MerciApp corrects spelling and grammar mistakes that Gmail doesn’t even notice

Gmail only catches basic spelling & grammar errors.

MerciApp corrects spelling mistakes on over 90,000 common nouns and spots sophisticated grammar errors using advanced syntactic, semantic, and contextual analysis, even when the problematic words are far apart in a sentence.

Gmail relies on statistics. MerciApp uses analytical algorithms and real linguistic expertise.

Gmail flags the mistakes it sees most often among its users, but MerciApp goes much further. Our engine is built on true language-processing technology that understands the syntax and structure of the sentences you write.

Unlike Gmail, whose spellchecker is trained on texts found online (many of which contain errors), MerciApp is powered by a curated corpus reviewed by professional linguists.

On top of its advanced analysis engines, MerciApp maintains a massive database of corrected texts — more than 250 million words — to continuously improve its detection models. Every day, MerciApp learns to understand more complex sentence structures, reducing false positives to an absolute minimum.

  • MerciApp saves our client-facing teams (Sales, Support, CSM) time on email proofreading so we can focus on delivering great service rather than hunting for mistakes. With the app, I feel confident sending important emails and skip multiple rounds of proofreading and unnecessary stress before hitting “Send.” Its educational features help us quickly learn from our most common errors, which is essential for our team.
