sem is a semantic version control CLI built on top of Git that parses code with tree-sitter and diffs, blames, and analyzes impact at the entity level (functions, classes, methods) instead of lines. It supports ~30 languages, works in any Git repo with no setup, and exposes an MCP interface designed for coding agents.

Use cases

• show which functions changed in a commit instead of line diffs
• find who last changed a specific function with semantic blame
• analyze what code depends on a function before refactoring
• give coding agents more accurate diff context via MCP
• review pull requests at the entity level across many languages

When to choose

• you want entity-level diffs, blame, or impact analysis on top of an existing Git repo
• you are building or using AI coding agents that need structured change summaries
• you work across many languages and want one zero-config tool

When to avoid

• you need a full replacement for Git rather than a lens on top of it
• your code is in a language tree-sitter does not cover
• you only need plain line diffs and standard git tooling suffices
