Ask your documents anything

Ask your documents
anything. Stop overpaying

Your 200-page contract

Sent in full, every single question…

Q: When does the renewal clause trigger?

The problem, in one picture

Ten questions.
One document.
Paid for ten times.

That is how most AI tools charge you today — the whole document goes out with every question. Ligus flips it: the document is read once, on your machine, and each question only needs the small part it is actually about.

up to ~95%

Not a rounding trick. The same answer, from the same document — with the repeated full-document charges cut out.

Read once

Then ask forever. Your files stay on your machine.

Multi-part questions, answered in full

“When was it approved, how many bays were added, and when did the work finish?” — all three parts, not just the first one it noticed.

Two kinds of questions, two clear answers.

If you ask about your document and the answer is not in it, Ligus states that directly — “not stated in the document.” It does not estimate, fill in, or invent a figure.

For example, if you ask for a supplier's tax ID that the contract never lists, a careless tool may invent a number that looks real. Ligus answers: “Not stated in the document.” In a contract, a bill, or a medical record, a wrong number is worse than no number.

If your question is about something outside your document, Ligus answers from the AI service's general knowledge and labels it as such. It is never presented as coming from your document.

Every answer shows its source. Nothing is guessed, and nothing is mislabelled.

How it works

Three steps. No learning curve.

01

Drop in your document

Contracts, reports, manuals, research, code, tables, even scanned pages. It is read on your machine, not uploaded to a server farm.

02

Ask anything

Dates, figures, clauses, summaries, comparisons. One question or twenty — and multi-part questions get every part answered.

03

Get the answer, from the document

With nothing invented. If your document doesn't state it, Ligus says so.

And your key? You bring it, it stays with you.

Ligus has no account and no subscription of its own to learn — you simply paste the key from the AI service you already use, once, in Settings. You choose how long your browser keeps it (an hour, a day, a week, or until you clear it), and it is never stored on our side or in any log. With each question, only two things ever leave your machine: the question itself, and the relevant part of your document that question needs — sent to your AI service, and nowhere else. The rest of your document never leaves. That is the whole learning curve.

Who it's for

Not for everyone. For people who live in documents.
