GoatStack.AI is an AI agent for keeping up with machine-learning research. Instead of manually trawling arXiv, PubMed and OpenReview, it discovers trending papers, summarises them into digestible briefings, and surfaces the insights that matter, so you can track the field without drowning in PDFs.
An agent continuously scans research repositories to find the papers gaining attention, so you see what is hot without searching yourself.
Long, technical papers are condensed into short, readable summaries you can skim in minutes before deciding what to read in full.
Coverage reaches across AI pre-prints and biomedical literature, pulling from sources like arXiv, PubMed and OpenReview.
Rather than a raw feed, the tool highlights the key ideas and takeaways from each paper so you can follow the field's direction.

Semantic Scholar is a free, non-commercial academic search engine built by the Allen Institute for AI (Ai2). It indexes more than 240 million papers from every field of science and uses machine learning to extract meaning from abstracts, citations, figures and tables, so researchers find relevant work faster than with keyword-only search.
