Your words, not ours

J’aime la facilité avec laquelle les corrections se font et le temps que ça fait gagner à l’équipe. J’aime recevoir un e-mail sans faute d’orthographe.

Très facile à utiliser, j’aime aussi les explications de MerciApp qui me font progresser au quotidien.

Quand on échange avec des décideurs de haut niveau, une faute dans un e-mail de prospection peut décrédibiliser la société. Chaque e-mail important était relu par une autre personne. Au final, je me suis rendu compte que Gmail laissait passer beaucoup de fautes de grammaire. Merci MerciApp !
We launched MerciApp in 2020 with Diagonal, a French leader in proofreading.
Our goal was simple: help 300 million French speakers worldwide communicate better.
