The mistakes everyone makes, fixed where you type.

Hamza on or under the alif, ta marbuta or ha, alif maqsura or ya: native writers and learners trip on the same handful of rules. ضاد fixes them live and shows you why, so you stop making them.

Fixes as you type, in every app

WhatsApp, Mail, Notes and anywhere else you write. Don't like a fix? One backspace brings back what you typed.

Every fix explained

When a word could go either way, like علي or على, ضاد suggests and you choose. Long-press to read the rule.

Grammar too, on your device PRO

An AI model inside the app catches what spelling rules can't: plurals, the predicate of كان and إنّ, the five verbs after لم and لن, numbers and their nouns. Downloaded once (about 530 MB); needs iOS 26.4 and 4 GB of memory.

المعلمين ← المعلمون · جمع المذكر السالم
كان الجو جميل ← جميلًا · خبر كان
لم يذهبون ← لم يذهبوا · الأفعال الخمسة

Questions

ضاد (Daad) is an Arabic spell-checking keyboard and proofreader for iPhone and iPad, built natively in Swift.

Is ضاد free?

The keyboard, live corrections, suggestions, your personal dictionary and full checks of everyday messages are free. ضاد Pro is an optional one-time purchase that adds the grammar check, tashkeel, unlimited checks, weekly lessons, themes and iCloud dictionary sync. Try it free for 7 days; it never turns into a subscription.

Does ضاد read what I type?

Only on your device, to suggest corrections. Nothing you type is sent anywhere, stored by us, or used for training. The keyboard doesn't need Full Access; if you turn it on, it's used only for haptics and to save the words you add to your dictionary.

I'm learning Arabic. Is ضاد for me?

Yes. Every correction comes with the rule in one line, tashkeel shows how words are pronounced, and the weekly lessons focus on the mistakes you actually make. Note that the app's interface is in Arabic.

Will it change my dialect into formal Arabic?

No. ضاد recognises Egyptian and Gulf messages and keeps to general spelling there, so words like ده, وش and عشان stay as you wrote them. You can also turn on dialect mode with a long-press on the space bar.

How accurate are the grammar check and tashkeel?

They're AI suggestions, so review them before relying on them. The grammar check only shows corrections it can explain, and nothing is applied unless you accept it. Tashkeel never changes your letters; most of its slips are in word endings.

ضاد uses open data, models and software, credited in the app under Settings → Sources and licences. Gemma is provided under and subject to the Gemma Terms of Use found at ai.google.dev/gemma/terms.
