Feature
Arabic first.
Then the world.
Most checkers treat Arabic as an afterthought. WriteX was built for it, adds English with sentence-level correction, and now speaks Spanish through the Correcto acquisition.
Arabic
The most advanced linguistic proofreader for Arabic.
Morphology as a first-class category, hamza rules with real pedagogy, tashkeel on demand, dual-calendar dates, dignitary titles, and Quranic verse formatting. Built by the team behind 24 billion proofread words.
Hamza rule: written on waw because the damma outranks the preceding vowel.
English
Sentence-level correction, not word whack-a-mole.
English text gets grammar, punctuation, style, and named-entity checks, plus whole-sentence rewriting: five errors fixed in one accept, with a visible diff.
Subject-verb agreement: plural subject takes a plural verb.
Spanish · Correcto
WriteX now speaks Spanish.
Correcto shipped a Spanish writing assistant to the web, Chrome, and Word, powered by purpose-built Spanish models: sentence and word correction, Spanish named-entity recognition, and tone and formality technology. That team and technology now power WriteX Spanish.
- Native Spanish rules, not translated English heuristics.
- Rewrite suggestions, synonyms, and custom vocabulary.
- The same governance and analytics as Arabic and English.
Haber is impersonal when expressing existence: it stays singular.
Correcto: elevate your Spanish writing. Now part of WriteX.
Frequently asked questions
Which language is checked when a document mixes Arabic and English?
Both. The engine detects the language per passage and applies the right rule set, so bilingual documents, common in Gulf institutions, are fully covered.
What exactly did the Correcto acquisition add?
A shipped Spanish writing assistant (web app, Chrome extension, Word add-in), purpose-built Spanish correction and NER models, tone and formality technology, and the team behind them. Spanish support in WriteX is built on that foundation.
Are more languages coming?
Yes. The engine is language-modular, and the roadmap adds languages based on institutional demand.
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.
