Legal intelligence. Built into the way the world works.
ThemisOS brings legal knowledge, an assistant that understands your matters, and your workflows together in one connected environment.
It helps organisations understand legal information, do legal work with a record of every step, and open that work to their own software.
From a single contract review to a full due diligence, the work stays connected, sourced and under the control of the people responsible for it.
Legal intelligence should not exist in isolation.
Organisations operate across complex legal environments.
Contracts, legislation, regulatory obligations, disputes, corporate records, legal teams and business systems all generate information and work that must be understood and coordinated.
Yet these activities remain fragmented across disconnected software, manual processes and isolated AI tools.
ThemisOS brings them together.
It provides a shared foundation through which legal knowledge, the Agent, workflows, documents and your own software operate as one connected environment.
Not another isolated legal application.
An infrastructure layer for legal intelligence.
One foundation. Every dimension of legal work.
ThemisOS is built around interconnected infrastructure designed to support the entire lifecycle of legal work.
Intelligence Engine
Legal intelligence grounded in knowledge and context.
Research legislation and judgments with cited answers, analyse contracts, review documents, run due diligence and simulate legal scenarios.
The Agent
An assistant that works with the context of your matter.
Ask questions, draft and review with the matter's documents, facts and people in view. The Agent proposes, a professional decides, and every run is recorded.
Context Engine
Intelligence that understands the environment in which work happens.
Bring matters, people, documents, contracts, legal authorities and obligations together so that each piece of work starts with what is already known.
Knowledge Fabric
A connected foundation of legal and institutional knowledge.
Structure legislation, judgments, professional research, precedents, organisational policies and matter records into searchable, traceable knowledge.
Workflow Engine
Turn legal intelligence into operational outcomes.
Coordinate matters, assignments, approvals, compliance checks, document requests and reviews, with a record of who did what.
Connectivity
Make legal intelligence available to your own software.
Connect your applications through a documented API, scoped keys and webhooks.
Trust and Governance
Govern every interaction, operation and decision.
Enforce identity, permissions, confidentiality, ethical walls, human approval and audit trails throughout the platform.
Assistance that proposes. People decide.
The Agent works with the documents, facts and people of a matter in view. It answers from your own legal knowledge with citations, drafts and reviews, and shows what it relied on.
It never acts alone on anything that matters. It proposes, a professional decides, and the run is recorded.
Skills let a practice teach the Agent how it works, and an administrator can pause it at any time.
Sourced. Reviewed. Recorded.
An answer shows the passages it came from. A draft is a proposal until a lawyer accepts it.
Every run is logged, and the practice controls who can use it.
Intelligence is only as useful as the context behind it.
ThemisOS connects information across the legal and organisational environment.
It relates people, contracts, legal authorities, matters and obligations to one another.
This lets the Agent and your own tools work with the relevant context rather than isolated documents or disconnected conversations.
What anyone sees is limited by their permissions and by ethical walls, and the sources behind an answer are shown.
Put legal intelligence inside your applications.
ThemisOS makes its capabilities available to developers through a documented API.
Themis API
Reach legal research, contract intelligence, document analysis and due diligence through structured, versioned endpoints, with scoped keys and usage metering.
Events and webhooks
Receive a signed notification when something changes in your environment, and respond with your own systems.
Sandbox and production
Build against a sandbox environment first, then move to production with separate credentials.
One infrastructure. Every organisation.
ThemisOS is designed to support legal operations across industries and organisational structures.
Legal Services
Research, drafting, matter management, litigation support, client collaboration and legal operations.
Banking and Financial Services
Contractual obligations, compliance workflows, screening, governance and financial services legal operations.
Insurance
Policy intelligence, claims collaboration, coverage analysis, insurance disputes and regulatory operations.
Corporate Organisations
Commercial contracts, corporate governance, legal requests, regulatory obligations and enterprise legal operations.
Government and Public Institutions
Legislative research, institutional workflows and document management.
Investment and Transactions
Due diligence, corporate records, transaction documents, legal risk and closing coordination.
Each environment uses the same underlying infrastructure while adapting capabilities, workflows, permissions and integrations to the organisation.
Built for environments where information matters.
ThemisOS is designed to support sensitive legal and organisational operations.
Its governance includes:
- Organisation-level data isolation.
- Granular user and agent permissions.
- Matter-level confidentiality.
- Ethical walls and restricted access.
- Document and communication controls.
- Human approval policies.
- Execution and activity audit trails.
- Source and context provenance.
- Data retention and legal holds.
- Scoped, revocable API keys.
Consequential legal decisions and actions remain with the people responsible for them.
Use it in Themis, or from your own software.
Organisations can work in Themis directly, or connect their own applications to it through the API and webhooks.
Build on a more intelligent foundation.
Legal work is becoming increasingly connected, complex and data-intensive.
The infrastructure supporting it should evolve accordingly.
ThemisOS gives organisations and developers a foundation for sourced, reviewed and recorded legal work.
One infrastructure. Every organisation. Intelligence that gets work done.
