Building legal technology the right way
Legal Sensus is a Canadian legal-tech company building AI tools for legal professionals and law students. LEO for practitioners, RAD for students. Document-grounded, Canadian-hosted, and designed to integrate with the tools people already use.
What we do
We build and deploy AI applications for legal practice and education — LEO for lawyers and notaries, RAD for law students. Our focus is responsible engineering: AI that cites its sources, Canadian data sovereignty, integration with existing legal systems, and features designed for how law is actually read, taught, and practised. We're not a single app; we're the team building tools that fit into real legal work.
Our approach
Document-grounded intelligence
Every answer is traceable to a source. Retrieval-augmented generation isn't a feature — it's our foundation.
Built into your stack
Our products integrate with the tools legal professionals already use — Outlook, Drive, case management, document tools. Connective tissue, not walled gardens.
Designed for legal workflows
We study how law is read, taught, argued, and administered. The interfaces and features reflect real legal work, not generic productivity software.
Transparent and auditable
Clear about capabilities and limitations. Every action LEO takes has an audit trail.
Canadian data sovereignty
All data processed and hosted in Canadian cloud regions only. Compliant with Canadian privacy laws and the obligations of professional secrecy.
Responsible deployment
We partner with firms and institutions to introduce AI ethically. Training, change management, and ongoing support — not just software licenses.
The team
A Canadian R&D team combining legal domain expertise with production-grade engineering. We don't just consult — we build, deploy, integrate, and support our products inside real practices.
