The business

Canadian legal professionals who research case law and statutes every day, from solo practitioners to firm research teams.

The problem

  • Relevant authorities are hard to find across a very large collection, and decisions are long to read.
  • AI summaries are useless to a lawyer unless every answer stays connected to the source.

How we solved it

  1. 01

    Retrieval-augmented search and chat over more than 1.5 million legal documents, combining keyword search, vector retrieval and structured filters for judge, jurisdiction, court level and counsel.

  2. 02

    Case summarization, document upload and analysis, follow-up questions and source-linked results.

  3. 03

    Subscription billing through Stripe and background processing with RabbitMQ workers.
