Show HN: DocDrift – Use Tree-sitter and Local LLMs to fix stale documentation

I tried to submit the link directly, but my account is currently restricted.

I built DocDrift because I got tired of documentation "lying" after a code change. Every time a function signature or logic changes, the README slowly rots until it's useless.

It uses Tree-sitter for AST parsing to actually understand which symbols changed (functions, classes, etc.), then uses semantic search to find the related documentation sections and suggests fixes.
