FAQ
Does Writer support .docx natively?
Yes. Open, edit, and save .docx by default. Set the default format to .docx if everyone you share with uses Word.
Can I use Word fonts (Calibri, Cambria) in Writer?
If you've installed Microsoft's fonts you'll see them. Without them, Writer maps them to similar metrics (Carlito ≈ Calibri, Caladea ≈ Cambria) so documents lay out almost identically.
Is there an AI-assist feature?
There is no built-in AI rewrite, but you can pair Writer with LanguageTool for grammar and style checks, which is also free.
