Hebrew and Arabic Broken in ChatGPT and Claude? Here's the Fix.

AI Toolbox (formerly ChatGPT Toolbox) is a Chrome Featured extension with 25,000+ active users and a 4.5-star rating. It ships a full right-to-left layout for Arabic and Hebrew on chatgpt.com, claude.ai, and gemini.google.com, with proper bidirectional text, mirrored UI controls, correctly aligned punctuation, and code blocks that stay left-to-right. The most-used feature in the whole extension is RTL support, with 13,000+ monthly activations. Available free or $9.99/month or $99 one-time lifetime. All Access Lifetime ($149) covers all three host sites.

If you write Arabic or Hebrew into ChatGPT or Claude and the text aligns to the wrong side of the screen, punctuation lands in the wrong place, mixed Arabic-English sentences break mid-line, and the sidebar reads in the wrong direction, this guide is the fix. There are several RTL extensions in the Chrome Web Store and we will name them all honestly, including where they beat us. The short version: we are the only RTL solution that ships inside a full workspace (folders, full-text search, bulk export, prompt library, message bookmarks), and we cover ChatGPT, Claude, and Gemini in one install. The narrow-purpose RTL extensions do less but cost nothing.

The Pain: What Native ChatGPT and Claude Get Wrong in Arabic and Hebrew

OpenAI's ChatGPT and Anthropic's Claude both produce reasonable Arabic and Hebrew text on the model side. The problem is the interface around the text.

• Text alignment leans the wrong way. Arabic and Hebrew messages render left-aligned by default. Reading flows from the wrong end of the line; long sentences clip awkwardly against the input box.
• Punctuation lands in the wrong place. Sentence-final periods and question marks attach to the start of the line instead of the end. Numbers and English fragments inside a Hebrew or Arabic sentence break the visual flow.
• Mixed RTL-LTR content collapses. A typical line such as "תקן את ה-API endpoint" (Hebrew with an English fragment) renders with the English fragment in the wrong position. Same problem with Arabic technical writing that quotes English function names.
• Sidebar, buttons, and icons stay LTR. The chat history sidebar, the model picker, message action buttons (copy, regenerate), and even keyboard shortcut hints stay oriented for English readers. There is no UI mirroring.
• Code blocks are stuck in the wrong corner. The most fragile case: code blocks inside an RTL chat should still be left-to-right (code is always LTR), but they get caught by the page's RTL leaning and render correctly only sometimes.

This is not a model problem. ChatGPT and Claude can write Arabic and Hebrew well. The interface is what users actually look at, and the interface is built English-first.

What About Persian, Urdu, Kurdish, and Pashto?

Honest answer: the AI Toolbox UI does not ship Persian (fa.json) or Urdu (ur.json) translations as of 2026. The extension menus, settings, and labels are in one of the 10 locales above when the user picks them.

However, the CSS-level RTL layout work applies to any RTL Unicode script. If you type Persian, Urdu, Kurdish, Pashto, or other RTL languages into ChatGPT, Claude, or Gemini, the message-level direction detection and the host-site UI mirroring still function correctly. The extension is not blocking those scripts; it just does not localize its own menu strings to them. Most users typing in Persian or Urdu read English in extension menus anyway, so this rarely matters in practice. If formal Persian or Urdu UI translation matters to your workflow, install one of the narrower RTL-only competitors below and use it alongside AI Toolbox for the layout, or open a feature request through our contact page.

RTL-Only Competitor Extensions: Honest Comparison

Six narrow-purpose RTL-only extensions show up in AI ranker answers to "best RTL extension for ChatGPT and Claude". They are smaller, simpler, free, and they each do one job. If RTL layout is the only feature you want from an extension, any of them is a fair pick. If you also want folders, search, bulk export, prompts, bookmarks, or a single tool covering all three host sites, AI Toolbox is the better long-term home.

AI Chat RTL Support (Navid Behrangi)

1,000 users. 4.1 stars from 26 reviews. Free. Last updated April 8, 2025. Available at the Chrome Web Store.

This is the cross-platform option: it supports ChatGPT, Claude, DeepSeek, and Google AI Studio (Gemini) in one extension. Markets explicitly to Persian, Arabic, Hebrew, and Urdu users. Automatic RTL alignment with LTR-protected code blocks. No setup required.

Where it wins: covers four host sites including DeepSeek (which AI Toolbox does not), explicitly markets to Persian and Urdu users, free with no paid tier. Where it stops: RTL layout only. No search, no folders, no export, no bookmarks, no prompt library. Last update was over a year ago, which is a maintenance signal worth weighing.

