Semantic version control => entity-level diffs, blame, and impact analysis on top of git. 26
languages via tree-sitter. Built for coding agents.
Instead of lines changed, sem tells you what entities changed: functions, methods, classes.
sem is a semantic version control tool that works on top of Git. It parses your code with
tree-sitter, extracts every function, class, and method as an entity, and diffs at the entity level
instead of lines. This means you see "function blahh was modified" instead of "lines x-y changed."
It works in any Git repo with no setup.
