Semantra is a multipurpose tool for semantically searching documents. Query by meaning, not just match text.

The tool runs on the command line, analyzes specified text and PDF files on your computer, and launches a local web search application to query them interactively. The purpose of Semantra is to make running a specialized semantic search engine easy, friendly, configurable and private/secure.

Semantra is designed for individuals who need to find a needle in a haystack – journalists sifting through leaked documents on a deadline, researchers seeking insights in papers, students engaging with literature by querying topics, historians connecting events in books, etc. wait.
