Wordtune
Sentence-level rewriter for English; accepts Arabic input, outputs English
Visit website →About
Wordtune, from AI21 Labs, rewrites sentences rather than whole documents: highlight a line and it offers several alternatives — more formal, more casual, shorter, longer — while keeping your meaning. It also summarizes articles and PDFs and drafts short passages. Available as a Chrome extension, a web editor and inside Word and Outlook. The free tier allows a limited number of rewrites a day; paid plans start around $7 a month.
Its multilingual support is one-directional. You can paste Arabic, Spanish, Mandarin, Hindi or Hebrew, but as the help center puts it, "the results will be in English." It is a translate-and-rewrite tool for Arabic writers moving into English, not an Arabic writing assistant.
Best for non-native English writers who want their sentences to sound natural, and for anyone who edits by ear rather than by rule.

Why we picked it
Wordtune does one thing better than the bigger suites: making a clumsy English sentence sound like a native wrote it, which is exactly what many Arabic professionals need when writing to international clients. We list it with its limit stated plainly — Arabic in, English out — so nobody buys it expecting Arabic rewrites.
