The short version

By ClawHub Community

Build a persistent knowledge base that gets smarter every time you add a source or ask a question.

By Steph Ango (Kepano / Obsidian)

Write powerful notes in Obsidian with linked pages, embeds, callouts, and rich formatting.

Reads your sources and creates structured markdown wiki pages with summaries, key facts, and cross-references
Updates existing pages when new sources add information, and flags contradictions between sources
Answers questions by synthesizing across your wiki pages with inline citations
Runs health checks to find contradictions, orphaned pages, missing cross-references, and gaps in your knowledge base
Maintains a master index and operation log so you always know what's in your wiki and how it evolved

Links notes together automatically so you can build a connected knowledge graph
Embeds content from other notes, images, PDFs, and files directly into your current note
Creates highlighted callouts for warnings, tips, questions, and important information
Organizes notes with tags, properties, and frontmatter for easy searching and filtering
Formats notes with highlighting, footnotes, math equations, and diagrams

You're researching a topic over weeks or months and want to compound your learning instead of re-reading
You need to track information from multiple sources and spot where they agree or contradict
You're building expertise in a domain and want a searchable, structured knowledge base that grows with you
You want your AI to remember what you've already processed and build on it, not start from scratch each time

You're building a personal knowledge base or second brain in Obsidian
You need to organize project notes, meeting notes, or research with interconnected links
You want to create rich documentation with embedded images, PDFs, and cross-references
You're managing a team wiki or shared knowledge repository
