AI search for law firm matter files, cited to the page
Corpus is AI search over your own firm’s files. You ask a question in plain words, and it answers from your matter files with a citation to the document and page. If nothing on file supports an answer, it is designed to say “Nothing on file.” It is not legal advice and not e-discovery software. A lawyer reviews every answer.
The answer is on file. Finding it is the work.
The answer is in a closed matter somewhere. Finding it means asking around the office, then opening old folders and scanned exhibits one by one.
- “We negotiated a cap like this for another client. Which matter was it?”
- “Find the brief where we made this argument, and the exhibit we relied on.”
- “What did the second amendment change in the assignment clause?”
- The answers sit in matter folders, scanned exhibits and old drafts that one partner remembers.
Answers from your own files, cited to the page.
- We load a copy of your matter files saved as PDF: pleadings, briefs, contracts and amendments, correspondence and scanned exhibits. Corpus is retrieval-augmented generation (RAG): it answers from those files.
- Current You ask in plain words. Corpus searches by exact words and by meaning, then writes a short answer with citations to the document and page. Open a citation and the page opens with the passage highlighted, so you can check it.
- Current If nothing on file supports an answer, it is designed to say “Nothing on file” instead of guessing. An empty result does not prove that no such record exists.
- Current Access by role: files a role cannot open are removed before search runs, so answers never draw on them. In the demo, roles are illustrative and anyone can switch them. Set up for you Tying roles to your named people is part of full-deployment setup.
- Current Version history for drafts: each saved version shows who saved it, Compare shows what changed, and you can restore an earlier one. In the demo this covers fee, SOQ and contract drafts.
- Corpus reads PDF files, including scanned pages read by OCR. Set up for you OCR of your own scans is planned on the call and done during setup.
- Set up for you Corpus is cloud-agnostic: it runs on AWS, Azure, Google Cloud, or your own servers. It uses an open-weight model and no public AI API.
Example questions, not results
These questions are examples written for this page. They are not results: Corpus has no customers in this industry yet, and the live demo is built on engineering documents.
- Which past matters involved a liability cap tied to the fees paid?
- In this client’s master services agreement, what notice period applies to termination for convenience?
- Which of our briefs argued that the arbitration clause did not survive termination?
- Where in the deposition transcript does the witness discuss the delivery date?
Corpus finds and cites. People decide.
- A lawyer reads the cited page before relying on it.
- Whether the cited document is the final, signed version.
- Whether the law has changed since the document was written. Corpus answers from your files, not from current law.
- Who may see a matter. Corpus removes files a role cannot open, and your people decide who gets which role.
Corpus is not legal advice and does not replace a lawyer’s judgment. It finds and cites; your lawyers decide.
Start with a free call. Then one real project.
- A free 30-minute call first. We talk about your files and the questions you need answered.
- Then a $5,000 pilot on one real project or pursuit, at a fixed price.
- We work from a copy of that project’s PDFs. Your originals are not touched.
- You ask your own questions, open the citations and judge the answers yourself.
- The $5,000 is credited toward setup if you sign a deployment within 60 days of the pilot's end.
- Our commitment In the pilot, your files are never used to train or fine-tune a model. In full deployment, fine-tuning on your files happens only if you agree in writing.
- Our commitment When the pilot ends, we delete the copy within 7 days and confirm it in writing.

The live demo is built for engineering firms: public engineering documents filed under fictional sample firms. Its search also reaches a public-domain collection of U.S. court opinions. There is no demo built on another industry’s files. It shows what works the same in any industry: page citations, “Nothing on file” and roles.
Our earlier page, AI Automation for Legal Teams, describes a separate 2025 service that we are not taking new clients for.
→ Corpus by industryFrequently asked questions
Is Corpus e-discovery software?
No. Corpus answers questions from your own firm’s files, with page citations. It does not do collection, review coding or productions. Use it to find what your firm already wrote.
Does Corpus give legal advice?
No. It finds passages in your files and cites the page. A lawyer reads the cited pages and decides what they mean.
Can we keep a matter away from some people?
Yes, by role. Files a role cannot open are removed before search runs, so answers never draw on them. In the demo, roles are illustrative and anyone can switch them. Set up for you Tying roles to your named people is part of full-deployment setup.
Do you have customers in this industry?
Not yet. Corpus has no customers in this industry. Engineering firms are our first, worked-out example, and the live demo uses fictional engineering firms.
Where do our files go?
Set up for you Corpus is cloud-agnostic. It runs on AWS, Azure, Google Cloud, or your own servers. It uses an open-weight model, and nothing goes to a public AI API. In the pilot, your files are never used to train or fine-tune a model. In full deployment, fine-tuning on your files happens only if you agree in writing. We don't have a SOC 2 report, which is one reason you can choose your own servers.
