Paper and data sources
Your assistant reads the literature where it lives.
The Scientist and the Professor's assistant search papers, preprints and open data across the sources below, often several at once, and every answer names the paper, its identifier and where it came from.
Papers and preprints
Search by question, open a paper by its arXiv id, PMID, PMC id or DOI, and follow who cites whom.
Alexandria Research Index (opens in a new tab)
Uses creditsFirecrawl's index of scientific papers across arXiv, PubMed, bioRxiv, medRxiv and more, read through our Firecrawl connection.
- Search papers and abstracts by a plain question, with author, category and date filters
- Open one paper's record by arXiv id, PMID, PMC id or DOI
- Follow the citation graph: papers that cite it, papers it cites, and close neighbours
- Read the passages of a paper's full text that answer a question
Preprints in physics, mathematics, computer science and more.
Biomedical and life-science literature, with open full text where the publisher allows it.
Scholarly works, authors, institutions and citations across every field.
The high-energy physics literature, with its citation counts and collaborations.
The data behind the papers
When a question needs a number, a structure or a dataset, the assistant goes to the record itself.
Particle properties as the Review of Particle Physics lists them.
Public LHC datasets and their records, and one file at a time onto the assistant's own computer.
Experimentally determined protein structures.
Predicted protein structures with their confidence scores.
Protein sequences and what is known about their function.
Clinical and medical research
For research questions only: never a diagnosis and never patient care.
Registered clinical trials, their status, arms and outcomes.
Medical device records.
The lists of its de-identified imaging collections.
The medical subject headings that index the literature.
Search across the web
For what is not in an index yet: a lab's page, a conference programme, a dataset's documentation.
Web research (opens in a new tab)
Uses creditsWeb search and clean reading of public pages and PDFs, through Firecrawl and our other research connections.
Scholar search (opens in a new tab)
Uses creditsScholar results through our paid research tools.
How the assistant uses them
- Every paper it cites is one it opened: a title, its authors and an identifier you can check. It never makes a reference up.
- It says which source each result came from, so you can open the record yourself.
- The free sources cost nothing. The others draw StellarFirm credits after a monthly allowance, and you can switch them off in Settings.
- Your own keys come first: connect your own Firecrawl or OpenAlex key in Integrations and those calls run on it, never on credits.
Put them to work on your question.
Hire a Scientist assistant, ask it what the literature says, and read the papers it found with their sources beside the answer.
