DocsGPT gives legal teams and legal-tech products retrieval with page-level citations across millions of pages and multiple languages, with guardrails and lawyer review as the final step. It powers LexEU's EU-law research over 2.5M+ pages in 6 languages and, at Balt Alnoor, IP drafting that went from 6+ hours to under 5 minutes. Legal-tech companies use DocsGPT as the retrieval and agent layer behind their own product.

Five stages: a client submission or the corpus comes in as filings, PDFs or images; the document parser produces text, with OCR or a vision model where a scan needs it; the model researches across the corpus or drafts against a template; the output is a cited answer or a near-final draft; a lawyer reviews and approves before anything leaves the system.
Citations
The central risk in legal AI is a hallucinated citation, so generation must be grounded in retrieved passages and every citation must link to a real page.
Languages
Multilingual legal terminology defeats general-purpose embeddings; retrieval has to be tuned to the domain and to each language the practice works in.
Review
AI output in legal work is a near-final draft, not a decision: a lawyer's review is the final stage of the pipeline, by design.
Workflow 01
Hybrid retrieval (BM25 + vector) finds the passage; GraphRAG follows multi-hop questions across regulations and case law; every answer cites title, source and page. The Research agent handles multi-step questions with budget controls.
Hybrid retrieval (BM25 + vector) · GraphRAG · citations (title, source, page) · Research agent
Workflow 02
Any Sentence Transformers or remote embedding model can be used; retrieval is language-aware; chunking and query rephrasing are set per source, so a German statute and an Italian judgment do not share one setting.
Sentence Transformers / remote embeddings · language-aware retrieval · per-source chunking and rephrasing
Built for the client · fine-tuned legal embeddings and a domain fine-tuned LLM, as in LexEU.
Workflow 03
A Workflow takes the intake (images, PDFs, filings), extracts text with OCR or a vision model, has an AI Agent node draft a structured description, renders the template as a versioned DOCX or PDF artifact, and stops at a human-approval step before release. This is the IP drafting pattern.

Workflow 04
Anti-hallucination prompts constrain generation to retrieved passages; guardrails run on retrieved sources and on the final answer (banned terms, link policy, LLM-judge policies); human-in-the-loop gates responses and tool calls; per-domain benchmarks assert that answers cite the expected sources before a change ships.

Five controls, in the order they act on a question. None is absolute on its own; together they make a wrong citation detectable and reviewable.
Grounding
Answers are generated only from retrieved passages; anti-hallucination prompts refuse when the corpus does not contain the answer.
Page-linked citations
Every citation carries title, source and page number and opens the source panel on that page.
Source guardrails
Guardrails check retrieved sources and the final answer: banned terms, link policy, LLM-judge policies.

Human-in-the-loop
Responses and tool calls can require approval; drafting ends at a lawyer's approval step.
Benchmark assertions on sources
A per-domain suite asserts that answers cite the expected sources before any change ships.

Managed is the usual posture here: a private instance without operating it.
Law firms typically take a dedicated managed instance or the Cloud plan — the IP drafting deployment runs on cloud models. Firms with residency rules run DocsGPT on-premises with a local model. Legal-tech companies run it in their own cloud as the backend of their product.
Scope, measure, then decide.
Select one corpus and one drafting type
One jurisdiction or practice area for research; one document type for drafting.
Lawyers write 30–50 benchmark questions
Each with the expected sources, so citation accuracy is testable from day one.
Ingest, configure retrieval, run the benchmark
Iterate on embeddings, chunking and rephrasing until the source assertions pass.

Build the drafting workflow with a review step
Intake, extraction, draft, versioned artifact, lawyer approval.
Pilot with a small group
Measure citation accuracy and time per draft against the current process.
For legal-tech products the commercial model is a subscription plus an engineering retainer — see For AI product builders. Firms: Cloud at $20/seat/month or a Managed instance from $2,000/month — see pricing.
