I'm not really sure that I see an "app chaos problem". For each company/job workflow that I've encountered, there are a set of apps that solve for the specific use-case.
For example as the head of devrel at the last company that I worked for, we used Atlassian products for internal documentation and work tracking, we used Google's docs and sheets for collaborative writing with external teams, and we used github and markdown for external docs building. It's all text, but the work flows were different, had different needs (like permissions), and ultimately we found the right tools for the job.
I wish you luck with this endeavor, but I hope that your looking for a specific problem. To solve that isn't "app chaos".
Exactly, my company have a similar setup and I don't think people have trouble figuring out which tool to use or how they work with each other. Nino seems to try to solve a problem that hardly exist.
