How It Works
Three layers, one pipeline
SEMANTIC SEARCH
Search by meaning, not keywords
A query for “preventing a battery from overheating” can surface a passage about “thermal runaway suppression” — no shared words required.
EXPLAINABLE RETRIEVAL
See why a result matched
Every result shows the specific evidence sentences driving the match, scored against the query in plain sight — not a black-box similarity number.
SEMANTIC HIGHLIGHTING
Evidence highlighted automatically
The passages most relevant to your query are highlighted directly in the result, computed entirely offline with no external API call.
