What it does

When the AI proposes a refactor, the only safe way to trust it is to see exactly what changed. A side-by-side diff lays the before and after next to each other, with the changed lines highlighted.

VibeGear ships Monaco (the VS Code editor) under the hood — so syntax highlighting, indentation, brackets, and folding all work the way you expect. Both panes are editable, so you can experiment in place.

✓20+ languages with proper syntax highlighting
✓Both panes editable — tweak the AI’s suggestion in-place
