knowledge-graph-system vs omniseek

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.; omniseek: OmniSeek is a self-hosted perception server that extends AI agents' ability to find information beyond conventional search engines. It can process data from diverse, complex sources like podcasts, login-walled forums, and cross-lingual content by hearing, seeing, and remembering information locally.
