semantica alternatives
Curated alternatives to semantica — and why you'd switch.
Hyper-Extract
Knowledge-extraction CLI: LLMs turn documents into structured graphs, hypergraphs and spatio-temporal knowledge — with an MCP server for agents and Obsidian vault export.
Why switchBoth LLM-extract knowledge graphs from enterprise sources; hyper-extract stops at extraction with an MCP server, Semantica wraps extraction in governance, analytics and causal reasoning.
Full comparison →omnigraph
Lakehouse graph database for agent context — graph, vector and full-text retrieval fused in one runtime on branchable Lance/S3 storage; agent fleets write on isolated branches and merge Git-style.
Why switchGraph context for agents: omnigraph is a storage-first lakehouse runtime; Semantica is a reasoning-first platform where provenance and causality are the product.
Full comparison →OpenMetadata
Open metadata platform turned AI context layer: 130+ connectors feed a unified knowledge graph of lineage, quality, ownership, glossaries and contracts — served to agents via MCP and APIs.
Why switchEnterprise context layers for AI: OpenMetadata catalogs what data IS across 130+ systems; Semantica reasons over what it MEANS with provenance and causality. Catalog-first vs reasoning-first.
