Quick Video Export for Claude

Quick Video Export for Claude Design — Browser Extension

A lightweight Manifest V3 browser extension for Claude Design, Anthropic's AI-assisted animation tool. Claude Design already supports video export, but it's buried a few clicks deep in the Share menu — this adds a small button right on the timeline toolbar that jumps straight to the native export dialog in one click.

What I handled end-to-end:

DOM-based UI injection that matches the host app's existing design tokens and toolbar styling, so the button feels native

Resilient element detection with console warnings that flag if the site's markup changes — so regressions after a redesign are easy to catch instead of failing silently

A custom inline SVG icon (no dependency on the host site's own icon font)

Store-ready packaging for both browsers: manifest configuration, privacy/data-collection disclosures, and full submission to Chrome Web Store and Firefox Add-ons (AMO)

Zero data collection, no tracking, no network requests — everything runs locally in the browser. Free and open source.
