A source paper counts once, when you add its PDF. Checking it again after you edit a sentence is included.
The free start covers your first 5 source papers, with no card needed. Scholar is $9 a month ($7 a month billed annually) for 50 source papers a month. Pro is $19 a month ($15 a month billed annually) for 200 source papers a month. Prices exclude tax.
Each person on a paper needs a plan of their own. Prices exclude tax.
One source you cite, added as a PDF: a journal article, book chapter or report, or a web page or Word file saved as a PDF. It uses one from your allowance when you add it, however many of your sentences cite it, and removing it does not give it back. Two re-checks of the same paper are included.
Yes. Everyone who reviews a paper signs in with a plan of their own. An invitation gives access to the paper, not a free seat.
Everything you have already checked stays open for review. Finding quotes in new papers waits until your allowance resets at the start of the month, or until you move up a plan.
Yes. Only you and the people you invite can open it, and your files are not used to train AI models.
Yes. Export your references as RIS or BibTeX and drop the file in; entries already in your list are matched and filled in, not duplicated. You can send the list back out as RIS, BibTeX, EndNote XML or CSL JSON. For the PDFs, drag them out of your reference manager and drop them in: each one is matched to its reference by DOI or title. A direct Zotero connection is planned for Pro.
Over 10,000 journals and styles from the open Citation Style Language library, the same one Zotero and Mendeley use. If yours is missing, paste its reference rules and ResearchMaxer writes the style (paid plans), or upload a style file.
