The institutional writing assistant
Every word you write,
checked.
WriteX proofreads across 12 error types, enforces your institution's style, explains every correction, and reports the quality numbers, in Arabic first and English alongside it. Spanish is coming soon. Save up to 45% of your writing time.
The real thing
This is the actual editor.
Not a render: a screenshot of app.lisan.com checking an Arabic sentence. Three corrections in the sidebar, the named entity ايلون مسك matched to its knowledge card, and the linguistic safety score updating live.
- Same account works in the editor, Office, and the browser extensions.
- Free to start; no card required.
Captured from app.lisan.com. The knowledge card verifies the entity, and each underline is a category.
Watch it work
Two minutes, the whole product.
The official demo: proofreading across the categories, the corrections sidebar, and the writing tools, in Arabic and English.
The tour
Proofread. Govern. Transform. Learn. Measure.
Five jobs, one assistant, everywhere your people write.
1.0 · Proofread
Twelve error types. Not just spelling.
Most checkers stop at typos. WriteX classifies errors across spelling, grammar, morphology, semantics, style, punctuation, proper names, and your own style guide, each in its own color, each counted in the sidebar.
- Arabic-first: hamza rules, case endings, morphology, and tashkeel are first-class checks, not afterthoughts.
- English sentence correction rewrites the whole sentence in one accept.
- Fix one word, one category, or press Correct All.
تحدث ايلون مسك مع المشاركون في المعرض وتم إعلان استثمارات بقيمة ثلاث وثلاثين مليار.
The same sentence Microsoft Word flags twice, WriteX flags six times, with the rule for each.
2.0 · Govern
Your institution's voice, enforced as people type.
Style guides in WriteX are not PDFs nobody reads. They are live rules: dignitary titles, editorial policy, approved terminology, date and number formats, even Quranic verse formatting, derived from a national writing standard and tuned to your organization.
- Derive from a country standard, then override anything.
- Arabic rules and English rules, managed separately.
- Assign guides to teams; violations surface as a first-class error category.
Writing style: important figures take their approved royal title.
Editorial policy: transliterations follow the institutional dictionary.
3.0 · Transform
Paraphrase, tashkeel, and smart rewriting.
Beyond fixing what is wrong, WriteX reshapes what is right: rephrase a clumsy paragraph, add full diacritics to a speech, or vowel only the ambiguous words so the text stays clean but unmistakable.
- Paraphrase keeps meaning, changes register.
- Tashkeel: full text or ambiguous words only.
- Every suggestion is accept-or-dismiss; nothing rewrites silently.

4.0 · Learn
The proofreader that teaches.
Every correction carries the rule behind it, in plain language. Writers stop repeating the same hamza mistake; teams get measurably better quarter over quarter. That is why institutions call WriteX an educational proofreader.
- Rule explanations on every card, Arabic pedagogy included.
- Word lookups: root, pattern, conjugations, synonyms, pronunciation.
- Personal error statistics show each writer their habits.
Compound numbers 13 to 19: the first part disagrees with the counted noun in gender, the second part agrees.
To go; ذهب الأثر: faded away; ذهب عقله: went mad. Conjugations, synonyms, and audio in the word panel.

Language quality you can put on a dashboard.
Linguistic safety scores, most-frequent errors, improvement over time, time saved: per writer, per team, per organization. Comms directors finally get numbers for something that used to be a feeling.
- Team and org dashboards with error-type breakdowns.
- Track improvement across quarters, not just documents.
- Export reports for management reviews.

Languages
Arabic and English today. Spanish next.
Two languages are live in the engine: Arabic with the deepest coverage anywhere, and English with whole-sentence correction. Spanish is in development on the models and team that came with the Correcto acquisition, so it arrives as native Spanish rules rather than translated English ones.
- Arabic: spelling, grammar, morphology, semantics, style, formatting, names, quotations.
- English: the same categories plus one-accept sentence rewriting.
- Spanish: coming soon, built on purpose-built Spanish correction and NER models.
Subject-verb agreement: a plural subject takes a plural verb.
Arabic and English check live in the editor today. Spanish is in development.

Frequently asked questions
What is WriteX?
WriteX is Lisan's AI writing assistant: an educational proofreader that checks Arabic and English across 12 error types, enforces institutional style guides, and reports language-quality analytics. It runs in a web editor, Microsoft Office, browser extensions, Google Docs and Gmail, Windows, and via API and SDK.
Is WriteX free?
The web editor has a free tier with a generous spelling-check allowance, so anyone can start writing immediately. Pro is $10 a month billed annually with the first month free, teams start at $15 a seat, and enterprise plans add the v3 engine, governance, and deployment options — see pricing.
Which languages does WriteX support?
Arabic and English are live today. Arabic is the flagship, with the deepest coverage anywhere: spelling, grammar, morphology, semantics, tashkeel, and named entities. English adds sentence-level correction. Spanish is coming soon, built on the purpose-built Spanish models and team from the Correcto acquisition.
How is WriteX different from a chatbot?
Chatbots rewrite text and cannot tell you why. WriteX classifies each error, shows the rule behind the fix, keeps your text under your control, and can run entirely on your own infrastructure. It is real-time, explainable, and auditable.
Can WriteX run on-premises?
Yes. WriteX deploys to the cloud, sovereign clouds, or fully on-premises, so ministries and enterprises keep every document inside their own perimeter. The engine is efficient enough that no GPU farm is required.
Every word your institution writes, checked.
Official letters to social posts, Arabic and English alike. One assistant that proofreads, enforces your style, and explains every correction, wherever your teams write.
