vaulytica

A contract reviewer that gives the same answer every time.

AI contract tools are fluent and fast, and useful for summaries and first drafts. But run the same contract twice and you can get two different answers, neither of which cites where it came from. Vaulytica is the opposite: 1,946 fixed, cited checks that produce the same report on any machine, for free, without your contract leaving your browser.

How the two approaches differ

Same input, same output

Vaulytica is a rule engine, not a model. The same file, engine version and knowledge base always produce the same report, with a hash you can use to prove it.

Every finding is cited

Each finding quotes the clause, gives its position in the document, and names the rule and the statute, regulation or drafting standard behind it.

Nothing leaves your device

Most AI tools send your document to a hosted model. Vaulytica has no server to send it to.

Every check, listed

Every applicable rule runs on every document, and the audit trail lists the rules that found nothing as well as the ones that fired.

Free, with no usage limits

No per-document pricing, no seats, no trial. MIT-licensed and open source.

Where AI is better

Explaining a clause in plain English, summarizing a long agreement, or drafting new language. Vaulytica does none of those, and says so.

Use both

The two approaches answer different questions. An AI assistant helps you understand a document; a deterministic checker runs the whole checklist the same way every time and gives you a record you can show someone else. Many reviewers run Vaulytica first, then spend their judgment — or an AI tool — on the findings it surfaces.

What you get

A page that says what to raise and why

Each item opens to the clause it is about, the reason, the rule's suggested change and its source.

Your draft back with comments

Drop a .docx and get it back with each item as a Word comment on its clause.

Everything else, if you want it

A Word report, dates for your calendar, and spreadsheets of obligations and fixes.

How it works

  1. Open vaulytica.com — no account, nothing to install.
  2. Drop your PDF or DOCX, or paste the text. It is read inside your browser tab; nothing is uploaded.
  3. Get your report in seconds. The document type is detected and only the checks that belong to it run.

Questions

Does Vaulytica use AI at all?

No generative AI, no language model and no probabilistic component. The checks are deterministic rules.

Is deterministic review less capable than AI review?

It is narrower. It cannot interpret or draft, but it runs the same checks on every document, quotes only text that is in the document, and each result can be traced to its source.

Why would a lawyer prefer a deterministic tool?

Because the output can be cited, reproduced and audited. Many courts now require disclosure or certification of generative-AI use in filings, and a deterministic tool can document that none was used.
