Overview
MerciApp starts from a simple observation: employees spend hours every day writing, proofreading and correcting. The tool installs on Chrome in one click and works directly inside text fields across your tools, with no copy-pasting.
Features:
- Correction of spelling, grammar, conjugation and typography, with particular strength in French.
- AI rewriting: make a message clearer, shorter, more polite or more direct.
- Tone and style aligned with your company, for consistent writing across teams.
- Dashboard to measure time saved per employee.
MerciApp claims more than 350,000 professional users, especially support, customer success and sales teams.
Pros

- Free plan and a 30-day trial.
- French company, a plus for data confidentiality.
Cons
- Advanced AI rewriting is on the paid plan.
- Works mainly through the browser: less handy in desktop apps.
- As with any checker, keep a critical eye on suggestions.
Studio Elias’s recommendation
A brand is also a way of writing. MerciApp helps a team keep its everyday writing clean and consistent, especially in roles that write to customers all day. To go further, formalise your brand’s tone of voice in your brand platform (words to use, words to avoid, level of familiarity): the tool fixes the form, your platform guides the substance.
