VoidStack - 4D Knowledge Stack & Graph to Structure Your Thoughts A knowledge management tool highly recommended as a memo pad for your AI chat sidebar or for organizing your thoughts. Instantly accumulate information and fragments of thoughts from the web, and visually structure them using a 4D graph (Network, Kanban, Timeline, etc.). It functions as a local knowledge base equipped with automatic organization via Chrome Built-in AI and seamless export to Obsidian. VoidStack temporarily stores ideas and collected information while browsing, visually organizing and connecting them using an advanced graph system. The accumulated data is managed in Markdown format and can be instantly exported to local apps like Obsidian. ■ Key Features Quick Capture & Multi-functional Editor Instantly create notes by selecting text on the web and right-clicking, or directly from the dedicated panel. Supports drag-and-drop for images and direct input from the clipboard. Features a full-screen "Zen Editor" for focused writing, supporting real-time Markdown preview. 4D Graph Visualization Seamlessly switch between the following 5 modes to overview and edit your accumulated notes: 🕸️ Network: A dynamic node correlation map using physics simulation. 🧠 Mindmap: A mind map that visualizes hierarchical structures. 🧊 3D Space: A 3D view that arranges information spatially. 📋 Kanban: Column-based categorization based on assigned tags (hashes). ⏳ Timeline: Chronological display based on note creation and ordering. On-Device AI Information Refinement (Chrome Built-in AI) Automatic note summarization and smart tag (hash) suggestions. Logical merging of multiple notes. *This feature runs entirely on your local device, ensuring absolutely no data is sent to external servers. Powerful External Integration (Obsidian Support) One-click transfer of individual notes as new Obsidian notes via URI scheme (obsidian://). Bulk export your entire dataset as a set of Markdown files to a local folder, retaining attached images and link relationships (Wiki link format). ■ Recommended Workflow: High-Speed Thought Organization via AI Chat Integration By docking VoidStack to the right sidebar alongside AI chats like ChatGPT or Claude, you can achieve highly efficient knowledge processing. The following steps are the best practice for quickly organizing complex concepts: Copy and paste the AI chat output into VoidStack's main panel to create a note. Use prompt buttons like "Map" at the bottom of the panel to instruct the AI to generate structured output following VoidStack's specific Markdown rules. Right-click the structured note and execute "✂️ Split Note". The text will automatically expand into individual nodes with logical parent-child relationships. Open the graph panel using the "[Graph]" button at the top, and visually overview and rearrange the expanded nodes to finalize your thoughts. ■ Target Audience Researchers, writers, and engineers who rely heavily on web research. Users of Zettelkasten-style note-taking apps like Obsidian. Anyone looking to visually map and organize scattered ideas. Those who want to visualize and organize AI conversation results as logical nodes. ⚠️ Important Notice Regarding AI Features VoidStack's AI features (summarization, tag generation, etc.) utilize Chrome's experimental built-in AI model (Gemini Nano). To use these features, you must enable the corresponding Chrome Flags via the following steps: Enter chrome://flags/#prompt-api-for-extension into your address bar. Change the setting to "Enabled" and restart your browser. *Even if not enabled, all other features (note creation, graph visualization, exporting, etc.) will function perfectly. 🔒 Privacy and Required Permissions VoidStack is completely designed with a local-first approach. Your note data and images are never sent to external cloud servers (AI processing is also completed entirely on-device). This extension requires the following permissions: storage: To securely save your note data and settings to the browser's local storage. clipboardRead / clipboardWrite: To provide text input to the panel and bulk copy functionality for your accumulated notes. scripting / activeTab: To inject the operation panel onto the current page only when you select "Add to VoidStack" from the context menu or click the extension icon.
