I’ve been testing it and it seems like a good solution for general productivity and a great option for people migrating from MS. It’s open source and cross-platform, but I just don’t see it in any conversations about office software.
For me, it’s so far leagues beyond LibreOffice. I really need something that works on my phone and syncs across devices, and allows collaboration. OnlyOffice seems to fit the bill. It’s also far more intuitive to my preferences.
I am sure that some people wouldn’t like the fact that the interface runs as a webapp, or use of Java, but it’s strange to me that it’s not usually even in the conversation.
The general idea is that you use it to take notes on research papers or websites (optionally though it’s Zotero integration), then when the time comes to write a technical paper, you can research from the comfort of your Zettelkasten, directly cite the research you took notes on and automate proper citations with BibTex, write in raw markdown if preferred, create tables natively, embed charts and graphs directly and properly track them using figure notation, do full layout templates in LaTeX, support LaTeX math equations, and a lot more.
Basically it solves the fragmentation problem researchers have had for a long time by integrating all the standards instead of trying to centrally replace them or declare them unnecessary.