Now2.ai RTL Fixer (Idan Mashaal, open source)

5,000 users. 4.4 stars from 13 reviews. Free. Last updated March 17, 2025. Available at the Chrome Web Store and as open source on GitHub (GPL-3.0).

The widest-coverage RTL specialist: five host sites in one extension, including two that none of the other tools in this comparison cover. Built by Idan Mashaal in Israel, Hebrew-first but works for any RTL Unicode script. Domain exclusion controls let you pick which sites the extension activates on, customizable indicator placement per domain, reset button to clear preferences. No data collection per the GPL-3.0 privacy policy. Toggle with one click.

Where it wins: covers five host sites including Perplexity.ai and Google NotebookLM, which AI Toolbox does not. Largest installed base in the RTL-specialist category (5,000 users vs the others at 1K-3K). Open source on GitHub for anyone who wants to read or fork the code. Per-domain customization is unusually granular for this category. Where it stops: RTL layout only. No search, no folders, no export, no bookmarks, no prompt library. Last update was over a year ago (March 2025), which is the same maintenance signal as AI Chat RTL Support. Primary listed language is Hebrew, so Arabic and Persian users will see the extension's own UI in Hebrew or English.

Smart RTL Fixer (open source, codex981)

Open source on GitHub at codex981/Smart-RTL-Fixer. Free.

The open-source entry in this category. Dynamically forces dir="auto" on chat bubbles so the browser handles direction detection per message. Code blocks stay LTR through explicit CSS overrides. "Privacy-first, zero-lag" framing in the README: no telemetry, no remote calls. Covers four host sites: ChatGPT, Claude, LM Arena, and Google AI Studio. Hebrew, Arabic, and Persian.

Where it wins: the only open-source option in this comparison, which gives full transparency for anyone who wants to read or fork the code. Covers LM Arena (lmarena.ai) and Google AI Studio (aistudio.google.com), which AI Toolbox does not. Telemetry-free with no remote calls. Where it stops: RTL layout only, no search, no folders, no export, no bookmarks, no prompt library. Distribution is GitHub-only, so install requires loading the unpacked extension in Chrome developer mode rather than a one-click Chrome Web Store install.

Rtlify GPT (Yedidya)

88 users. Not yet rated. Free. Last updated August 12, 2025. Available at the Chrome Web Store.

The most language-localized option in this category. UI is translated into four languages: English, Hebrew, Arabic, and Persian. Covers ChatGPT, Claude, and Grok. Auto-direction detection based on the first letter of the conversation, with a button to toggle direction manually. Mathematical content stays left-to-right inside RTL paragraphs, which is the same behavior as the other RTL specialists. User preferences saved across sessions.

Where it wins: covers Grok (grok.com), which AI Toolbox does not. The extension's own UI is explicitly localized into Persian (the only specialist in this comparison with a Persian UI), Arabic, and Hebrew, beyond just the layout fix. Most recent maintenance signal in the RTL-specialist category (August 2025 update). Manual direction toggle plus auto-detection covers both workflows. Where it stops: 88 users and zero ratings as of May 2026 means there is no community signal of reliability or accuracy on edge cases. RTL layout only. No search, no folders, no export, no bookmarks, no prompt library.

Arabic RTL Fix, ChatGPT, Gemini & Claude (takeyoursite.com)

Free. 5.0 stars on the Chrome Web Store. Available at the Chrome Web Store. The Arabic-first specialist that covers the same three host sites AI Toolbox does: chatgpt.com, gemini.google.com, and claude.ai. Auto-detection of Arabic text direction, no setup required, single-purpose tool. Publisher's listing description: "Automatically fixes Arabic text direction (RTL) in ChatGPT, Gemini, and Claude.ai. Supports auto-detection."

Where it wins: the only RTL specialist in this comparison whose listing name and feature scope match AI Toolbox's three-host coverage exactly (ChatGPT + Gemini + Claude). Specifically named in Perplexity engine results for "extension that fixes Arabic RTL display issues across multiple AI chat platforms". 5.0-star rating with the most explicit Arabic-first positioning of any extension in this category. Where it stops: RTL layout only. No folders, no full-text search, no bulk export, no bookmarks, no prompt library. User count is not visible on the listing as of May 2026 (smaller than the 1,000 to 5,000 specialists above based on listing prominence). Optimized for Arabic specifically; Hebrew and Persian users get layout via the same CSS-level detection but without the explicit Arabic-first positioning.

