AI Legal Research Across Your Own Documents
Keyword search finds the words you thought of. Concept search finds the passage that says the same thing differently — which is usually the one you needed.
Search by concept, not by exact phrase
Legal writing says the same thing many ways. Ask about a standard, a doctrine or an argument and the retrieval layer surfaces passages that match in meaning, including those that never use your search terms. Keyword search remains available and instant when you know the exact language you are after.
Grounded in your own library
PDF.LEGAL searches the documents you have indexed — your briefs, opinions, filings and reference material. That is a deliberate constraint: answers come from a corpus you control and can verify, rather than from a model's recollection of the law.
Findings you can carry into a memo
Results arrive with page and line references, so a research memo assembled from them is citable as written. The verification step is reading the cited passage, which is where it belongs.
Why AI legal research needs verifiable citations
Courts have sanctioned filings built on AI-invented authority. A retrieval-grounded system answers this structurally: it can only cite documents that exist in your index, and it tells you where in them the support sits. Verification is still required — but it is now possible in seconds.
What you get
- Semantic retrieval that matches meaning, not just strings
- Instant keyword search when you know the exact phrase
- Every finding tied to a document, page and line
- Answers restricted to your own indexed corpus
- Local model option so research stays confidential
Frequently asked questions
Does PDF.LEGAL search public case law databases?
No. It searches the documents you upload and index. That is what makes every citation traceable to a source you hold — it is a research tool for your own corpus, not a substitute for Westlaw or Lexis.
How does it avoid hallucinated citations?
Answers are generated from passages retrieved out of your indexed documents, and each carries its page and line. A citation that is not in your corpus cannot be produced, and every one that is can be checked against the text.
Can research run without any cloud AI provider?
Yes. With the local Ollama provider the retrieval and generation both run on your own hardware, with no outbound requests.
