Product Philosophy

+ +
+

+ The interface design is guided by five core philosophical principles that dictate every aspect of the user experience. +

+ + +
+

+ + Workspace-First Architecture +

+ +
+

+ Every element of content—pages, folders, tags, and team members—exists within an isolated + workspace. Switching workspaces is not a filter but a complete context switch into a new + content universe. This architecture prevents cognitive overload and maintains strict separation + between different projects or life domains. + [1] +

+
+ +
+

Workspace Context Model

+ +
Project Alpha
+
+
+ +
Personal Notes
+
+
+ +
Client Work
+
+
+

+ Each workspace operates as a completely isolated environment with its own content universe. +

+
+
+ + +
+

+ + Bi-Axial Organization System +

+ +
+

+ Content is organized through two complementary systems: hierarchical folders for + structured navigation and flat tags for cross-cutting discovery. This dual approach + balances rigid organization with flexible, contextual discovery. + [2] +

+

+ + Search-First Navigation +

+ +
+

+ The interface prioritizes search over manual navigation. A prominent search bar with persistent + filter chips provides immediate feedback on the current context, making information retrieval + the primary interaction model. + [3] +

Accessibility & Usability

+ +
+
+

WCAG 2.1 AA Compliance

+ +
+
+

+ + Sufficient Color Contrast +

+

+ All text maintains 4.5:1 contrast ratio against backgrounds, + ensuring readability for users with low vision. +

+
+
+ 4.5:1 +
+
+ 4.5:1 +
+
+
+ +
+

+ + Visible Focus Indicators +

+

+ Interactive elements display clear focus states for keyboard navigation, + supporting users who don't use pointing devices. +

+
+ + +
+
+ +
+

+ + Zoom Compatibility +

+

+ Layout remains functional and readable at up to 200% zoom, + reflowing content to avoid horizontal scrolling. +

+
+
+
+ +
+

Touch Accessibility

+ +
+
+

+ + Minimum Touch Target +

+

+ All interactive elements maintain minimum 44×44px touch targets + for accurate tapping on mobile devices. +

+
+
+ 44px +
+
+
+ +
+

+ + Descriptive ARIA Labels +

+

+ Icon buttons include descriptive aria-label attributes for screen reader users, + ensuring all functionality is accessible to users with visual impairments. +

+
+ +
+

+ + Cognitive Load Reduction +

+

+ Rarely used options are hidden behind hover-reveal patterns, + while common actions remain always visible to reduce cognitive overhead. +

+
+
+
+
+
+
+ + +
+
+

The Implicit UX Story

+ +

+ The interface tells users an implicit story about how to work effectively with their knowledge. +

+ +
+ +
+
+
+ +
+

1. Find

+

+ Start with search, refine with folder/tag filters. + The interface makes this the most prominent action. +

+
+ +
+
+ +
+

2. Browse

+

+ Use the central index as a dashboard when exploring + folders, with dates and snippets providing context. +

+
+ +
+
+ +
+

3. Edit

+

+ Enrich content in the right panel with tags, bookmarks, + and attachments. The toolbar provides all tools in context. +

+
+ +
+
+ +
+

4. Diffuse

+

+ Share directly or publish to branded portals. + The transition from private to public is seamless. +

+
+
+ + +
+

The Continuum of Experience

+ +
+
+
+ +
+
Writing
+
+
+
+
+ +
+
Publishing
+
+
+ +

+ The omnipresent "Add to portal" and "Share" buttons create a natural continuum + between creation and dissemination, treating publishing as a natural extension of writing. +

+
+
+
+
+ +
+ + +
+
+
