Hello HN,
in 2017 I started a project that would become MonsterWriter. First envisioned as a semi-structured wiki it became a writing application specialized for scientific content. It is a perfect tool if you write your thesis. While it is focused on technical content, you can still see the knowledge management spirit in it.
One or two years ago, my wife joined me in my efforts and redesigned the whole project and we recently released it as MonsterWriter2.
To celebrate this milestone we are giving away free lifetime licenses for the Desktop version (till Apr 28). Just use the promo code "gu0ho4q" for a 100% discount. You can find detailed instructions here:

You can also find a short introduction video to the app on YouTube: https://www.youtube.com/watch?v=vR8i-EY_UBk
We are happy to receive any kind of feedback!
One of the most useful features is that you can just insert a doi/pubmedid/... and it will automatically fetch and format the references
Edit: One of the biggest problems with the tools for scientific writing is that the writing process if often a collaboration - one author makes a draft, distributes it, and receives comments and revisions. Currently - and sadly - I think Microsoft Word has the best solutions for commenting and revising text, although you have to keep track of multiple versions being emailed around
Edit 2: "We will use our servers to create PDF files" is a no-go for certain documents - unpublished papers are often regarded as quite sensitive
