LexyronYour terminology, explained inside every Word document.
Lexyron finds the terms and abbreviations from your dictionaries in the text, adds their definitions as footnotes in one click and builds the glossary at the end of the document.
Free, for Word on Windows, Mac and the web. Coming soon to Microsoft Marketplace.

How it works
Lexyron opens as a pane next to your document. Your text never leaves your computer.
Import your dictionary
Excel, CSV, JSON or ZIP, password-protected ZIP too. Or paste a table straight from Excel.
Check the document
Terms and abbreviations from your dictionaries are underlined, including plurals and Lithuanian case endings.
Add the footnote
Click a term to see its definition from every dictionary that contains it, then insert it as a footnote.
Insert the glossary
An alphabetical list or table of the terms you used, placed at the end and updated in place.
For documents where terms matter
Anywhere a reader needs the exact definition from the source, not a paraphrase.

Your dictionaries stay yours
Lexyron does not ship with dictionaries. You bring your own: a company glossary, the definitions section of a regulation, a standard you are licensed to use, or a list you build as you write.
Dictionaries are stored only on your computer. Use as many as you like at the same time and set which one has priority when a term appears in several.
Free dictionaries prepared by the Lexyron team will be published on Zenodo with a citable DOI.

Questions
Does Lexyron send my documents anywhere?
No. Lexyron reads the text of your document inside Word to find terms. Your documents and dictionaries are never uploaded.
Which languages are supported?
Dictionaries can be in any language. For English and Lithuanian, Lexyron also recognises inflected forms automatically. For other languages, list the forms you need in the Forms column.
Which versions of Word work?
Word for Microsoft 365, Word 2021 and 2024 on Windows and Mac, and Word on the web. Spell-checker-style underlining needs Microsoft 365; other versions highlight the terms instead.
Can I use dictionaries from standards or publishers?
Yes, if you have the right to use their content. Lexyron does not check or store what you import.
What happens to my footnotes if I stop using Lexyron?
Nothing. Footnotes and glossaries are ordinary Word content and stay in your documents.
