Google introduced an intelligent spell checking in Google Docs and Presentations. Instead of relying on a fixed dictionary, now it makes contextual text suggestions from the web – just like Google search engine spell checker do. This new update has following advantages over traditional spell checkers.
“Suggestions are contextual. For example, the spell checker is now smart enough to know what you mean if you type “Icland is an icland.”
“Contextual suggestions are made even if the misspelled word is in the dictionary. If you write “Let’s meat tomorrow morning for coffee” you’ll see a suggestion to change “meat” to “meet.”
“Suggestions are constantly evolving. As Google crawls the web, we see new words, and if those new words become popular enough, they’ll automatically be included in our spell checker—even pop culture terms, like Skrillex”.
This new spell checker is available for English documents only, however Google will bring it to more languages soon. (Via – Google Docs blog)
