Qalam
Arabic grammar, spelling and auto-tashkeel inside Word, Docs and browsers
Visit website →About
Qalam is an Arabic writing assistant from Mawdoo3, the company behind the largest Arabic content site on the web. It checks grammar and spelling in both Arabic and English, applies tashkeel automatically, converts numbers to written words (tafqit) for financial and legal documents, and translates in both directions.
It runs where people actually write: browser extensions for Chrome, Firefox, Safari and Edge, add-ins for Microsoft Word and Outlook, integration with Google Docs and Slides, and mobile apps for iOS, Android and Huawei. Additional tools cover OCR, plagiarism detection and sentiment analysis.
The company reports more than 400,000 users and over 18 billion words proofread, with adoption by major Arabic media outlets and publishers. A free tier is available; independent reviews put the paid plan at roughly $12 per month.

Why we picked it
Every English-language 'best writing assistant' list recommends tools that don't check Arabic grammar at all. Qalam does, and does it inside the apps Arabic writers already use — Word, Outlook, Google Docs. It's the most complete Arabic-native proofreader we found, which is why it anchors our guide to AI writing tools for Arabic.
