RTLY — RTL & Font Tool for AI Chats

Right-to-left text and a clean Persian font for AI chat websites. Free, private and open source.

RTLY makes right-to-left text easy to read on AI chat websites. Most chat sites are designed for left-to-right text. In a Persian or Arabic answer, the lines can sit on the wrong side, punctuation can land in the wrong place, and sentences that mix English and Persian can look scrambled. RTLY fixes this directly on the page, and it does not change the layout of the site. What it does - Checks each message. If it is mostly right-to-left, RTLY sets the text direction to right-to-left. English messages stay left-to-right. - Uses a bundled Persian font for text written in Arabic script. - Keeps the box where you type in automatic direction, so each line follows the language you write in. - Leaves code, icons, menus and sidebars untouched. Controls - Turn RTLY on or off for each site from the toolbar popup, the settings page, the right-click menu, or the keyboard shortcut Alt+Shift+R. - Choose a mode for each site: full, font only, or direction only. - Change the font size from 85% to 120%. - See a live before and after preview on the settings page. - Pick a light or dark theme and an accent color. Works with popular AI chat websites such as ChatGPT, Claude and Gemini. The full list of supported sites is in the user guide. Privacy RTLY has no account, no server, no analytics and no ads, and it makes no network requests. It reads the text on a supported page only to choose the direction, and it never stores or sends that text. Your settings stay in your browser. Good to know Websites change their pages without notice, so RTLY may stop working on a site until it is updated. If a site looks wrong, please report it on GitHub. RTLY is free and open source (MIT license).
