Private AI for work that matters.

A private operating system for the documents your work depends on. Put them in, ask in plain words, and see exactly where every answer came from before you rely on it.

No card required. Start with one real question.

One workspace: your files, the question, the answer, and the evidence behind it.
Why Zylox is different

Most AI hands you a confident paragraph and asks you to trust it. Zylox shows its working. Every answer points to supporting source material in your own documents, so anyone can review it before relying on it. Private by default, and never used to train a model.

01 / When it counts

Built for work you have to be right about.

What you are working from

An agreement, a lease, a supplier's terms, a quote. Anything that binds you once you put your name to it.

The question

"What am I actually committing to here, and how do I get out of it?"

What comes back

The commitments listed plainly, each one sitting next to the exact clause it came from.

One file, or everything you have ever signed.

The same standard of proof at either end. Start on your own with a single document, and grow into a library you, and anyone you choose to bring in, can answer from.

Renewal is automatic unless notice is given 30 days before the term ends.

One document, one hard question

Drag in the thing on your desk right now. No setup, no configuration, no call. You get a cited answer with sources attached and decide for yourself whether it holds.

Free to try. Bring one real file rather than a sample.

Answered from the shared library
Checked across 214 documents in your library. Four say the same thing.

As it grows · you and anyone you add

Everything you have collected

Years of agreements, packs and case files in one place, so the answer does not depend on what you can remember. Work alone with all of it, or bring in a colleague, a client or your whole firm.

Yours by default. Sharing, permissions and an audit trail when you want them.

And it only reads what the question actually needs.

Zylox finds the relevant passages first and answers from those, rather than pushing everything through the model every time. Efficient by design, less repetition, and a bill that doesn't scale with the size of your folder.

02 / The proof

See the source behind the answer.

Answers keep the supporting source context close to the claim, so the evidence can be checked before a decision is made.

That is the difference between a summary and something you can sign off.

ANSWER
Two accounts make up 41% of Q3 ARR, and the model treats both as fully retained.
Financial_Model_v4.xlsx · Rev tabQ3_Board_Deck.pdf · p.6
SOURCE

“Customer A and Customer B account for 41% of total recurring revenue in Q3. Both are modelled at 100% renewal for Q4, with no risk adjustment currently applied in the forecast.”

Under the answer

How a question gets answered.

Four stages, in order. Each one visible, so the answer is explainable from first upload to final line.

Zylox works from the material you provide and shows what it used.

01
You add material to a workspace
Documents, notes or a folder, into the workspace you choose.
02
Zylox indexes that material
The text is prepared so passages can be found by meaning, not just keyword.
03
A question retrieves passages
Your question pulls the specific passages that bear on it, rather than whole files.
04
The answer cites what it used
The response is composed from those passages, with the page and line range attached.

Zylox reuses document context across tasks.

Most document work is repeated work. Zylox keeps context attached to your workspace so follow-up questions build on what has already been read.

Where it fits

The loops you will run every week.

Turn a folder into a briefing

Drop in a new batch of documents and get back a cited summary you can hand off, refreshed every time the folder changes.

04 / Control

Private by default, controlled by you.

Zylox is built for material you would not paste anywhere else. Access is explicit, sharing is deliberate, and data handling is stated clearly.

Draft ready to review
Step 03
Turn it into work

Write the note, mark up the clause, compare versions, then bring in whoever signs it off.

Two ways to use Zylox

Start on your own with one real file. Bring people in when the work needs them. And when your organisation has requirements the standard route cannot answer, start with those instead.

07 / Questions

Before you start.

What do I need to get started?
A workspace and one file. Create the workspace, drag the document in, and ask your first question. No card and no configuration.
How do I know an answer is right?
+
You check it. Every answer shows the page and line range behind it, and the passage opens beside the answer so you can read the original wording in place.
Is my material used to train Zylox?
+
No. Customer data is not used to train Zylox. Your workspace is private, and access is controlled through roles and authenticated invites.
Can I use it with other people?
+
Yes. Work on your own for as long as you like, then invite the people who need to review or contribute and set what each of them can do.
My organisation has its own requirements.
+
Start with the requirements themselves: access, deployment, onboarding, operational and contractual. We will review the fit and propose an approach rather than putting you through a demo cycle.

Turn the work you already have into answers you can use.

Start with a source document, check the evidence behind the answer, then move the work forward in the same place.
