knowledge-graph-system vs obsidian-everywhere

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.; obsidian-everywhere: Obsidian Everywhere transforms Obsidian notes into a structured graph and semantic knowledge base, providing token-budgeted AI context for remote agents. It integrates safe editing, optional local semantic search, and Git-backed version control, ensuring data integrity while keeping your vault on your local machine.

Features

knowledge-graph-system logoknowledge-graph-system
01Ingest documents (PDFs, markdown, images, text)
02Search by meaning, not just keywords
03Check confidence with grounding scores and detect contradictions
04Trace claims and concepts back to original source evidence
05Query via AI assistants through MCP server integration
obsidian-everywhere logoobsidian-everywhere
01Graph + semantic context engine: Parses markdown, indexes with SQLite FTS5, and uses in-memory graphology for rich graph traversal and token-budgeted context bundles.
02Remote Vault Bridge: Exposes graph and guarded write tools over authenticated Streamable HTTP, allowing external agents to access and modify your local vault securely.
03Optional local semantic search: Runs a multilingual embedding model entirely on your machine for meaning-based search, without requiring external API keys or cloud services.
04Safe writes and resilient mounts: Features partial edits, dry-run bulk operations, rollback snapshots, recoverable deletion, and a Beta mount guard for data integrity.
05Reviewable Git checkpoints: Allows agents to inspect repository status, bounded diffs, and local history, with commits and pushes requiring explicit preview and one-use approval IDs.
