Turnpoint

Turnpoint makes a code change easier to understand. Instead of mentally piecing together a long diff, follow an interactive, handwritten map of the functions, classes and data involved. See what changed, switch between before and after, walk through the affected path, and tap any block for its source file and exact lines. Optional plain-language narration explains the observed behavior without hiding the evidence. Supports JavaScript, TypeScript, JSX and TSX. Static analysis follows relationships in the supplied files; it does not run code, prove runtime behavior or invent missing dependencies. The plugin adds a visual explanation inside the conversation and leaves the host’s built-in diff available. No account or API key is needed. The hosted tools process only the selected source or analysis provided to them, in memory, without storing it. The standalone editor analyzes code locally in your browser.
