What 'pre-check' actually means

A pre-check is the 60-second equivalent of asking a senior colleague: 'is this paper good enough to send out, or do I need another round?' Most authors never get an honest answer to that question because the people qualified to give it are too busy.

Our pre-check answers it from a title, abstract, and keywords — no full draft, no upload. The output is a calibrated Tier 1–5 verdict (Tier 1 = top venue ready; Tier 5 = needs major work) plus the detected scientific field and three identified research gaps surrounding your topic.

How the verdict is calibrated

Pre-check verdicts are not pulled from a generic LLM. The scorer is calibrated against acceptance rates from 15+ real peer review platforms — OpenReview, eLife, SciPost, PLOS ONE, BMJ Open, Nature Communications, PeerJ, F1000Research and others. A Tier 1 paper is one that, in our held-out validation set, was accepted at a top venue. A Tier 5 paper is one that was desk-rejected.

The model learns the field-specific signals editors look for: methodology coverage, novelty hedging, citation density, abstract structure, scope-versus-claim alignment.

Where to publish — matched target journals

Every pre-check run also returns a ranked shortlist of journals your manuscript fits, drawn from a 1,214-venue index built from our 33,000-paper local library. Each recommendation carries a match-score, Open-Access flag, impact-factor proxy, publisher, tier, and 2–3 similar papers we've already indexed in that venue. Beall's-archive cross-reference flags low-curation venues so authors retain agency without surprises.

No API call per request. The retrieval runs locally against a baked FTS5 + RRF index — sub-100 ms p99, $0 per query. The same panel appears at the bottom of the full AI Review.

When to use the pre-check vs the full review

The pre-check is the right call when:

  • You have a working title and abstract but the full draft isn't done yet — get a verdict before investing 80 more hours.
  • You're choosing between 2–3 target venues and want a calibrated read on which is realistic.
  • You just got an R&R and want to know whether the revision lands you above or below the bar.
  • You're a PhD student and your advisor is on sabbatical for the next month.

What the full 8-agent review adds

When the pre-check says 'almost there', upgrade to the full review for $10 or use a Researcher subscription credit. The full review uploads your PDF and runs 8 specialist agents — Methodology, Formulas, Originality, Literature, Reproducibility, Clarity, Figures, Prior Publication — plus a 12-second concurrent prior-publication check across CrossRef, arXiv, medRxiv, bioRxiv, Unpaywall, and our 900K-paper institutional library.

Full turnaround: under 15 minutes. Output: a per-agent structured report with line-level revision suggestions and a JSON export.

Frequently asked questions

Yes. Unlimited, no signup, no card. The free pre-check exists because the bottleneck in academic publishing is honest pre-submission feedback — we'd rather give that away and earn revenue from authors who go on to use the full review or publish in the open-access journal.
