RTL Extension ავტორი Ali Bahadori

Rastnevis is a lightweight Firefox extension that improves the experience of reading and writing Persian in AI chatbots.
When you open Claude.ai, ChatGPT, or Gemini, the extension automatically:
Renders Persian and Arabic text using the Vazirmatn font with right-to-left (RTL) direction, significantly improving readability for Persian content.
Leaves English text within the same message untouched, preserving the site's original font for Latin characters, so you don't need to manually switch between languages.
Keeps code blocks and monospace content always left-to-right (LTR), since code should always be read LTR even in the middle of a Persian response.
Lets you toggle the extension on or off at any time from the toolbar icon, with the state persisted across browser restarts.
This extension does not collect, store, or transmit any user data or browsing activity; all changes are applied locally to the page's display only.
