Knowledge Raven: A Searchable Knowledge Base Plugin for Claude

Knowledge Raven is a tool that addresses the limitation of siloed knowledge bases like NotebookLM by creating a searchable repository that Claude can query directly. It eliminates the need to manually copy-paste context between tools.

How It Works

You upload documents or connect to existing sources including Confluence, Notion, Google Drive, Dropbox, and GitHub. The setup process works similar to adding sources in NotebookLM, but allows pulling in hundreds of documents at once through connectors. According to the developer, you can "connect and start with hundreds of documents in minutes."

Once your documents are in Knowledge Raven, you install the Claude Plugin (one click in Claude Desktop) or add the MCP server manually. After installation, Claude can search your knowledge base, explore topics across all documents, and pull up full documents when it needs more depth.

Search Capabilities

The tool provides Claude with three search methods:

• Semantic search for precise questions
• Keyword search for broad exploration
• Full document retrieval as a fallback

The developer describes the difference from dumping files into a Claude Project as: "Claude doesn't get a static blob of text. It gets three search tools and decides itself how deep to dig." They compare it to "handing someone a stack of papers vs giving them a library with a search system."

Practical Implementation

Claude's multi-step search works autonomously. When asked something complex, Claude will typically perform a broad search first to find relevant documents, then a precise search within those results, then pull the full document if needed. Every result links back to the original document in the source system (Confluence, Notion, Drive, etc.) for verification.

The tool also works with ChatGPT via remote MCP server, though the Claude integration is described as smoother due to the Skill in the Plugin.

Availability

Knowledge Raven has a free tier described as "pretty generous for personal use." The developer is looking for 8 beta testers who get full Pro access for free and direct contact with the developer for setup assistance.
