I built a little app last week that grades your writing like an English teacher, red pen and all. :) Drop in an essay, resume, cover letter, or email, and you get your own page back covered in red ink: circled mistakes, corrections above the line, notes squeezed into the margins, and a letter grade at the top. https://www.gradethis.app/ Its free, no sign up needed, and nothing is stored anywhere. Would love to hear feedback on what you think..   submitted by   /u/Slight-Manner-4460 [link]   [comments]
