Matter-scoped workspaces enable users to upload various legal documents, such as credit agreements and leases, into projects where the assistant maintains full context across conversations and documents. The tabular review feature allows for spreadsheet-style extraction across hundreds of documents, with every cell verifiably cited back to a page and a quote, ensuring accuracy without hallucinated answers.
Mike OS supports reusable workflows, enabling firms to save proven prompts as templates for tasks like CP checklists and credit agreement summaries. The platform is designed to be extended, allowing firms to add practice-specific workflows, integrate their document management systems, and wire in their own citation engines.
Security and compliance are prioritized, with documents never leaving the firm's perimeter, ensuring control over residency and privilege. The platform also offers model choice, supporting Anthropic, Gemini, and OpenRouter-backed models, and includes a full Next.js application, Express API, and object-storage integration for deployment.
Mike OS has been independently tested by legal professionals, demonstrating its practical value in NDA and contract review, multi-document analysis, and project management. While the platform offers significant advantages, it also requires consideration of setup and model costs, and its capabilities in litigation and IP use cases may have limitations.
