Verdict

Choose which.

Liner

Researchers already on a Liner plan who want a criteria-based critique; the page claims "Useful comments about 70% aligned with official ICLR 2024 peer reviews", Liner's own figure.

PeerReviewAI

The manuscript you are submitting: references verified, checklist and journal instructions audited, formatting as tracked changes. $49, no verdict, no subscription.

Both

None replaces journal peer review or detects fabricated data; all find manuscript-visible problems before an editor does.

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.

What you keep

Zero Data Retention. No verdict. A full sample review published before you pay. No subscription in the months you are not submitting.

When the cheaper option is right

Liner (60 credits per review on Liner plans) if researchers already on a Liner plan who want a criteria-based critique; the page claims "Useful comments about 70% aligned with official ICLR 2024 peer reviews", Liner's own figure is all you need. PeerReviewAI for the manuscript you are submitting, when references, checklist and journal formatting all need checking.
