Peer-reviewed preprints

Get your preprint peer‑reviewed. Then publish it.

Upload your paper. We match it with the experts best placed to judge it, run a double-blind review, and once they sign off on your revision you publish it as a peer-reviewed preprint — in weeks, not months.

Free to upload · Pay only when reviews are delivered · Free to publish · You keep your copyright

Why this exists

Peer review is slow, unpaid, and a lottery.

Researchers write the papers, review each other's work and serve on editorial boards for free — then wait months for a verdict that depends more on who reviewed the paper than on what it says.

3–6 mo for a single round of journal review. Several rounds can take over a year.
$0 paid to the reviewers who provide the single most important quality check.
$2K–11K in article processing charges to publish open access with a legacy publisher.
10,000+ papers retracted in 2023 alone — a record that review did not prevent.

How it works

From upload to published, in five steps.

Software does the legwork — reading the paper, finding reviewers, chasing replies. The judgment stays with human experts.

  1. 01

    Upload your paper

    Drop a PDF or Word file. We read it and pull out the specific questions that need an expert eye. Free, and nothing is sent to anyone yet.

  2. 02

    Approve your reviewers

    We search the global publication record for the researchers best placed to judge each question and show you an anonymized shortlist. Nothing reaches a reviewer without your approval.

  3. 03

    Double-blind review

    Each reviewer gets a focused request anchored on the passages that matter, and comments directly on your paper. You and they stay anonymous to each other, so feedback stays candid.

  4. 04

    Revise with the same reviewers

    Upload a revised version from your author space. The reviewers who read the first draft check it against their own comments and say whether it is ready.

  5. 05

    Publish when they sign off

    Once enough reviewers endorse the revision — at least two, and none saying “not yet” — you get a Publish button. You decide if and when. It goes live on the Unjournal preprint journal, with its reviews alongside — and, like any preprint, the copyright stays with you.

A new kind of paper

Between a preprint and a journal article.

A peer-reviewed preprint has been through real expert review and revision, without the year-long wait or the gatekeeping. Readers see the paper and the reviews behind it.

For reviewers

A focused ask, not a weekend gone.

If we contact you, it is because your own work sits right where a paper needs an expert opinion — and because its author asked for independent review.

Pricing

Pay for the review. Never to publish.

No subscription, no article processing charge. You pay once for the review, and only when the reviews are in.

Step 1

Upload & reviewer shortlist

Free

See who we would invite before you commit to anything.

Step 2

Double-blind review

Pay on delivery

Nothing to pay upfront. You are charged once the reviews are delivered, with a money-back guarantee. Revision rounds are included.

Step 3

Publishing

Free

A public page for your peer-reviewed preprint and its reviews. You keep the copyright, as with any preprint.

Where this goes

Review that is never wasted.

No rejections

Every submission enters an improvement loop with the experts who reviewed it. The review is a mentor, not a filter.

No journal silos

A review done once travels with the paper. Expert time is not thrown away every time a paper changes venue.

Auditable, later

We are working on a time-locked review record: confidential while the review runs, open to anyone’s audit once the paper is out.

Science deserves review as rigorous as the research.
