This is not a mockup: the text goes to the same engine behind app.lisan.com. Edit it, break it, fix it.

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.

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.

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.

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.

AI agents

Meet your agents.

Pick an agent and focus on outcomes. Each agent is tuned for one job and follows your style rules in Arabic and English: paraphrase, summarize, expand, tashkeel, humanize, detect AI text, or draft the email, on your selection or the whole document.

  • Every agent produces a suggestion you accept, copy, or ignore.
  • AI Chat takes commands scoped to the document: "translate the second paragraph".
  • Eight agents in the editor's AI panel today.

Frequently asked questions

What is WriteX?

WriteX is Lisan's AI writing assistant: an educational proofreader that checks Arabic, English, and Spanish 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 so anyone can start writing immediately. Institutional plans add style guides, team analytics, admin controls, and deployment options; contact us for a demo and pricing.

Which languages does WriteX support?

Arabic is the flagship, with the deepest coverage anywhere: spelling, grammar, morphology, semantics, tashkeel, and named entities. English includes sentence-level correction. Spanish joined through the Correcto acquisition, with purpose-built Spanish correction models.

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 to English to Spanish. One assistant that proofreads, enforces your style, and explains every correction, wherever your teams write.
