I built Selaro to make things easier to find at work. It works as an auto bookmark tool based on URLs to sites that I visit. Often these are pages like confluence pages, github repos etc and bookmarking these individually is a lot of organization and effort.
The permissions needed are wide since it works based on your URLs visited. I haven't found a better workaround for this yet. The tool stores all your data locally and uses no remote database except for Auth/signup (optional).
It's not a full fledged knowledge management, but this is the scoped down MVP. Open to feedback on the product and also path forward for it.
