What you can do
One question pulls evidence from PDFs, Word docs, Excel, PowerPoint, and CSVs — all in a single answer.
Every claim links to its source document, page, and section. Verify anything in seconds.
Find contradictions, missing requirements, and mismatches between documents written by different people at different times.
Drop in a template with placeholders. Locus fills it from your folder — cited, structured, ready for review.
Folder memory means re-opening is instant. Only new or changed files get re-processed.
Documents are indexed on your machine. Only small excerpts are sent securely when you ask a question. Nothing is stored.
Use the built-in model or bring your own API key. Switch providers without re-indexing.
If the answer isn't in your files, Locus says so and stops. No guessing, no hallucinated confidence.
No browser tabs. No cloud accounts. Download, install, point at a folder, and start asking questions.
