Reviewer3 review: what it checks, what it costs, what it leaves out.

Flags fatal flaws, hallucinated references, unsupported claims, and inconsistencies, then returns one brief report ordered by what matters most. One-Time Review $11; Researcher plan $19/month with unlimited full reviews; Teams: contact sales; a free one-time review for inviting a friend. Built from Reviewer3's published pages, quoted; we did not run manuscripts through it, and we are a competitor.

Why the price is different

What the $49 pays for.

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.

  • Not done: no manuscripts were run through Reviewer3; this page documents scope, price and stated policy, not output quality.
  • Conflict: PeerReviewAI competes with Reviewer3, so every fact is a quote with a source link, on the same eight criteria we publish for ourselves.
