What is KERNIT?
KERNIT is a browser-based academic paper formatter. It accepts DOCX, Markdown, or plain text and applies the typographic rules of 9 major journal styles: IEEE, APA 7th Edition, Nature, Elsevier, ACS, Springer, PLOS ONE, The Lancet, and JAMA. Output formats are DOCX (editable Word file), LaTeX (.tex source), and HTML. KERNIT does not modify, paraphrase, or otherwise process your writing — it only changes layout and formatting. Everything runs locally in your browser.
KERNIT also includes a Cross-Reference Hyperlinker: upload an existing Word DOCX and it automatically hyperlinks citations, figure/table/equation references, section references, and DOIs throughout the document.

Purpose: Paperpal is an AI language editor that checks and improves your academic writing — grammar, vocabulary, and journal-specific phrasing. KERNIT is a typographic formatter that applies journal layout rules without editing your writing. They solve different problems: use Paperpal to improve your prose, use KERNIT to apply journal formatting.
-
Will KERNIT change my academic writing?
No. KERNIT is a layout tool, not a writing tool. It changes typography (font, spacing, margins, heading levels, column layout) without modifying your words. Every sentence you write appears in the output exactly as written. This is critical for researchers who need to attest that manuscript content is entirely their own work.
-
Is my manuscript private when using KERNIT instead of Paperpal?
Yes. KERNIT processes all formatting and hyperlinking in your browser. Your manuscript text is never sent to any server. Paperpal sends your text to their AI infrastructure for analysis. For researchers with sensitive unpublished data, KERNIT's browser-only processing is the more private option.
-
Does KERNIT check grammar like Paperpal?
No. KERNIT does not perform grammar checking, language editing, or writing suggestions. It is purely a formatter. If you need academic language checking, Paperpal is a dedicated tool for that purpose. KERNIT is the right tool after your writing is done and you need to apply journal formatting before submission.
