Grammalecte vs Linguix

Grammalecte is free, GPL 3 open-source software for checking French grammar and typography. It detects punctuation, spacing, typography, repeated words, hyphenation, capitalization, agreement, conjugation, confusions, and pleonasms. Users can enable or disable error categories and choose Classic, 1990 Reform, or All Variants spelling dictionaries, with Classic selected by default. Suggestions use several mechanisms, and an OCR option can detect errors in text produced by optical character recognition. A formatter addresses recurring errors and restructures text; its conjugator covers about 8,000 verbs. Grammalecte is available as a desktop app and browser extension on Linux, macOS, and Windows. Listed integrations include LibreOffice or OpenOffice, Firefox, Thunderbird, a command-line interface, server, and Python package. The FAQ says writing is analyzed locally, with no data collected or text transmitted. The maker says the checker does not perform semantic analysis, can miss mistakes, and may produce false positives. There is currently no version compatible with Chrome’s new extension API.
