Copyleaks
The multilingual specialist, covering 30+ languages.
Copyleaks differentiates on language reach.

That makes it the credible pick for international institutions and businesses shipping content in Spanish, Portuguese, French, German, Arabic, and beyond. Pricing starts at $7.99 a month for the Essential tier, the most affordable among the serious detectors, with enterprise tiers that scale for institutional deployments. It is widely used in higher education outside the English-speaking world.
