How AI is used
Lix is an embeddable version control system designed to be imported as a library. It is built for applications and AI agents that need to track changes in structured data and documents using semantic tracking rather than line-based diffs.
The tool is designed for software companies building applications in fields such as health, finance, and design. It allows developers to implement branching, merging, and rollback capabilities within their own software architecture, supporting a workflow where AI agents propose changes in isolated versions for human review.
Lix tracks changes at the entity level, such as a specific cell update in a spreadsheet or a property change in a JSON file. This is achieved through a plugin system and an underlying SQL-backed storage layer, making history and diffs queryable via SQL.
Buyers should note that Lix is currently in alpha and is primarily available as a JavaScript/TypeScript SDK, though other languages are listed in its design proposals.
Key Features
Semantic Entity Tracking
Tracks changes at the object or entity level, such as a specific property in a JSON file or a cell in a spreadsheet.
Branchable Change Control
Supports creating named versions and branches to isolate changes before merging them into the main state.
SQL-Backed Storage
Uses SQL databases as the engine and persistence layer, allowing history, versions, and diffs to be queried using SQL.
Plugin System for File Formats
Supports structured and binary formats including JSON, CSV, Excel, PDF, and Word through plugins.
Change Proposals
Supports a workflow where changes are proposed, reviewed, and then merged.
Attribution and Blame
Allows users to identify which entity was changed and when the change occurred.
Use Cases
AI Agent Sandboxing
Creating an environment where AI agents can modify files with the ability to track and roll back changes.
Human-in-the-Loop Review
Supporting workflows where an AI proposes edits to a document and a human user inspects the semantic diff before approving the merge.
In-App Version Control
Embedding branching, merging, and audit trails directly into a business application for structured data.
Document Audit Trails
Maintaining a queryable history of modifications for applications that update Word or PDF documents.
FAQ
Is Lix a replacement for Git?
- No, Lix is not designed as a Git replacement. It is an embeddable library meant for applications and AI agents to track semantic changes in documents and structured data.
Which file formats does Lix support?
- Lix supports JSON and CSV, and supports Excel, PDF, and Word through its plugin system.
What programming languages are supported?
- Lix is currently available as a JavaScript/TypeScript SDK, with Python, Rust, and Go mentioned in design proposals.
How does Lix handle data storage?
- Lix uses SQL databases (such as SQLite or Postgres) for its query engine and persistence layer, which makes history and diffs queryable via SQL.
