Claude Design Chat Widener

Widen the cramped Claude.ai/design chat panel. Drag-to-resize or use a slider, with your preferred width saved automatically.

Claude Design Chat Widener fixes the narrow, fixed-width chat sidebar on claude.ai/design — the panel that squeezes every message into a ~301px sliver. WHAT IT DOES • Drag the panel's right edge to resize it live, just like a native split view • Or open the toolbar popup and use the slider / number box / presets (360, 480, 600, 760px) • Your chosen width is saved and restored automatically on every visit WHY YOU NEED IT Claude's design chat panel is too narrow to comfortably read longer messages or code blocks. This extension overrides that fixed width and keeps it applied even as the page re-renders during navigation. PRIVACY 100% local. No data collection, no network requests, no analytics. The only permission requested is "storage," used solely to remember your preferred width in your own Chrome profile. Works on: claude.ai/design
