Semantica

A code library that organises company data into a connected map of facts that AI agents can use and explain.

New this week

What it does

Semantica is a Python library for building a knowledge graph, a map of things and how they relate to each other, from a company's own data. AI agents can then use this map as context instead of relying only on loose text matches.

Its makers say it also keeps a record of where each piece of information came from and how a decision was reached. They describe this as useful in regulated fields where people may need to explain why an AI system gave a certain answer.

An AI language model is optional. The README says it works with many providers, including OpenAI, Anthropic and Gemini.

Who it's for

Data and AI teams at companies who need structured, traceable context for their AI agents.