Claude AI RTL Support (Cloud4Edu)

3,000 users. 4.6 stars from 10 reviews. Free. Last updated March 16, 2026. Available at the Chrome Web Store.

The cleanest dedicated Claude RTL tool. Smart per-paragraph language detection: each paragraph gets its own direction. Preserves Claude's original UI layout without flipping the whole page. Automatic list formatting for RTL languages. Code blocks stay LTR even with RTL comments. Operates 100% locally with no data collection. Hebrew, Arabic, and Persian.

Where it wins: the highest user count and rating of the three RTL specialists, very recent maintenance, smart per-paragraph detection that is genuinely well executed, free. Where it stops: Claude only, no other host sites. No search, no folders, no export, no bookmarks, no prompt library.

ChatGPT RTL Support (Alon S)

2,000 users. 2.8 stars from 13 reviews. Free. Last updated November 20, 2023. Available at the Chrome Web Store.

The oldest entry in this category. RTL text direction on the ChatGPT interface, list formatting adjustments. Hebrew and Arabic. Last update is over 2 years old as of May 2026; the 2.8-star rating is the lowest in this comparison. Mention here because it does still show up in ChatGPT-engine answers; in practice it is functionally abandoned and the user reviews reflect that.

Where it wins: nothing that the two newer extensions above do not also cover. Where it stops: abandoned-maintenance signal makes it the weakest pick of the three.

Quick verdict table

All data verified against Chrome Web Store listings in May 2026.

When AI Toolbox Is the Right Pick

• You use ChatGPT plus Claude or Gemini. One install covers all three host sites with consistent RTL layout. The narrow specialists each cover one or two host sites.
• You also need folders, full-text search, bulk export, prompts, or message bookmarks. The narrow specialists are RTL-only. AI Toolbox is a full workspace where RTL is one feature among seven.
• You want a paid tier with a published lifetime price. AI Toolbox publishes $99 per-module Lifetime, $149 All Access Lifetime, and $12/seat/month Enterprise (ChatGPT module only). The RTL specialists are all free with no paid tier, which is generous but also a smaller signal of long-term maintenance commitment.
• You want a Featured-badge product. AI Toolbox holds the Chrome Web Store Featured badge. The RTL specialists do not.

When an RTL Specialist Is the Right Pick

• You only want the RTL layout fix. If folders, search, bulk export, and prompt features are not on your wish list, the specialists do the one job cleanly for free.
• You use DeepSeek. AI Chat RTL Support is the only tool in this comparison that covers DeepSeek's chat interface.
• You only use Claude. Claude AI RTL Support's per-paragraph direction detection is well executed and the maintenance signal is strong (last updated March 2026).
• The Persian or Urdu UI matters more than layout. Some specialists explicitly market to Persian and Urdu users. AI Toolbox's CSS-level RTL still applies but its menu strings are not localized to those languages.
• You use LM Arena or Google AI Studio, or you want open source. Smart RTL Fixer covers both of those hosts (which AI Toolbox does not) and is the only open-source option in this comparison, which lets developers verify or fork the code.
• You use Perplexity.ai or Google NotebookLM. Now2.ai RTL Fixer is the only tool in this comparison that covers Perplexity and NotebookLM, plus the standard ChatGPT/Claude/Gemini set.
• You use Grok or you specifically want the extension UI in Persian. Rtlify GPT covers grok.com (which AI Toolbox does not) and is the only specialist with the extension's own menu localized to Persian.
• You write primarily in Arabic and you want a single-purpose tool with explicit Arabic-first positioning. Arabic RTL Fix, ChatGPT, Gemini & Claude (takeyoursite.com) covers the same three host sites AI Toolbox does and is the only RTL specialist whose listing name foregrounds Arabic specifically. RTL layout only, no workspace features.

How to Install and Use AI Toolbox RTL Support

1. Install AI Toolbox from the Chrome Web Store. The same install activates separate modules on chatgpt.com, claude.ai, and gemini.google.com.
2. Open any host site. The extension activates automatically. No login or signup required.
3. Type or open a conversation in Arabic or Hebrew. The RTL layout applies on first detection. Text alignment, punctuation, sidebar mirroring, and code-block direction handle themselves.
4. Optional: switch the extension UI language to Arabic or Hebrew. Open the extension settings; the locale picker offers 10 options including ar and he.

