Spaces — overview of all knowledge spaces with page counts and recent activity
Features
Documentation That Doesn't Suck
A team wiki built for engineers who actually need to find things. Hierarchical pages, version history, wiki-links, templates, and full-text search — all backed by 93 MCP tools so your AI assistant can read and write documentation alongside you.
Organization
Spaces, Pages, and Structure
Spaces
Top-level organizational units for teams, projects, or knowledge areas. Each space has its own page tree, permissions, and settings. Like Confluence spaces, but faster.
Hierarchical Pages
Markdown documents with parent/child relationships. Unlimited nesting depth. Drag-and-drop reordering in the sidebar tree. Breadcrumb navigation at every level.
Wiki-Links
Cross-reference pages with [[Page Title]] or [[SPACE:Page Title]] syntax. Backlinks tracked automatically. Broken link detection built in.
Templates
Reusable page skeletons for consistent documentation. Meeting notes, design docs, runbooks, ADRs — create the template once, stamp out pages that all look right.
Authoring
Write in Markdown, Render Beautifully
Markdown Native
Write in standard Markdown with extensions for tables, code blocks with syntax highlighting, task lists, and admonitions. No proprietary format lock-in.
Version History
Every edit creates a versioned snapshot. Side-by-side diff view between any two versions. Restore previous versions with one click. Full audit trail of who changed what.
Full-Text Search
Instant search across all spaces and pages. PostgreSQL full-text search with ranking, highlights, and filters by space, author, or date range.
Dark Mode
Full light and dark theme support. Respects system preference with manual override. Syntax highlighting adapts to theme. Easy on the eyes at 2 AM.
AI Integration
93 MCP Tools
AI-Powered Content
93 MCP tools let Claude create, search, update, and manage wiki content directly. Draft documentation, update pages, and organize knowledge without leaving the conversation.
Cross-Tool Integrations
Connected to the full Renkara tool fleet. Narrative for publishing, Docket for issues, Herald for newsletters, Beacon for SEO, Pulse for analytics, Meridian for time, Tribe for contacts, Cadence for calendar, and Vigil for health monitoring.
Accessibility
Built for Everyone
WCAG 2.1 AA Compliance
4.5:1 contrast for body text, 3:1 for large text and UI components, in both light and dark themes.
Keyboard Navigation
Every interaction reachable via keyboard. Logical tab order, visible focus indicators, Escape-to-dismiss for modals.
Screen Reader Support
VoiceOver, NVDA, and JAWS tested. Semantic HTML, ARIA labels, live regions for dynamic updates.
Reduced Motion
Respects prefers-reduced-motion. Usable at 200% zoom. Touch targets meet 44x44 minimum.
How It Works
From Thought to Documentation
Create a Space
Set up a space for your team, project, or knowledge area. Configure permissions and defaults.
Write Pages
Author in Markdown with wiki-links, code blocks, and tables. Use templates for consistent structure. AI can draft content via MCP tools.
Organize
Build page hierarchies with drag-and-drop. Cross-reference with wiki-links. Backlinks keep everything connected.
Find
Full-text search across every space and page. Filter by space, author, or date. Your team's knowledge is always one search away.
