AI Analysis

●MidShip It

Tree-sitter AST parsing is smarter than diffs, but docs-sync tools already exist.

Strengths

•Tree-sitter AST parsing understands actual symbol changes, not just text diffs.
•Local LLMs mean no code leaves your machine—privacy-conscious by default.

Weaknesses

•No repo link or demo provided—can't verify implementation quality or actual output.
•Mintlify, Swimm, and ReadMe already tackle documentation drift with established solutions.

Post Description

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.
