VersionStory: Comparison and Redlining for AI native legal teams
Version Story is a web-based software application designed to provide precise document comparison and redlining services for legal teams using AI. The platform utilizes a deterministic Rust-based engine to process Word and PDF files, ensuring that no language model reads the sensitive document content. It supports integration with major AI assistants like Claude and ChatGPT via an MCP server and offers a REST API for broader application development.
- ▪The software uses a deterministic engine to generate redlines, ensuring that no language model accesses the document data.
- ▪Version Story accepts various input formats including DOCX, legacy DOC, native PDF, and scanned PDFs with OCR capabilities.
- ▪The tool outputs redlines in multiple formats such as Word tracked changes, PDF, changed-pages PDF, Markdown, and JSON.
- ▪Internal testing indicated that Markdown redlines are significantly faster and more token-efficient for AI agents to process compared to Word or PDF formats.
- ▪The service is available as a web application, an MCP server for AI assistants, and a REST API for programmatic access.
