Features
One search, six sources
Type a drug, a topic or a full question, in medicine or any other field. It goes to PubMed, Europe PMC, Semantic Scholar, ClinicalTrials.gov, OpenAlex and arXiv at once. A study found by several of them becomes one card that keeps the longest abstract and lists each source that had it. You can untick any source in the search filters. It is a studies search that replaces six separate websites, and searching is free. Spelling is corrected as you type.
Ranked by relevance, not date
Each study is compared with what you typed, then the top results are scored precisely by AI. Weaker matches wait in a collapsed section, so your time goes to the papers that answer the question. You can change the sort order at any time.
Filters that fit every field, and evidence-based filters for medicine
Every study is classified by field, publication type, approach and study design, and the filters show what fits the results, whether you are searching medicine, physics, engineering or the humanities. When medicine or life-science studies come back, evidence-based filters appear: study design from meta-analysis to case report, evidence level, subject (human, animal, in vitro, in silico) and safety or efficacy. They help when you screen studies for a systematic review or meta-analysis.
AI summaries and a data sheet
Every study gets a plain-language summary and a data sheet filled in from the abstract and, when there is one, the full text. The rows fit the field: design, sample size, evidence level, dosing and subjects for a clinical study; the matching details for other fields. A topic overview sums up the findings across the results.
Ask AI about the paper
Open a study and ask it questions. Answers come only from that paper's own text, with page citations that open the source PDF. Never a guess, never another study's data.
Full text, figures and tables: search for studies as PDF
Evidence Hub looks for a legally open-access copy of each paper first, so you can search for studies in PDF form and free. It is also a medical paid search that copes with paywalls: for a paywalled paper you already have access to, upload the PDF yourself. Every upload is checked, uploads of paywalled papers stay private to you, and a verified upload earns you points.
Pick up where you left off
A Continue card restores your last search with its filters and your place in the list, and recent searches stay one click away. Switch to the Compact view for a grid with shorter summaries. Public study pages can be found through Google and read without an account; browse studies.
Save, organize, export
Save studies into folders you create and drag them around. Export the list to CSV or RIS for your reference manager when you start writing.
Pricing
Searching, filtering, saving and exporting are free. AI work (summaries, data sheets, Ask AI, topic overviews) is paid for in points: new accounts start with a balance and you earn more by uploading a verified PDF. We're still finalizing plans and will announce changes ahead of time.
