Semantic Scholar remains one of the most useful free tools for navigating the scientific literature, combining a huge, well-maintained corpus with genuinely helpful AI features like TLDR summaries and citation-context highlighting. It's not trying to be a full reference manager or writing assistant, and its coverage can thin out in less mainstream or non-English venues, but for discovery, citation tracing, and quick comprehension of a paper's contribution it's hard to beat, especially given the price tag of zero and a developer-friendly API for anyone building on top of it.
