Discover the Virtual Writing Tutor, a free online grammar checker and essay scorer with ESL-focused feedback, vocabulary analysis, and IELTS practice

The Virtual Writing Tutor is a free online essay checker and grammar assistant developed by ConverSolo Inc. You can paste paragraphs containing mistakes, click “Improve writing,” and the tool will correct errors and rephrase sentences in standard English. It can also score essays, assign an overall grade, offer improvement tips, check your CEFR level, analyze English proficiency, and help with vocabulary, spelling, grammar, and punctuation.

Nicholas Walker, an ESL teacher at Ahuntsic College in Montreal, Quebec, Canada, launched the website on April 5, 2012. His goal was to improve ESL writing instruction by giving students feedback that was more frequent, higher quality, and delivered sooner. The site is connected to Bokomaru Publications, which creates free and low-cost tools for ESL learners.
