Why the price is different

Why is the price different?

Product facts verified in the code that runs the review; prices as captured.
What runs on every review

Up to four model passes: study-design detection, which selects the reporting guideline; the 16-section review; a separate compliance audit after the review is written; journal formatting as tracked changes on your .docx (a fifth pass with the ESL add-on). Plus a PubMed and Crossref lookup for every reference, with retraction screening, and a search of PubMed's roughly 40 million records for relevant uncited papers. A chat plan buys one model turn per message; the cheaper tools deliver one report.

Bundled here, priced separately elsewhere

Human pre-submission peer review starts at $272 (Enago) or $289 (AJE); journal formatting alone is $75 to $150. No AI tool in our comparison edits your Word file. Reference verification, the checklist audit and the formatting are all inside the $49.
