*Correct my mistakes: serves to assist in the proper writing sentences online. We launched this project to help people in everyday typing situations, fix punctuation errors, etc.. Help consists of writing capital letters where needed, creating a space between letters, or erasing an unnecessary space. The program is based primarily on English grammar and works as a simple "grammar check and correct". The program does not have the option to correct spelling errors and does not have the option to reduce capital letters, the reason being the capital letters in the people names, cities, etc... If you want to edit inconsistent sentence with a capital letters, first use the "lower case" option (convert whole text), then "Correct my mistakes". Please understand, there are many rules to include and apply. This is a beta version, we work on it every day. Mistakes are possible and expected at this stage. If you notice a mistake, please contact us and give us an example it will help us to improve the program. When to use: if you want to check the quality of your writing sentence. If you want to correct the incorrectly written sentences. If you are just a beginner and you do not know how to write correctly. If you have copied interesting text and want to correct it.
