OpusChange por Opus

OpusChange turns visual feedback into instructions an AI coding assistant (Claude Code, ChatGPT, Copilot…) can execute precisely. Click any element, describe the change, and export selectors, DOM paths, styles and JS errors — 100% locally.

How it works
1. Click the OpusChange icon (or Alt+Shift+M)
2. Hover the page — elements highlight like the DevTools inspector
3. Click an element, pick a type (Edit · Add · Remove · Bug · Question) and write your comment
4. Copy the export and paste it into your AI assistant

What each annotation captures
- Unique CSS selector + full DOM path
- Section context, computed styles, attributes, HTML snippet

Built for iteration
- 3 export modes: Fix (strict repairs), Improve (the AI also suggests better), Audit (report only)
- JavaScript errors on the page are captured and included
- Mark annotations as resolved and re-export only what remains
- Annotations persist per URL; PNG capture with badges

Privacy: no account, no server, no network requests. Nothing leaves your browser unless you copy or download the export yourself. Interface in English and French.
