Choose alphaXiv if you need free overlay for arXiv papers with public discussion/comment threads per paper; choose Connected Papers if you need visual graph of related papers built from co-citation analysis. Flocci AI Tools does not rank one above the other — it shows both feature sets side by side and lets the requirement decide.
