This seems to be another platform like ResearchGate, Academia, Google Scholar etc., just with some additional features. I would not recommend to work on this: 1. There are already too many different platforms for academic publications. 2. This is a huge work. You should not underestimate it. Besides programming manpower, you need a lot of computer storage in a cloude or somewhere else for the database, publication files etc. All this is expensive.
I would suggest to create an app that can be that handy to present reports on authentic journals and predatory journals with all relevant information. There could be categories as per quartiles, indexing, impact factors, APCs etc.
1. Citation generation capacity in multiple formats.
2. Easy ways to export papers/citations to Mendeley/Zotero library.
3. The "See first" feature to get updates from the researcher(s) a user follows ASAP.
4. Rating metrics for the journals where the paper is published, such as impact F, SJR, etc.
5. An individual page for each journal, where more information will be available, such as current aims and scopes, article processing time, APC, top-cited papers, latest papers, top authors, etc.
6. Individual pages can be created for institutions as well.
7. Please don't add the "Email updates/ Email all notifications" feature; no one likes that.
