Domain: Real estate legal due diligence

Orbital needed to help lawyers analyze hundreds of pages across multiple property documents and produce lease-reporting answers with citations.

Architecture

Orbital Copilot is a real-estate legal agent that evolved beyond classical ML and simple RAG. An LLM “brain” is paired with planning, memory, and tool use so it can read hundreds of pages across multiple PDFs, follow trails between leases and deeds, consult specialized tools or legal knowledge such as land-registry data, reason about whether to dig deeper or ask for missing documents, and return lawyer-reviewable answers with source references and transparent reasoning.

Data flow

A lawyer uploads lease and related real-estate documents, then asks a legal question or runs a lease-report template. Orbital Copilot interprets the question, searches and reads relevant sections across documents, follows definitions and document trails, optionally consults legal tools or knowledge sources, reasons about whether the answer is complete or more evidence is needed, then presents a response with references so the lawyer can verify the primary evidence.

“When prompted with the query “What is the rent and how has it been varied?”, Orbital Copilot leaps into action.”article, stated
“It begins by understanding the question’s context and the documents at hand. Then, it meticulously searches and reads the pertinent sections in both documents.”article, stated
“Finally, Orbital Copilot analyses its findings, formulates a response, and presents it for review.”article, stated
“Orbital Copilot indicates the parts of the PDF documents it consulted, facilitating direct navigation to the primary evidence supporting its answers”article, stated

Why this architecture

Orbital argues that real-estate legal due diligence needs an agent, not a wrapper around GPT-4, because lawyers follow document trails, resolve definitions, consult external legal data, and decide whether context is complete. Simple RAG is useful for one-off questions, but agent planning, memory, and tools are needed for lease-report workflows over long multi-document evidence.

“Such a system is good for simplistic tasks but has several limitations when applied to the type of work lawyers typically do when performing due diligence.”article, stated
“The real long-term value is a dynamic AI assistant built on the AI Agent architectural pattern.”article, stated
“This architecture, when expertly constructed, harbours the potential to transform the legal field. It transcends the more simplistic notion of being merely a thin wrapper around GPT-4 or a “ChatGPT for lawyers”.”article, stated

Scale

Alternatives considered (roads not taken)

Classical supervised ML for legal text classification/question answering

Rejected because: It required labeled datasets and did not provide the multi-document reasoning and dynamic workflow Orbital wanted.

“In the early versions of LegalTech, NLP-based solutions primarily relied on classical supervised ML techniques. This involved collecting extensive labelled datasets and training various supervised ML models for text classification and question answering.”article, stated

Simple LLM/RAG app for summaries and one-off questions

Rejected because: Orbital says RAG is common and useful for simple tasks but limited for lawyer due-diligence workflows.

“This is the most common type of system that many companies are currently building. Such a system is good for simplistic tasks but has several limitations when applied to the type of work lawyers typically do when performing due diligence.”article, stated

Opaque generated legal summaries

Rejected because: Lawyers need source navigation and transparent reasoning to verify the answer.

“Like consulting a junior lawyer to ask how they came to their conclusion, it transparently reveals its thought process and how it arrived at specific conclusions”article, stated

Patterns

rag-retrieval (document-intelligence)

The legal agent grounds answers in retrieved real-estate legal text and citations.

“These systems can be advanced further by incorporating techniques such as retrieval-augmented generation (RAG) which enhances their abi”article, implied

tool-use-orchestration (agent-architecture)

Orbital positions the product as a domain-specific AI agent, not a simple chatbot wrapper.

“Orbital Copilot today stands as the first product of its kind in the industry: a real estate, domain-specific AI Agent that offers unparalleled analysis, review, and reporting capabilities across multiple real estate legal documents.”article, stated

Tradeoffs

How to build trust with lawyers.

Chose transparent reasoning with source citations over opaque generated summaries.

Rationale: Legal users need to verify the basis of answers before relying on them.

“uments, answers complex queries by following information trails across documents, and provides transparent reasoning with source citations.”summary, stated

Legal AI architecture.

Chose agent with planning, memory, and tool use over simple RAG or a GPT-4 wrapper.

Rationale: The agent pattern supports multi-document legal reasoning, completeness decisions, and tool-assisted evidence gathering.

“Weng emphasises that the core of an AI Agent is the LLM, functioning as its ‘brain’, complemented by three critical components: Planning, Memory, and Tool Use.”article, stated

LLM quality versus cost and capacity.

Chose advanced LLMs like GPT-4 for high-accuracy legal analysis over cheaper or less capable models for extensive documents.

Rationale: Accuracy for lawyer clients justified higher model cost, token throughput limits, and reliability management work.

“Utilising state-of-the-art LLMs for thorough analysis of extensive legal documents, often running into hundreds of pages, is crucial for achieving the accuracy our lawyer clients depend on.”article, stated

Gotchas (what bit them)

Classical ML and simple LLM apps were not enough for real-estate legal workflows.

Root cause: The work required following information trails across many documents and explaining reasoning.

Resolution: Evolve toward agentic planning, memory, tool use, and transparent citations.

“The system analyzes hundreds of pages across multiple legal documents, answers complex queries by following information trails across documents, and provides transparent reasoning with source citations.”summary, stated
