With release v5.7.0 we introduced an enhanced AI-based proofreading engine for English. It was built using modern approaches in Natural Language Processing (NLP). Unlike the classical rules or dictionary-based engines, it's based on the huge pretrained model. Its accuracy at least 3 times better.

However, at the same time, there are some cons that should be taken into consideration:

• It is available for general English. It doesn't distinguish dialects. Thus, offered as a separate language.
• Suggestions can be unpredictable and there is no option to ignore a rule.
• AI technology consumes more resources to provide the results. Check the updated WebSpellChecker Server v5.7.0 hardware requirements.
