BIDI - Forge 作者： amirmkazemi

BIDI - Forge fixes the reading order of mixed right-to-left (Persian, Arabic, Hebrew) and left-to-right text in AI chat interfaces, where a single English word, a number, a bullet or an inline code span is enough to flip a whole sentence the wrong way.

It resolves a base direction for each block of a reply — ignoring runs that are technical rather than linguistic, such as inline code, code blocks, URLs, digits and emoji — so a Persian line that opens with useState or 1. stays right-to-left instead of anchoring on its first character.

What it fixes

• Sentences that start with code, a number, a bullet or an English term
• Bullets and list numbers landing on the wrong side, with the wrong indentation
• Items in the same list disagreeing with each other
• Punctuation, quotes and brackets jumping to the wrong end of a sentence
• Persian comments inside code blocks, while the code itself stays left-to-right
• The message box, where each line you type follows its own language

How it works

Rendered replies are never rewritten. The add-on only sets direction attributes and applies a stylesheet, so inline code and links stay intact, copying an answer gives you clean text with no invisible characters, and switching the add-on off restores the page exactly.
