knowledge-graph-system vs stashbase
knowledge-graph-system: Kappa Graph is a semantic knowledge graph system designed to extract concepts and relationships from various documents, providing an epistemic layer that measures the reliability and support of claims. It distinguishes itself by offering grounding scores, detecting contradictions, and preserving the full provenance chain to source evidence.; stashbase: StashBase enables AI agents to search and utilize content from your local files, including PDFs, DOCX, images, audio, and video. It creates a searchable index from your folders, allowing agents to find relevant context by meaning rather than just keywords.

Research synthesis and identifying disagreements across papers
stashbaseRAG / Knowledge Base · ★ 1.1k
When to choose:
- You want a desktop app that indexes folders of PDFs, DOCX, images, audio and video and shares them with Claude, Codex and other MCP clients.
- Your files must stay the source of truth: the index can be rebuilt, and removing a folder never deletes files.
- You want exact text search with no key, and semantic search only if you opt in.
When to skip:
- Your documents cannot leave the machine and you need semantic search: it sends content to OpenAI or OpenRouter.
- You are on Linux and need official support: Linux builds are community-supported.
- You only need one file converted now and then: an MCP converter is lighter.
