The free plan targets occasional writers with 600 analyzed words and three Transform rewrites per day; Assist starts at €12 per user per month, while Enterprise requires 20 seats and has no listed price.

Choosing instead of MerciApp
Readers may consider alternatives for broader language coverage, German-only checking, tone detection, AI content detection, API access or different platform needs. Compare each product’s writing tools, language range, extensions and applications before switching. MerciApp has no mobile app, despite iOS and Android appearing in its platform list, and its Windows app has partial compatibility with some applications. Also weigh what you would leave behind, including MerciApp’s assistants, snippets, integrations and its stated European hosting and privacy practices.
