When you have a SpanishDict Premium subscription and use SpanishDict.com (the website, not the app), you can use our Writing Coach to proofread the sentences you write in Spanish (or English) to ensure that the grammar and spelling are correct.
To find this feature on a computer, open SpanishDict.com, sign into your Premium account, click on the three dots at the top of the page, and then select "Writing Coach".
You can then type or paste text into the box (in Spanish or English) and click the "Proofread" button on the right-hand side. You also have options to listen to the text you wrote, easily copy the text, or translate the text.
After clicking on that button, the sections of your text that have grammar errors will be highlighted in green, and the spelling errors will be marked in red.
When you hover your mouse over a highlighted section, a box will pop up that explains what the error is and how to correct it. Once you make your corrections, click the "Proofread" button again to check your corrections and scan for any remaining problems.
