The Isaacus API, the world’s first legal AI API, can be used to automate a range of legal information extraction, retrieval and classification tasks, including:
  • Universal classification: classifying and extracting clauses from legal documents based on your own criteria, with no prior examples necessary.
  • Reranking: scoring and sorting legal documents based on their relevance to search queries.
  • Extractive question answering: extracting answers to questions from legal documents with high precision and throughput.
We are currently working on introducing the following new capabilities by October 2025:
  • Embedding: transform legal documents into highly compressed numerical representations that can be used for things like semantic search, clustering and classification.
The best way to get notified is to sign up for an Isaacus account and follow us on LinkedIn. If there’s something else you’d like to see added to the Isaacus API, please let us know and we’ll do our best to prioritize it.
