An autonomous AI agent that finds and summarises trending research papers.
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.

Screen thousands of papers down to the studies that matter
Rapidly screen a large pool of candidate papers down to a small set of core studies, so you skip the reading you do not need to do.
Search academic literature by topic and get AI-ranked results that surface the most relevant work for your research question.
Follow research trends and see what is newly published from major journals and venues, so you stay current in your field.
Browse personalised AI Feeds that adapt to your interests and research area over time.
