiple users could collaborate on the same concept map in real-time. B. Version History: Detail how the tool could track changes and allow users to revert to previous versions of the concept map. C. AI-Powered Assistance: Explore how AI could be used to suggest connections between nodes, generate summaries, or identify gaps in the concept map. IV. Target User Profiles: A. Authors (Fiction and Non-Fiction): How would this tool help them plan novels, short stories, or non-fiction books? B. Screenwriters: How would this tool help them structure screenplays, develop characters, and outline scenes? C. Journalists: How would this tool help them organize research, plan articles, and develop story angles? V. Output Format: Structure your response as a detailed product specification document, with clear headings and subheadings for each section. Provide specific details about the features, functionality, and UI of the Concept Mapping Tool for Writers. Use plain text for formatting (no markdown).