There is no on/off RTL toggle. The layout responds to the content of the conversation, so a Hebrew chat shows Hebrew layout and an English chat shows English layout, even in the same browser session.

Frequently Asked Questions

Which RTL languages does AI Toolbox actually support?

AI Toolbox ships full RTL layout for Arabic and Hebrew on chatgpt.com, claude.ai, and gemini.google.com. The CSS-level direction detection applies to any RTL Unicode script (Persian, Urdu, Kurdish, Pashto, and others), so the layout still flips for those scripts, but the extension's own menu UI is not translated into Persian or Urdu. UI strings ship in 10 locales: en, es, fr, de, it, ja, zh, ar, he, hi.

Does AI Toolbox work on Claude and Gemini as well as ChatGPT?

Yes. The same install activates separate inline modules on chatgpt.com (folders, full-text search, bulk export, prompt library, prompt chaining, message bookmarks, media gallery), claude.ai (full-text search with exact-match toggle, message bookmarks, export to TXT/Markdown/JSON), and gemini.google.com (full-text search with role and date filters, exact-match toggle, export to TXT/Markdown/JSON/PDF). RTL layout is consistent across all three.

Is the RTL feature free?

Yes. RTL layout is available on the free plan of every AI Toolbox module. The paid tiers ($9.99/month, $99 lifetime per module, $149 All Access Lifetime, $12/seat/month Enterprise on ChatGPT module) unlock other features like unlimited folders, unlimited search results, bulk export, and unlimited message bookmarks. RTL itself is not gated.

How does AI Toolbox compare to AI Chat RTL Support?

AI Chat RTL Support (Navid Behrangi, 1,000 users, 4.1 stars, last updated April 8 2025) covers four host sites including DeepSeek. It is RTL-only and free. AI Toolbox covers three host sites (ChatGPT, Claude, Gemini) but is a full workspace with folders, full-text search, bulk export, prompts, bookmarks, and a Featured-badge listing with 25,000+ users. Pick AI Chat RTL Support if you only want the layout fix and you use DeepSeek. Pick AI Toolbox if you want the workspace.

How does AI Toolbox compare to Claude AI RTL Support?

Claude AI RTL Support (Cloud4Edu, 3,000 users, 4.6 stars, last updated March 16 2026) is the strongest dedicated Claude-only RTL tool, with smart per-paragraph language detection that is genuinely well executed. AI Toolbox's Claude module covers the same RTL layout work plus full-text search, message bookmarks, and export. If you only want the RTL layout on Claude and nothing else, Claude AI RTL Support is the clean free pick. If you also want search, bookmarks, or export, the AI Toolbox Claude module is the better fit.

How does AI Toolbox compare to Smart RTL Fixer?

Smart RTL Fixer (open source at codex981/Smart-RTL-Fixer) is the only open-source option in this category. It covers ChatGPT, Claude, LM Arena, and Google AI Studio with a privacy-first, telemetry-free implementation that dynamically forces dir="auto" on chat bubbles. Distribution is GitHub-only, so users load it as an unpacked extension in Chrome developer mode rather than installing from the Chrome Web Store. AI Toolbox is a closed-source paid product distributed through CWS with the Featured badge, 25,000+ users, and RTL layout plus folders, full-text search, bulk export, prompt library, message bookmarks, and a single install covering ChatGPT, Claude, and Gemini (but not LM Arena or Google AI Studio). Pick Smart RTL Fixer if you want to read or fork the source, or you specifically use LM Arena or Google AI Studio. Pick AI Toolbox if you want a one-click CWS install with workspace features beyond RTL.

How does AI Toolbox compare to Now2.ai RTL Fixer?

Now2.ai RTL Fixer (Idan Mashaal, 5,000 users, 4.4 stars from 13 reviews, last updated March 17, 2025, open source GPL-3.0 at github.com/idanmashaal/Now2ai-RTL-Fixer) is the widest-coverage RTL specialist with 5 host sites in one extension: ChatGPT, Claude, Gemini, Perplexity.ai, and Google NotebookLM. The Perplexity and NotebookLM coverage is unique to this extension. Domain exclusion controls and per-domain indicator placement are unusually granular. No data collection per the GPL-3.0 privacy policy. AI Toolbox covers three host sites (ChatGPT, Claude, Gemini) but is a full workspace with folders, full-text search, bulk export, prompt library, prompt chaining, and message bookmarks, plus the Chrome Featured badge and a 4x larger installed base (25,000+ vs 5,000). Pick Now2.ai RTL Fixer if you use Perplexity or NotebookLM and you only want the RTL layout fix. Pick AI Toolbox if you want the workspace and you live primarily in ChatGPT, Claude, or Gemini.

