Is Apache OpenOffice a good alternative to Microsoft 365 Copilot?Comments about Apache OpenOffice as an Alternative to Microsoft 365 Copilot
Free, no ads like many other "free" programs, and open source.
10bchplsDon't use it! Apache OpenOffice is a dead project. For many years there's been no real serious updates to the project.

Comments about LibreOffice as an Alternative to Microsoft 365 Copilot
It's free and also better for some situations : Calc is better than Excel for data interpretation and format !
Really bad UI and UX, no cloud save, no collaboration tools, use this of you wanna flashback to early 2010s
LibreOffice is free and open source and also brings in free document types which are not restricted by Microsoft.
Libreoffice lacks in some point of support Microsoft only document styles but you can create fully functional documents shareable with any Microsoft office Suit.
