Do you really trust Outlook’s Spell Checker?

Think Microsoft Outlook catches every mistake? We put it to the test.

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

Outlook 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.

MerciApp combines analytical algorithms with real linguistic expertise

Outlook flags mistakes based on the errors its users make most often. MerciApp, on the other hand, uses true language-processing engines that understand the syntax of your sentences.

Outlook’s spell checker doesn’t rely on a corpus corrected by professional linguists, it works with texts found online, which often contain plenty of mistakes.

To complement its powerful analysis engines, MerciApp maintains a massive corpus of corrected texts (over 250 million words) to continuously improve its algorithms in real time. Every day, MerciApp gets better at understanding complex sentences while minimizing false positives.
