RTL for Slack: Hebrew & Arabic Right-to-Left

Make Slack right-to-left for Hebrew & Arabic — fix alignment, parentheses, fonts & typing direction. Free, no account. New 2026.

The free, modern way to make Slack read right-to-left in Hebrew and Arabic. New in 2026. Slack left-aligns Hebrew and Arabic and only checks the first character of a message to guess its direction, so anything that starts with an @mention, an English word, or an emoji renders broken. RTL for Slack reads the whole message and fixes it: correct right-to-left alignment, correct parentheses, and the right font. Looking for a Slack RTL extension, Hebrew support for Slack, or a way to fix right-to-left Hebrew and Arabic on Slack? This is it — free, no account, no license key. FEATURES • Automatic right-to-left alignment for Hebrew and Arabic, based on the real message content • Live typing direction in the message box — with correct parentheses and mixed Hebrew / English / numbers • Works in channels and threads; Slack's own layout (avatars, timestamps, reactions) stays exactly where it is • Full formatting: bold, links, lists, quotes; code blocks stay left-to-right, as they should • 7 bundled Hebrew fonts and adjustable text size • Modern, lightweight, and completely free — no subscription, no activation code HOW TO USE 1. Install the extension. 2. Open or refresh app.slack.com — Hebrew and Arabic messages align correctly right away. 3. Click the extension's icon to pick a font and size. Changes apply instantly, no reload. PRIVACY Everything runs locally in your browser. No analytics, no remote code, no data collection, and no network requests while it runs. Your font and size choices are saved only on your own device and are never sent anywhere.
