Open-source legal platform to analyze documents, automate workflows, and draft contracts. Offers full control and private data hosting.
What is MikeOSS?
MikeOSS is an open-source artificial intelligence platform designed specifically for the legal sector. It is a Legal AI solution that legal teams can fully run, inspect, and control within their own environment. Unlike proprietary tools, this application allows law firms and legal departments to maintain total ownership of their technology and processes, eliminating dependency on third-party vendors and per-seat subscription models.
MikeOSS operates through an advanced chat interface capable of processing complex legal documentation, such as credit agreements, stock purchase agreements (SPAs), or commercial leases. It utilizes state-of-the-art language models to provide evidence-based responses with direct citations from uploaded documents, ensuring the traceability and accuracy of information. As a self-hostable tool, it can be deployed on on-premise servers or private clouds, ensuring that regulatory compliance and attorney-client privilege remain under the organization’s strict control.
The tool organizes work through project-based workspaces, allowing the assistant to maintain full context across multiple conversations and files within a single transaction. Key functional capabilities include:
- Automated Workflows: Allows users to save optimized prompts as reusable workflows for recurring tasks, such as generating conditions precedent (CP) checklists, credit agreement summaries, or change-of-control clause reviews.
- Tabular Review: Facilitates data extraction into spreadsheet formats from hundreds of documents simultaneously. Each generated cell includes a verifiable reference to the page and the exact quote from the original document, minimizing the risk of hallucinations.
- Contract Drafting and Editing: The assistant enables the drafting and editing of legal documents from start to finish, integrating case law research and due diligence analysis features.
MikeOSS’s open-source approach offers strategic benefits for the legal industry. Since there are no "black boxes," technical teams can audit how prompts are built and how data flows. Furthermore, the platform is highly extensible, allowing for the integration of proprietary document management systems (DMS) or specific citation engines. This flexibility, combined with the absence of per-user licensing fees, makes MikeOSS an efficient choice for firms seeking legal digitization without compromising information security.
