DocDiffPro

DocDiffPro is a web app (with optional GitHub/GitLab integration) that detects and prevents “documentation drift” across technical artifacts: PRDs, API references, SDK READMEs, release notes, and support articles. It continuously compares related documents, flags contradictions (e.g., parameter names, limits, default values), and generates a short, actionable change list for writers and engineers. Instead of rewriting docs, it focuses on high-signal diffs: what changed, where it’s inconsistent, and who should approve. Teams can define “source of truth” hierarchies (e.g., OpenAPI > README > Help Center) and enforce them via CI checks. This is an AI-assisted app combined with deterministic parsing: it uses structured extraction for specs and lightweight LLM checks for natural-language inconsistencies. The goal is fewer broken integrations, fewer support tickets, and less embarrassing mismatch between product behavior and published docs.
