Swiftkey is already one of the most accurate keyboards around when it comes to auto correct. Swiftkey has just released their first "Greenhouse" experimental project which promises to bring even better auto correct to your keyboard. The beta version of Clarity brings multiword auto correct to the swiftkey keyboard. This takes into account the context of what you type to intelligently auto correct the words you type as you type them.
Here is an example of how this could work. "I will do this on the future" would be corrected to "I will do this in the future". The correction would take place even though none of the words are actually misspelled. Auto corrects can be undone by tapping the backspace. You can find the Clarity beta at the link below.
