## Overview

Penelope.ai is a manuscript compliance service for scientific publishing. Its job is narrow and useful: before a paper reaches a human reviewer, confirm that it actually satisfies the journal's own author guidelines. Journals define dozens of rules — does an ethics statement section exist and is it in the right place, is the review board named, is informed consent addressed, are conflict of interest and data sharing declarations present, does the abstract follow the required structure, do the figure and table mentions match their legends, are citations and references consistent, does the article exceed the word limit, has the author left track changes in the file.

Penelope runs those rules automatically and reports back with links into the marked-up manuscript, so nothing is a black box. Every check's pass and fail criteria are documented, which matters for editorial transparency and for authors who may query a result. Journals configure which of the 30-plus checks apply, which failures are critical, and precisely how feedback should be phrased to editors and authors. Results can appear at a summary level inside the manuscript handling software or as a full annotated interactive report.

The commercial model is per-journal rather than per-writer. Pricing scales with annual submission volume and includes the complete suite of checks and metadata extraction, with the option instead to offer author-paid checks at no cost to the publisher. Penelope is based in London, UK, and is available to journals using Manuscript Manager, with waiting lists for Editorial Manager and ScholarOne.

## Pricing & Plans

Priced per journal by annual submission volume (excl. VAT), and every tier includes the full check suite plus metadata extraction. Indicative rates: around £1.50 per submission below 500 annual submissions, £1.20 for 501–1,000, £1.00 for 1,001–2,500, and £0.80 for 2,501–5,000 and above; annual packages are quoted as roughly £750, £1,350 and £2,850 in the lower bands, with higher volumes quoted directly. Publishers can alternatively let authors pay for checks themselves at no cost to the journal.

## Key Features & Capabilities

- **30+ configurable manuscript checks:** More than 30 checks spanning ethics approval and informed consent, conflict of interest, data sharing, funding, author contributions, abstract structure, required headings, figures and tables, referencing style, word counts and file cleanliness.
- **No black box — linked evidence:** Every result is tied to the relevant marked-up section of the manuscript, so editors and authors can see exactly which sentence or heading produced the pass or fail — the criteria are published in the developer documentation.
- **Journal-by-journal configuration:** Journals decide which checks to run, which are critical, and how the feedback reads, defined on a journal-by-journal basis to match that publication's author guidelines.
- **In-platform and full reports:** Top-level results surface inside the manuscript handling software, while a full interactive report gives the deeper annotated view for editors and authors.
- **Metadata extraction:** Title, page numbers, double line spacing, registered trademarks and other metadata are pulled out automatically as part of every run.

## Primary Use Cases

- **Cut first-pass triage time (Managing editor):** Send submitted papers through Penelope first so incomplete or non-compliant manuscripts are returned to authors before a reviewer's time is spent.
- **Pre-flight your submission (Author):** Run the checks yourself before hitting submit and fix missing declarations, abstract structure issues or reference mismatches up front.
- **Enforce guidelines consistently (Journal operations lead):** Encode your own author guidelines as configurable checks and let automated feedback enforce them consistently across every article type.
- **Give authors actionable feedback (Editorial office staff):** Use the linked, section-level results to quickly explain to an author exactly why a manuscript was sent back and what to change.

## Strengths

- Directly targets the tedious first-pass triage that eats editorial time
- Transparent criteria and linked evidence instead of an opaque score
- Per-journal configuration means feedback matches each publication's actual guidelines
- Metadata extraction comes bundled rather than as a paid add-on
- Author-facing feedback reduces the volume of incomplete submissions

## Limitations

- No self-serve author checkout — authors get results only when their target journal has switched checks on
- Native integration is limited to Manuscript Manager today; Editorial Manager and ScholarOne users sit on a waiting list
- Checks are structural and policy-based, so it will not catch scientific or statistical errors in the content
