Kimi

Kimi, from Chinese lab Moonshot AI, is built around one strength: an unusually large context window. You can paste an entire book, a stack of research papers or a long contract and ask questions across all of it at once, without splitting the text into chunks.

Does Kimi support Arabic? Yes — it reads Arabic input and answers in Arabic with reasonable fluency, which is enough for summarizing and extracting from Arabic documents. The interface itself, however, is primarily Chinese with an English option, so expect to navigate menus in a language other than Arabic. For polished Arabic writing meant for publication, a model tuned on more Arabic text will read more naturally.

Best for long-document analysis, literature review and comparing several files at once. Worth knowing: it is a Chinese service, so review where your data is processed before uploading anything confidential or client-owned.
