Your raw files are never uploaded to Locus. When your AI assistant searches, the matching excerpts go to that assistant, as they would if you pasted them in. How each mode works

We have tested it with cited answers in Claude Desktop, Claude Code and Cursor.

What we have tested

No accuracy scores here yet: our early tests ran on one personal vault, too small to generalise from.

How it works

1

Index your files locally

Point Locus at folders on your own machine. It parses, chunks, and embeds your files into a local vector index. Your raw files are never uploaded to Locus. The free local mode is optimized for English; managed mode uses a multilingual model.

2

Connect the AI assistants you use

Locus speaks MCP, the open standard for connecting tools to AI models. We have tested it with cited answers in Claude Desktop, Claude Code and Cursor. The connect guide has setup steps for more, each labelled with how far we have tested it. See the full list

Get cited answers

Ask a question that spans years of notes and documents. Your assistant answers it and points back to the exact files and passages it used.
