KERNIT vs Citavi for
Cross-Reference Linking
Citavi's Word Add-In can link citations to your bibliography — but it doesn't support footnote citations, slows down Word so much that Citavi officially recommends enabling it “only shortly before final submission,” and doesn't support footnote-style citations. KERNIT works instantly in any browser, with every citation style, and zero Word slowdown.
TL;DR — Quick answer
KERNIT is a free, browser-based cross-reference hyperlinker that works on any platform with any DOCX. Citavi is a ~$519/yr reference manager whose Word Add-In can link citations but is Windows-only, slows Word significantly, and skips footnote citations. If you just need citation linking, KERNIT does it for free without the overhead.
What is Citavi?
Citavi is a reference management and knowledge organization tool developed by Lumivero (formerly Swiss Academic Software). It combines citation management, task planning, and PDF annotation into a desktop application for Windows. Pricing starts at ~$519/year for a subscription or ~$291 for a perpetual license.
Among its features, Citavi's Word Add-In can create hyperlinks between in-text citations and bibliography entries. However, this linking feature has significant limitations:
No Linux or Chromebook support
Citavi's Word Add-In is available for Windows and Mac. Linux and Chromebook users are excluded entirely. The add-in requires a desktop installation of Microsoft Word — it does not work on Word for the web or any non-Windows/Mac platform.
Slows down Word significantly
Citavi's own documentation acknowledges that enabling citation linking causes noticeable slowdown in Word. Their recommended workflow is to keep linking disabled during writing and editing, and enable it “only shortly before final submission.” For large manuscripts with hundreds of references, the performance impact can be severe.
No footnote citation support
Citavi's Word Add-In does not support creating hyperlinks for footnote-style citations — a format commonly used in humanities, law, and social science journals. If your journal uses footnote citations, Citavi's linking feature simply doesn't work.
Requires active Citavi field codes
Citation linking in Citavi only works with documents that contain active Citavi field codes. If you remove the field codes, paste citations manually, or receive a DOCX from a co-author who doesn't use Citavi, the linking feature cannot process the document.
What is KERNIT?
KERNIT's Cross-Reference Hyperlinker is a browser-based tool that adds clickable hyperlinks to any Word DOCX. Upload your manuscript, and KERNIT automatically detects and links citations, figure references, table references, equation references, section references, and DOIs — all in your browser, in seconds.
KERNIT works with any DOCX file regardless of how citations were created — typed manually, exported from Citavi, Zotero, EndNote, Mendeley, or any other reference manager. No field codes, no Add-Ins, no desktop install. It supports all citation styles including numbered, author-date, superscript, and footnote.
Because KERNIT processes your document outside of Word, there is zero impact on your editing workflow. No slowdown, no need to toggle features on and off. Your file is processed entirely in your browser and never leaves your device.

Frequently asked questions
-
Does Citavi slow down Word?
Yes. Citavi's own documentation recommends enabling the citation linking feature “only shortly before final submission” because it significantly slows down Word. For large manuscripts with hundreds of references, the performance impact can make editing impractical. KERNIT processes your DOCX outside of Word entirely, so there is zero impact on your editing workflow.
-
Can Citavi link footnote-style citations?
No. Citavi's Word Add-In does not support creating hyperlinks for footnote-style citations. This affects researchers in humanities, law, history, and many social science disciplines where footnote citations are the standard format. KERNIT supports all citation styles including footnotes, numbered
[1], author-date(Smith, 2024), and superscript. -
Does Citavi work on Mac?
Citavi's desktop application and Word Add-In are Windows only. Citavi Web exists as a browser-based version for reference management, but it does not include the citation linking feature — that requires the desktop Word Add-In. KERNIT works in any modern browser on any operating system: Mac, Windows, Linux, and Chromebook.
-
Is Citavi's $519/year price just for citation linking?
No. Citavi is a full reference management and knowledge organization tool — citation linking is just one feature within the Word Add-In. If you primarily need cross-reference hyperlinks in your manuscripts, KERNIT provides that specific functionality for free without requiring a reference manager subscription or any desktop software.
-
Can I use KERNIT with Citavi-formatted documents?
Yes. KERNIT works with any DOCX file regardless of how citations were created — whether typed manually, exported from Citavi, or managed by any other reference manager. No special field codes required. You can even use KERNIT to add figure, table, and equation reference links that Citavi's Add-In does not support.