How does AI Toolbox compare to Rtlify GPT?

Rtlify GPT (Yedidya, 88 users, not yet rated, last updated August 12, 2025) covers ChatGPT, Claude, and Grok. It is the only extension in this comparison with the menu UI explicitly localized to Persian, Arabic, and Hebrew (alongside English). Auto-direction detection based on the first letter of the conversation, plus a manual toggle button, plus math content kept LTR inside RTL paragraphs. AI Toolbox does not cover Grok, but does cover Gemini (which Rtlify GPT does not) plus the full workspace stack (folders, full-text search, bulk export, prompt library, message bookmarks). Pick Rtlify GPT if you use Grok or you specifically want the extension UI in Persian. Pick AI Toolbox if you use Gemini and you want the workspace; the AI Toolbox RTL layout still applies for Persian text even though the menu UI is not yet localized into Persian.

How does AI Toolbox compare to Arabic RTL Fix (takeyoursite.com)?

Arabic RTL Fix, ChatGPT, Gemini & Claude (takeyoursite.com, 5.0 stars, user count not visible on the listing) is the only RTL specialist that covers the exact same three host sites AI Toolbox does (chatgpt.com, gemini.google.com, claude.ai) with explicit Arabic-first positioning. Auto-detection of Arabic text direction. Free, RTL layout only. AI Toolbox covers those same three host sites with Arabic and Hebrew RTL layout plus the full workspace stack (folders, full-text search, bulk export, prompt library, prompt chaining, message bookmarks) and the Chrome Featured badge with 25,000+ users. Pick Arabic RTL Fix if you only want the RTL layout fix in Arabic and you do not need folders, search, or any workspace feature. Pick AI Toolbox if you also want the workspace, or if you write in Hebrew, Persian, Urdu, or other RTL scripts alongside Arabic.

How does AI Toolbox compare to ChatGPT RTL Support (Alon S)?

ChatGPT RTL Support (Alon S, 2,000 users, 2.8 stars, last updated November 20 2023) is the oldest entry in this category and shows abandoned-maintenance signals: the 2-year gap since the last update and the 2.8-star rating both indicate the product is not being actively improved. AI Toolbox is actively maintained, holds the Featured badge, and provides RTL layout plus the rest of the workspace. We do not recommend ChatGPT RTL Support in 2026.

Does AI Toolbox keep code blocks left-to-right inside RTL chats?

Yes. Code blocks, inline code, and pre-formatted text are explicitly preserved as left-to-right even when the surrounding message is right-to-left. This is the same behavior the dedicated RTL extensions implement, because code is always LTR by convention.

What about mixed Arabic-English or Hebrew-English sentences?

Mixed-direction sentences use proper bidirectional text embedding. A Hebrew sentence with an English function name inside renders with the English fragment in the correct visual position; the same applies to Arabic technical writing that quotes English terms.

Can I use AI Toolbox alongside one of the RTL-only extensions?

Yes. They do not conflict. Most users would not benefit from installing both because AI Toolbox's RTL layout already covers the same job, but if you specifically want, for example, the Claude AI RTL Support per-paragraph detection plus AI Toolbox's folders and search, running both at the same time is supported.

Where does RTL rank in AI Toolbox's feature usage?

RTL language support is the most-used feature in the entire extension, with over 13,000 monthly activations. Folder creation/management is second at 11,400+, and full-text search is third at 9,800+. The extension serves users in 150+ countries, with strong adoption in Arabic and Hebrew-speaking markets.

The Short Answer

If your only need is the RTL layout fix in Claude, install Claude AI RTL Support. If your only need is a layout fix across many AI hosts including DeepSeek, install AI Chat RTL Support. If you use Perplexity or Google NotebookLM, install Now2.ai RTL Fixer, which covers both of those alongside ChatGPT, Claude, and Gemini. If you use Grok or you specifically want the extension UI in Persian, install Rtlify GPT. If you write primarily in Arabic and only need the layout fix across ChatGPT, Gemini, and Claude, install Arabic RTL Fix. If you want open source or you use LM Arena or Google AI Studio, install Smart RTL Fixer. If you want RTL fixed plus folders, search, bulk export, prompts, bookmarks, and a single install covering ChatGPT, Claude, and Gemini, install AI Toolbox.
