Bidi

BiDi — Smart RTL Direction for Hebrew, Arabic & Persian

Are you typing in Hebrew, Arabic, or Persian and the text appears misaligned? BiDi fixes that.

The Problem

Many websites default to left-to-right (LTR) text direction. When you type or read Hebrew (עברית), Arabic (العربية), or Persian (فارسی), text often appears out of place — starting from the wrong side, with punctuation misplaced, or entire paragraphs reversed.

The Solution

BiDi adds a small, powerful popup to your browser that lets you fix text direction on any website in one click. Choose from three modes, and BiDi remembers your preference for every future visit.

Three Modes

🔘 None — Standard browser behavior. No changes applied.
🔵 Auto (Smart Detection) — The intelligent default. BiDi scans the page for elements containing RTL characters and applies right-to-left direction only to those elements. Everything else stays LTR. Works beautifully on mixed-language pages.
🔵 Full RTL — Forces the entire page to use right-to-left direction. Ideal for websites that are primarily in Hebrew or Arabic.

Key Features

✅ Per-site memory — Set your preference once per website. BiDi remembers it and applies it automatically on every future visit.
✅ Synced across devices — Your settings sync across all your Chrome instances via your Google account. Configure it once, works everywhere.
✅ Dynamic content support — BiDi handles single-page apps (React, Vue, Angular) and dynamically loaded content using MutationObserver. Works on ChatGPT, Claude, WhatsApp Web, Gmail, and more.
✅ Auto by default — Enable the "Auto by default" option to automatically apply smart RTL detection on every new website you visit — no manual setup required.
✅ Zero performance impact — Lightweight, no third-party dependencies. Written in TypeScript with performance in mind.
