The decision inside it

A change is a whole phrase, and your edits are safe

A word-level diff of a rewritten sentence turns into confetti. Neighbouring edits are merged into one phrase you decide once. If you typed over a phrase since the suggestion was made, Accept asks "Replace your edit?" instead of throwing your words away.

When to use it

Use Inline Diff to review an AI rewrite of prose: changes are whole phrases you accept or reject in the text, by click or by key, with undo. Pass the original and the suggestion, or changes you worked out yourself. For structured record changes use Dry-Run Preview.

Installation

How you get it

Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.

Use Liro's Inline Diff for this.
Install it: npx shadcn@latest add @liro/inline-diff
(the @liro registry is set up in components.json, with LIRO_KEY in .env.local)
Import it from @/components/ui/inline-diff.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.

For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Pro components install through the @liro registry with your CLI token: see the Namespaced tab.

Usage

components/review-rewrite.tsx
import { InlineDiff } from "@/components/ui/inline-diff";

export function ReviewRewrite({ draft, rewrite, save }: { draft: string; rewrite: string; save: (text: string) => void }) {
  return (
    <InlineDiff
      original={draft}
      suggested={rewrite}
      onDone={(result) => save(result.text)}
    />
  );
}

Props

States

All of them are drawn by the component. None is left for you to design.

  • Suggestions
  • Change open
  • Accepted
  • Rejected
  • Overlaps your edit
  • All decided
  • Read only

Accessibility

  • Keyboard reachable throughout, in visual order
  • Focus trapped in overlays, Escape closes them
  • Focus returns to whatever opened it
  • Live regions announce what changed, not that something did
  • Honours prefers-reduced-motion

Responsive behavior

  • Sizes to its container, not the viewport
  • Usable from 320px up
  • Pointer-based interaction, so trackpad and touch both work
  • No hover-only affordances
