Honest feedback by AI · for the natural sciences

AI peer reviews run so far

Get your preprint grilled by three AI reviewers before a real editor sees it.

Your AI editor and reviewers are journal-specific, not generic.

Put that to work — aim for a higher-impact journal.

Name your target journal and PsiPi calibrates its editor and reviewer panel to that journal's actual selectivity and scope — not a one-size-fits-all bar. Use the resulting report to see exactly where your manuscript falls short, then strengthen it and aim for a higher-impact journal next.

Three AI reviewers dig in

A methodologist, a domain expert who also stress-tests every hypothesis against the data and the field's consensus, and a reproducibility nut — run live, in your browser, in parallel.

Good to know

  • PsiPi is built for the natural sciences — physics, chemistry, biology, earth & space, and adjacent fields.
  • Only submit preprints — not confidential or sensitive unpublished work — for your own research security.
  • Reviews are AI-generated, so treat them as a fast, specific starting point for revision, not a final verdict.
