Persian and Arabic that read the way they should, inside the tools you already use.

The pain

ChatGPT, Claude, Gemini and Copilot were all built left-to-right first. Paste Persian or Arabic in and it lands left-aligned, punctuation jumps to the wrong end, and mixed sentences with English words or links come apart. The usual browser hacks force the whole page right-to-left and break everything else.

How it works

Detects right-to-left text in the chat and corrects its direction in place.
Leaves code blocks, links and Latin words alone, so mixed sentences stay readable.
Stays out of the way on content that is already correct.
