Capabilities

Every file converges
to one point of clarity

Locus reads your documents, indexes them locally, and grounds every answer in the actual source. No guesswork.

Every answer has a source

Every answer traces back to your actual documents — file name, page number, exact section. If Locus can't find it in your files, it won't make it up.

Every office format

PDFs, Word docs, Excel spreadsheets, PowerPoint decks, CSVs, and plain text — all readable, all searchable, all in one place.

Files stay on your machine

Your documents never leave your computer. Only small text snippets are sent to get your answer. Nothing is stored.

Spot the gaps

Spot contradictions between documents, track requirements across files, and surface inconsistencies that would take hours to find manually.

Ready in seconds

Point Locus at any folder. Re-opens are instant — only new or changed files get re-processed.

Works like any app

A lightweight app that feels part of your OS. No browser tabs, no cloud accounts, no friction.

How your data flows

Your data, step by step

PDFs, Word docs, Excel, PowerPoint, CSVs — all read directly from your machine.

Stays local

Locus builds a search index right inside your folder. Visible, deletable, yours.

Stays local

When you ask a question, only small text snippets are sent securely to get your answer. Never your original files.

Encrypted transit

Every response cites the exact file, page, and section. Nothing stored, nothing logged.

Zero retention

Your documents never leave your machine. The AI only sees small text fragments needed to answer your question.

The rules

What Locus does.
What it doesn't.

What it does
Reads every file in your folder. PDFs, Word docs, Excel spreadsheets, PowerPoint decks, CSVs, plain text.
Answers from the documents only. Every factual claim cites the exact file, page, and section it came from.
Compares across files. Spots contradictions, tracks requirements, surfaces inconsistencies between documents that different people wrote at different times.
Says "That's not in these documents" when it can't find the answer. Then stops. No guessing, no padding, no filler.
Your files stay on your computer. Documents are read and indexed locally. Only small text snippets leave for processing. Nothing is stored.
Builds its brain inside your folder. The index lives as a folder right next to your files. You can see it, move it, delete it. No hidden databases, no cloud storage.
What it doesn't
Does not use outside knowledge. No internet, no training data, no general knowledge. If it's not written in your documents, Locus doesn't know it.
Does not make things up. No "based on my knowledge" or "generally speaking." Every answer is grounded or it's not given.
Does not add opinions or advice. No "you should consider" or "best practice suggests." Locus reports what your documents say. That's it.
Does not chat. It's not a conversational AI. It's not your assistant. It reads folders and answers questions about them.
Does not send your files anywhere. No cloud upload. No sync. No migration. Your folder stays where it is.
