Locus AI

Ask your documents. Verify every answer.

Locus AI is a desktop app for working through large sets of documents. Drag in PDFs and images, ask questions in plain English, and get answers with inline citations that highlight the exact supporting text on the source page.

What it does

Answers you can check, not just trust

AI answers are only useful in serious work if you can verify them. Locus AI is built around that one idea: every claim points back to its source.

Citations on every answer

Answers carry inline numbered citations tied to specific source pages, so each claim can be traced and checked.

See the exact source

Click a citation and the source page opens with the supporting text highlighted, right where it appears in the document.

Reads scanned documents

Image-only PDFs and photos are read with AI vision, so old scans and pictures are searchable and citable too.

Flags conflicts

When your documents disagree with each other, Locus AI points it out instead of quietly picking one side.

Your library, on your machine

Your document library is stored on your own machine, and the built-in document search runs entirely locally, instantly and at no cost. AI answers and the reading of scans and photos use a cloud AI model.

Built for big document sets

Even huge document libraries stay quick to search and ask, and long research threads are managed so the conversation can keep going.

Who it’s for

For work where a wrong answer costs you
