## Penelope

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.

- **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.

**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

**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

## Writefull

Writefull is a writing and proofreading tool designed for academics. Instead of relying on general-purpose language models, it uses models trained on millions of journal articles, so its feedback is tuned to the conventions, phrasing, and style of research writing. That calibration is why it tends to catch problems that generic proofreaders overlook, from awkward collocations to non-native phrasing that reads oddly in a paper.

The product lives where researchers already write. Writefull for Word delivers automatic language feedback inside Microsoft Word and can paraphrase, change style, explain, or summarize text. Writefull for Overleaf works within your LaTeX code and adds TeXGPT, which writes LaTeX for tables, formulas, and equations on demand. For pre-submission checks, Writefull Revise lets you upload a document, see its overall language quality, and fix errors with Track Changes. A set of AI widgets rounds things out: the Academizer turns informal sentences academic, the Paraphraser rewrites at three levels, and dedicated generators draft titles and abstracts based on your text or paper.

Writefull is used by students and researchers at more than 1,500 institutions and by major publishers and copyeditors, and it offers group and departmental licensing as well as premium access through institutional subscriptions. On privacy, the company states that texts and searches are processed over an encrypted connection and are never stored or used for training. It is available as a freemium product with paid and enterprise tiers.

**Pricing & Plans:** Writefull is sold as a freemium product: core features can be tried for free, while the full writing and proofreading toolkit requires a paid subscription. Institutional, group, and departmental licenses are available, along with premium access for universities and publishers and an enterprise offer. Exact pricing is provided on the vendor's site and via quote and may change.

- **Writefull for Word:** Get in-context language feedback automatically inside Microsoft Word, with options to paraphrase, change style, explain, or summarize text.
- **Writefull for Overleaf and TeXGPT:** Receive language feedback directly within your LaTeX code in Overleaf, generate LaTeX automatically, and use TeXGPT for tables, formulas, and equations.
- **Writefull Revise:** Upload a document before submission to see its overall language quality and apply corrections with Track Changes.
- **AI writing widgets:** Academizer turns informal sentences academic, the Paraphraser offers rewrites at three levels, and generators draft titles and abstracts from your text.
- **Citation support:** Writefull Cite helps you add and manage citations, rounding out a toolkit built for the academic publishing workflow.

**Strengths:** Language feedback specifically calibrated for academic writing; Integrates directly into Word and Overleaf workflows; Widgets for paraphrasing, academicizing, and generating titles and abstracts; TeXGPT automates LaTeX authoring for tables and equations

**Limitations:** Focused on academic English, so less suited to casual or marketing writing; Full premium features require a paid subscription or institutional access; Works best inside Word or Overleaf, so plain-text workflows are less covered; Non-English source support is limited compared to general proofreaders
