semantica
by semantica-agi
Semantica is a Python library that turns company data into a knowledge graph, with a record of where each fact came from and how each decision was reached. It sits underneath an AI agent or language model to give it structured context and an audit trail.

What you can do with it
- Build a knowledge graph from messy, multi-source business data, with conflicting facts flagged and duplicates merged
- Record every AI decision with its provenance so you can explain later why it was made
- Define rules and vocabularies (OWL, SHACL, SKOS) and run reasoning and SPARQL queries over your data
Make money with it
A freelance developer could offer to build governed knowledge graphs and audit-ready AI assistants for small firms in regulated fields such as finance or legal.
An idea, not financial advice. Check the licence before charging for anything built on it.
Ways a business could use it
- Give a customer-facing AI assistant a structured, queryable memory of products, policies and past decisions instead of relying on similarity search alone
- Keep an audit trail of automated decisions to support compliance checks without buying an enterprise governance platform
Can you use it commercially?
Free to use, change and sell, including in paid products. Keep the copyright notice.
Not legal advice. Read the project's licence file before building a product on it.
Getting it running
Install it as a Python package with "pip install semantica", then use it in your own code or through its command-line tool.
Follow the official instructions in the project README.
Things to check
- Aimed at developers and needs programming knowledge and graph concepts to use well
- Some features rely on an optional LLM, which may need paid API keys
- Does not explain what happens inside the language model itself, only the context around it
