A git diff is a textual comparison that shows the exact changes between two states of a codebase — lines added, lines removed, and lines modified across every affected file. Developers use git diffs daily during code review and version control, but VidNo repurposes this familiar concept as a content input. When you provide a git diff alongside your screen recording, VidNo gains a precise, structured understanding of what you actually built during the session. Instead of relying solely on visual frame analysis, the diff tells the AI exactly which files changed, how many lines were added or removed, and what the functional impact of each change was. This structured data dramatically improves script quality. The AI can reference specific files, explain architectural decisions in order, and highlight the most significant changes rather than narrating every keystroke. The result is a video script that reads like a thoughtful code review rather than a monotone play-by-play of your screen.
