## Description

<a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/cf6f55cbba6731f7030d49478c86cb1b6c503e9ea8cb3f1a019bd0e646726ebe/http%3A//Claude.ai" rel="nofollow">Claude.ai</a> does not set the correct text direction on message content, so Hebrew, Arabic, Farsi, and other right-to-left scripts render with broken alignment, misplaced punctuation, and reversed parentheticals. This extension fixes that.

[Need a desktop-app solution for Windows or macOS? checkout the repo: <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/21b872a71fa452b7d3ef5a817b68be17468ac45008b740790f4808661c617ad7/https%3A//github.com/BloodyDeathRoll/RTL-Claude-App/releases" rel="nofollow">https://github.com/BloodyDeathRoll/RTL-Claude-App/releases</a>]

How it works:
<ul><li>Each block of text in a Claude message (paragraphs, list items, headings, blockquotes, table cells) is given the standard HTML attribute dir="auto", which lets the browser's built-in Unicode bidi algorithm pick the correct direction based on the first strong-directional character in the block.</li><li>This handles mixed-language messages correctly. An English paragraph followed by a Hebrew paragraph followed by code will each render with the right direction, automatically.</li><li>Code blocks (pre, code, kbd, samp, var) are explicitly forced to dir="ltr", so file paths, shell commands, and source code stay correctly oriented even inside an otherwise right-to-left message.</li><li>A MutationObserver re-applies the fix as Claude streams new tokens in, so it works during live response generation, not just on already-rendered content.</li></ul>
Click the toolbar icon to toggle the extension on or off. The setting persists across page loads. When toggled off, all changes are reverted immediately without needing a reload.
