Global shortcut (Shift+Cmd+J) for distraction-free quick notes. Professional Markdown editor with math formulas, Mermaid diagrams, and code highlighting.
Project (Overview) β Theme (Insights) β Note (Atomic). Mimics academic book structure, not flat folders.
Index-style dual-link system with O(1) lookup. Co-occurrence matrix analysis reveals hidden relationship patterns in your knowledge network.
Canvas mode with drag-drop card organization. 6 post-it colors, Theme grouping borders - transform fragments into visual insights.
AI assists with summarization, not thinking replacement. Handles tedious formatting and note organization suggestions, keeping you in control of your thoughts. Rejects the false productivity of "AI delegation".
Notion AI and ChatGPT create an illusion of "efficiency", but generated content lacks your thinking fingerprint. True insights only crystallize through hands-on organization.
AI only for auxiliary scenarios: smart tag suggestions, note summarization, related note recommendations. Core thinking stays under your control - AI is just a smart assistant.
Index-Style Dual-Link: Mimics academic book indexes, O(1) lookup, clear
citation relationships.
Co-occurrence Matrix: Reveals hidden
relationship patterns between nodes, discovering "frequently co-occurring" theme clusters.
Obsidian/Roam's spider-web graphs look cool but provide little actionable insight. Researchers need clear indexes like paper footnotes, consultants need data-driven relationship analysis.
Dual-Link: Dictionary index + auto-sync, supports million-scale
nodes.
Co-occurrence: Matrix math calculates co-occurrence frequency,
heatmap shows relationship strength, auto-clustering reveals hidden themes.
Treat notes as cards on an infinite canvas - freely drag, group, and connect. 6 post-it colors, Theme grouping borders, simulating the physical feel of real brainstorming.
Lists and folders are linear, unable to represent three-dimensional knowledge relationships. Through spatial positioning, color grouping, and connection lines, fragmented knowledge relationships come alive, elevating your thinking across different levels.
Manually drag cards with grid auto-alignment. Theme notes auto-generate dashed borders surrounding child cards. Supports color grouping, auto-layout, collision detection, selected card elevation.
Beyond single-note export - project-level book-quality typesetting. Auto-generates TOC, cover page, chapter pagination, dual-link index afterword, reaching publication-grade quality.
Academic papers, consulting reports, product documentation need formal delivery. Notion exports are rough, Obsidian lacks structured typesetting - unsuitable for professional scenarios.
Single-note: Complete Markdown rendering, math formula images, pagination
layout (β
complete).
Project-level: TOC generation, cover page, chapter
layout, index afterword (π§ in development).
