Where AI Falls Short in Arabic Marketing Copy, and How to Check It

An AI tool can turn an English campaign brief into Arabic captions, ad variants and landing-page copy in minutes. The output often looks fluent at a glance. The problems show up later: a Saudi ad that ends in an Egyptian word, a counted noun with the wrong number form, an English idiom rendered word for word, or a headline whose letters come apart once it is placed in the design file.

This guide is a quality check for that output. It does not rank AI models on Arabic, since no single published benchmark settles that for marketing copy. It lists the failure points a reviewer should look for, with examples written by RX for illustration, and ends with a checklist your team can run before anything is published. If you are still setting up the rules your AI tools follow, start with turning brand guidelines into rules AI tools can follow; this article picks up after the draft exists.

1. Register: decide before anyone writes a prompt

In our experience, the most frequent problem is not a grammar mistake. It is a draft that does not commit to one level of Arabic. Modern Standard Arabic (MSA, fusha) suits company profiles, websites, tenders, formal LinkedIn posts and anything read across several countries. Dialect suits short social captions, reels, WhatsApp replies and ads aimed at one market. Both are legitimate. Mixing them in one sentence is a mistake.

“Gulf Arabic” is also not one dialect. Najdi, Hijazi and Emirati speech differ in everyday words, and a local reader is likely to notice when an ad aimed at Jeddah uses a Riyadh word, or when a non-Saudi writer imitates Saudi speech badly. Egyptian Arabic is widely understood across the region, largely through film and television, but an Egyptian word in a Saudi ad can still tell the reader the brand is not local. The forms below are typical everyday choices; usage varies by city and generation, which is why the native reviewer has the final say.

A typical mixed draft reads like this: نحن نقدم أفضل خدمات الصيانة، وعشان كذا عملاؤنا يرجعون لنا. It opens in formal MSA and finishes in Saudi colloquial. Pick one:

• MSA: نقدم أفضل خدمات الصيانة، ولهذا يعود إلينا عملاؤنا.
• Saudi colloquial: نقدم لك أفضل صيانة، وعشان كذا العملاء دايم يرجعون لنا.

The fix is upstream. Every brief should state the register, the market and, for dialect, the city or region. Your reviewer for a dialect piece should be a native speaker of that dialect, not simply “someone who speaks Arabic”.

2. Grammar a fluent reader catches in seconds

Arabic marks gender and number on verbs, adjectives and numbers. A draft can be fluent and still get these wrong, and a native reader will usually notice. Check these points on every piece.

Who are you talking to?

A call to action is gendered. سجّل الآن addresses one man, سجّلي الآن one woman, and سجّلوا الآن a group. Many brands default to the masculine singular or the plural. That is a choice, but it should be made once and written into your guidelines; what Arabic brand guidelines should include covers where it belongs. A campaign aimed at women that addresses the reader in the masculine reads as careless, and AI drafts can switch form from one variant to the next.

Plurals of things take feminine singular agreement

In MSA, a plural of non-human nouns normally takes a feminine singular adjective or verb: المنتجات متوفرة الآن and الخدمات التي نقدمها, not المنتجات متوفرين or الخدمات اللي نقدمهم. The masculine plural comes from colloquial speech and looks wrong in formal copy.

Counted nouns

Numbers three to ten take the opposite gender of the noun they count, judged by its singular form. سنة is feminine, so a warranty line should read ضمان لمدة ثلاث سنوات, not ثلاثة سنوات. With a masculine noun it flips: ثلاثة أعوام. Warranty periods, years of experience and branch counts are lines buyers tend to read closely, and the error is easy to miss when the number is written as a digit and only surfaces in a voice-over.

Case endings in formal copy

Most marketing copy is written without full vowel marks, but some forms still show. In MSA, نقدم حلولاً متكاملة is correct; نقدم حلول متكاملة is the colloquial habit. A company profile or tender document should use the correct form.

Arabic punctuation

Arabic uses its own comma (،), semicolon (؛) and question mark (؟). A Latin comma or question mark inside Arabic text, or a question mark that ends up on the left of a right-to-left line, often suggests the copy was pasted rather than written.

3. Literal translations and false friends

When the source brief is in English, AI drafts tend to keep the English structure and idioms. Some calques are now accepted in Arabic business writing; فكّر خارج الصندوق is understood, though tired. Others make no sense or say something else entirely.

A useful habit: give the AI tool the intent of a line (“tell the buyer the quotation costs nothing and comes within a day”) rather than the English line itself, and ask for Arabic written for that market. Then compare against your approved terminology list, so a product category, service name or job title is the same word in every post.

4. Errors that only appear in the design file

Copy that is correct in a document can break when it is placed in a design, a video subtitle or a web page (for bilingual sites, see how to structure an Arabic and English website). These faults are not the AI’s doing, but AI increases the volume of Arabic going into templates, so they are likely to surface more often. Check the final export, not the text file.

