In simple English
This tool runs a team of specialist computer programs that read legal documents and debate their findings. It splits complex review tasks across sixty-seven different expert prompts to check for hidden risks and traps. It asks human users to approve important decisions before any final report is ready. You can run it on your own computer using a local model or connect it to major cloud providers. The software is free to download and use under an open-source licence.
What it is
A multi-agent legal review system built with TypeScript that coordinates sixty-seven specialist AI agents through a debate protocol and verification pipeline. It includes a React dashboard, a background daemon called Clawern, and twenty-one Model Context Protocol tools.
What it is good for
Solo builders and legal professionals who want to experiment with automated document review pipelines and multi-agent debate structures.
- Runs locally with Ollama or connects to cloud providers like Anthropic and Mistral.
- Includes a complete React dashboard with an editorial design language and live activity feeds.
- Provides a large automated test suite with over one thousand tests passing cleanly.
- Requires an external API key and paid account balance to use cloud-based models.
- Running sixty-7 agents through deep debate loops takes several minutes per engagement.
- Uses simple keyword search instead of semantic vector retrieval for its knowledge base.
