Horizon
A private AI legal associate for solo lawyers and small firms.
Horizon helps lawyers get through case files faster. Upload the documents for a matter, ask questions in plain language and get answers drawn from those documents, with key facts pulled out and long files summarised.

01 · The problem
A single case can run to hundreds of pages of pleadings, contracts, evidence and judgments. Solo practitioners and small firms rarely have juniors to read them, so hours go into finding facts buried somewhere in the file.
Facts scattered across many long documents
Hours of manual review before strategy work can start
General chatbots not designed for confidential case material
02 · What Horizon does
Horizon indexes the documents in a case and uses retrieval-augmented generation to answer questions from them. Instead of reading every page to find a date, a party or a clause, the lawyer asks, then verifies what matters before relying on it.
Questions answered from the case's own documents
Fact extraction and summaries of long files
Reasoning across several documents in the same matter

04Questions
Does Horizon replace a lawyer?
No. It speeds up document review and fact-finding. Judgment, strategy and advice stay with the lawyer, and anything Horizon produces should be checked before it is relied on.
What can I upload?
Case files, contracts, evidence, judgments and other documents that belong to a matter.
Who is Horizon for?
Solo lawyers and small law firms that need to review large case files without a large team.