• Disconnected or reversed letters. Arabic letters join within a word. The W3C’s Arabic and Persian Layout Requirements (a Group Draft Note, October 2025) notes that “letters of each word join together whenever possible”. If a headline shows separate letters, or the word order reads backwards, the software or font is not shaping Arabic. In Adobe InDesign, for example, Adobe’s help page describes setting up World-Ready composers for Arabic; check the current steps for your version.
• Effects applied letter by letter. The same W3C document says styling or borders applied to individual letters should not break a letter’s joining with its neighbours. Animated “letter-by-letter” reveals in motion templates can cause exactly this.
• Mixed Arabic and English lines. Phone numbers, prices, model codes and brand names inside an Arabic sentence follow the Unicode bidirectional algorithm. W3C notes that numbers have weak directionality and that signs such as currency or degree symbols next to them are likely to be treated as part of the number, so their position is easy to get wrong. Read every line that mixes scripts in the exported file, for example a price line such as السعر 1,500 ريال or a hypothetical model name such as جهاز X200 الجديد.
• Digits. Western digits (123) and Arabic-Indic digits (١٢٣) are both in use; W3C lists Arabic-Indic digits for the Eastern Arab region, including Egypt and Saudi Arabia. Choose one set per brand and channel, write it into the guidelines, and check that a draft has not mixed them.
• Stretched words. Justified Arabic can be stretched with kashida, but W3C cautions that excessive or very long kashida “results in uneven color”. Right-aligned, unjustified text is often the safer choice in social designs.
• Web pages. For an Arabic page, W3C recommends setting the right-to-left direction attribute (dir=”rtl”) on the html element rather than relying on CSS, and using start and end rather than left and right in styles, so the layout flips correctly.

Paid platforms also check text quality. Google Ads’ editorial policy does not allow ads that “don’t use commonly accepted spelling or grammar”, or punctuation and symbols “that aren’t used correctly or for their intended purpose”. Broken Arabic can cost you approvals as well as credibility.

5. Cultural and regulatory misfires

Some errors are not linguistic. They are about who is speaking, what is shown and which market the copy thinks it is in.

Dialect and identity in the UAE

In September 2026 the UAE’s National Media Authority said it has objected to “non-Emiratis using a broken or exaggerated Emirati dialect to sell products”, according to Khaleej Times (30 September 2026). The same report says the restriction targets ads and paid content rather than everyday social settings, that Emirati national dress (it names the kandura) is reserved for Emirati citizens in commercial and promotional content, and that using AI to generate images or videos of national symbols or public figures without prior official approval violates the Media Content Standards. It also says individuals publishing advertising content online, paid or unpaid, need an advertising permit.

Earlier coverage framed the policy more broadly. The National (25 April 2025, updated 2 May 2025) reported that the Federal National Council had been told of a regulatory policy to stop non-citizens using the Emirati dialect and national dress in social media advertising by content creators and advertisers, and said it would apply once brought into law. The two reports differ: the earlier one covers any use of the dialect by non-citizens in social media ads and describes rules still to be introduced, while the later one speaks of broken or exaggerated dialect used to sell products and adds AI imagery. Check the current Media Content Standards and the authority’s own guidance before a campaign, and take legal advice where it matters. This is not legal advice.

The practical rule for AI work: do not ask a tool to “write it in Emirati dialect” and publish the result with a non-Emirati voice or presenter. Use MSA or a neutral register, or have Emirati talent and a native reviewer for dialect content. We would treat AI image prompts involving national symbols, public figures or national dress as off limits without official clearance.

Wrong market details

• A Saudi ad quoting prices in dirhams, or an Egyptian post in riyals.
• National Day, school calendar or weekend references copied from another country.
• Place names, phone formats and delivery promises that belong to a different market.

Tone around religion and occasions

Religious phrases and occasions such as Ramadan and Eid appear in a lot of regional marketing. AI drafts can attach them to hard-sell lines in ways a local reader finds out of place. A native reviewer should read every seasonal piece with that in mind, and religious text should not be used as a sales hook.

6. The review checklist

Run this on every AI-drafted Arabic piece before it goes to the client or manager for approval. It fits alongside the approval gates in an AI-assisted content workflow; this list is what the language gate actually checks.

1. Register: the piece uses the register and dialect named in the brief, from first word to last.
2. Reviewer: a native speaker of that dialect (or a strong MSA editor for formal pieces) has read it aloud.
3. Addressee: the gender and number of “you” are consistent and match the audience.
4. Agreement: adjectives, verbs and counted nouns agree; numbers three to ten are checked.
5. Idioms: no English idiom survives word for word; false friends such as اقتباس for “quote” are caught.
6. Terms: product, service and job-title terms match the approved list.
7. Punctuation and digits: Arabic comma and question mark used; one digit set throughout.
8. Final file: letters join, nothing is reversed, mixed-script lines read correctly in the exported design, video and web page.
9. Market: currency, dates, places and occasions belong to the target country.
10. Rules: no dialect impersonation, national symbols or national dress that breach local media rules; UAE pieces checked against current standards and permit requirements.
11. Platform: ad text meets the platform’s editorial policy before submission.

AI drafting is useful for Arabic content when the brief fixes the register and a native reader checks the output in its final form. Without those two steps, faster drafting is likely to mean more errors going out. A practical first step: take the last ten Arabic pieces you published, run each through the checklist in its final exported form, and note which item fails most often. That item tells you whether to fix the brief, the term list or the reviewer.
