Our verdict: Grammarly

Recommended for French-speaking freelancers and SMEs who regularly write in English (international clients, export, applications) and want reliable orthographic and stylistic safety net. Not suitable if your need is French writing: Grammarly doesn't correct that language; use a dedicated tool like LanguageTool instead.

Our verdict: LanguageTool

Recommended as a priority for French-speaking freelancers and SMEs who want reliable French correction without depending on an English-first tool: good value, API available and open-source for technical teams. Not suitable if you're looking for complete content generation: LanguageTool corrects and rewrites but doesn't draft articles or long texts from scratch.
