The agent
Fifteen centuries ago, Emperor Justinian organized Roman law into a single coherent code. Today, Justinian is Vulcan’s smartest AI agent for government and legal work: it builds secure applications, researches across 157 billion legal records, and investigates and audits complex financials, every answer reasoned from primary sources and cited.
Secure app building
Justinian securely builds and deploys applications, dashboards, and internal tools inside the agency boundary. Ask for the tool your team needs, and it ships where your team already works: our platform, email, and Slack.
Legal research
Justinian answers legal, policy, and regulatory questions with citations back to the primary sources it read, and drafts the memos, rules, comment responses, redlines, and reports your team can verify line by line.
Security
Justinian runs entirely in AWS GovCloud (US), architected to the FedRAMP Rev. 5 baseline, so federal and state agencies can adopt it as government AI infrastructure.

Justinian, answered
Justinian is a legal AI agent built by Vulcan Technologies. It plans research, reads primary law, drafts work product, and verifies every claim against source.

Justinian runs on the largest legal and policy database in the world: 157 billion records spanning primary law, court records, every municipal code, public finance, health, environment, energy, labor, education, transportation, agriculture, disclosures, and state operational data. The full catalog is published on the coverage page.
Law firms, in-house legal departments, policy and compliance teams, and government agencies use Justinian for research, drafting, citation checks, and regulatory analysis. Current law students get free access.
Yes. Vulcan is FedRAMP Ready and listed on the FedRAMP Marketplace. Justinian runs entirely in AWS GovCloud (US), architected to the FedRAMP Rev. 5 baseline and independently assessed by a 3PAO, so federal and state agencies can adopt it as government AI infrastructure.
Justinian is a legal AI agent, not a chatbot. It plans the research path before drafting, follows the citation graph across statutes, regulations, and precedent, and attaches the source trail to every claim so reviewers can verify the work instead of trusting a black-box summary.
Justinian is available on the web, as macOS and Windows desktop apps, inside Slack, and by email at justinian@vulcan.app for account holders.
