   LibreOffice vs Microsoft 365 Copilot Comments

   Top Positive Comment by social-remodeler · Oct 2, 2024

   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.

   Really bad UI and UX, no cloud save, no collaboration tools, use this of you wanna flashback to early 2010s

   Positive comment by Guest · Aug 30, 2024

   I have it on my laptop and like it's gui and similarities to Ms office so you don't have to search too hard through menus to find what you're looking to do. 4.8/5.

   ONLYOFFICE vs Microsoft 365 Copilot Comments

   Top Positive Comment by maurosoft391 · Jan 5, 2024

   ONLYOFFICE is a good alternative to MS office (365). the UI is similar, it's as fast as MS office and it's free and open-source. the formatting is not a problem than the messed up problems in LibreOffice. and the fonts that LibreOffice messes up are shown correctly.

   Positive comment by social-remodeler · Oct 2, 2024

   It is not proprietary software.

   Positive comment by nguyenkhoi-luong-56 · Jun 27, 2024

   It's free and open source software. Compatible with most Microsoft Office documents. Doesn't track you at all.

   CryptPad vs Microsoft 365 Copilot Comments

   Positive comment by Shaz Shah · Jul 28, 2025

   I like Cryptpad as an alternative to M365, where it allows you to self-host your own office suite, which looks like an instance of OnlyOffice hosted in the "cloud" while respecting E2EE and is open source. If you'd rather use the cloud than self-host you can use a public instance or a paid plan for hosting and storage.

   Positive comment by kaspian · Jan 30, 2023

   Great thing to selfhost, it uses E2EE

   Calligra Suite vs Microsoft 365 Copilot Comments

   Comment by Shaz Shah · Jul 28, 2025

   Calligra Suite's interface kinda resembles iWork (is it still called that?), which would come as a shock to those coming from Office. Unfortunately, I didn't have a stable experience using it on my device running Zorin OS. It also lacks collaborative features.

   SoftMaker FreeOffice vs Microsoft 365 Copilot Comments

   Positive comment by Entterprice · Oct 12, 2026

   FreeOffice for students, bootstrapped startups, and casual home users — free, light, offline, good enough. Microsoft 365 with Copilot for growth-stage teams where collaboration and AI actually save time. Fintechs must use Microsoft 365, ideally Business Premium plus Copilot — audit trails, DLP, data residency, and permission-bound AI aren't optional. FreeOffice stays personal, never production in finance.

   Positive comment by spqe · Mar 8, 2023

   Quite lightweight in comparison with alternatives, a good interface.

   Negative comment by kaspian · Jan 30, 2023

   Misleading name, it isn't free.

    MobiOffice vs Microsoft 365 Copilot Comments

    Negative comment by maurosoft391 · Jun 20, 2024

    the free version is too limited with less features annoying watermarks on PDFs. if you want the complete version with all of its features, it's expensive.

    Positive comment by designexperience7 · Mar 18, 2023

    Well, it's even better.... It has more features; such as conditional formatting, sheet protection, data validation, and lots more!

    Positive comment by KostantinStambolov · Jun 1, 2017

    This is the only real alternative to Office 365. It's the most feature rich complete office solution for Documents, Spreadsheets, Presentations and PDF files. You can work on any device and sync all you work with ease.
