Alnnahwi

Alnnahwi (النحوي) is a web-based Arabic grammar and spelling checker that reads the sentence context rather than matching words against a list. Paste a paragraph, a social post or a short message and it flags grammatical and spelling errors, proposes corrections, and suggests style improvements for clarity and flow. It is built for quick checks rather than long documents: short texts are free without an account, signing in raises the usage limit, and a paid tier adds capacity for heavier use. There is no browser extension or Office add-in — it is the website only. Rephrasing and summarization are not part of the product. The site cites more than 23,000 users. For an Arabic writer who wants a fast, no-subscription second look at a tweet, an email or a caption before sending it, it covers the core need. For full documents or diacritization, Qalam or Sahehly are the better fit.
