Find papers in your own words

Research papers and preprints, with authors, citations, funders, and open-access status.

A literature search is mostly bookkeeping: which DOI, which journal, how many citations, who paid for it, and whether anyone can read it. SpecStream reads Crossref, PubMed, Europe PMC, and arXiv, and every citation count comes with where it came from and when.

Requests to start from

Three ways to ask. Each one opens in the workspace, read into parts you can check and change.

A1
Open-access papers on microplastics in drinking water published since 2023 with at least 20 citations. Include the DOI and funders.

A2
The 25 most-cited papers on heat pumps in cold climates since 2018. Include the authors and journal.

A3
arXiv preprints about retrieval-augmented generation from the last three months. Include the abstract.

How it reads

Take A1. Before the quote, SpecStream turns it into parts you can check and change. Edit one and the request saves as a new saved version. Anything it can’t support stays visible instead of being quietly dropped.

Use them as conditions, ask for them back, or both; the field picker in the workspace shows which work where. Mark a detail required and a result needs evidence for it before it counts. Optional details can come back empty without sinking the record.

From your agent or your code

Ask for the same list from your agent or your code. Your agent sees the price before it runs, then gets every match with the details you asked for. It works within your spending limit. Connect your agent with MCP.

What it costs

You pay for the results that match, at the rate the quote shows.

Standard, $0.10 a match: up to 5 facts to check or return, with no related list.
Expanded, $0.30 a match: up to 15 facts, plus one related list, such as a company’s jobs or a creator’s posts. 10 related records a result are included, then 10¢ for each further 10.
Deep, $1 a match: anything beyond Expanded.
A person’s email, +$0.10; a phone, +$0.25 on top of the rate, when the request asks for one. A likely email counts and says likely. Rows without it pay their rate alone.
Your own list, $0.05 a row checked. A row that matches pays its rate instead.

Then what?

Open any citation count to see where it came from and when. Or export them to CSV, Excel, JSON, or HTML, share a snapshot with an expiry date, and pick the work up later from wherever you left it.
