Axios: “A new tool called Writable, which uses ChatGPT to help grade student writing assignments, is being offered widely to teachers in grades 3-12. Why it matters: Teachers have quietly used ChatGPT to grade papers since it first came out — but now schools are sanctioning and encouraging its use. Driving the news: Writable, which is billed as a time-saving tool for teachers, was purchased last summer by education giant Houghton Mifflin Harcourt, whose materials are used in 90% of K-12 schools.

• Teachers use it to run students’ essays through ChatGPT, then evaluate the AI-generated feedback and return it to the students.
• “We have a lot of teachers who are using the program and are very excited about it,” Jack Lynch, CEO of Houghton Mifflin Harcourt, tells Axios.

How it works: A teacher gives the class a writing assignment — say, “What I did over my summer vacation” — and the students send in their work electronically.

• The teacher submits the essays to Writable, which in turn runs them through ChatGPT.
• ChatGPT offers comments and observations to the teacher, who is supposed to review and tweak them before sending the feedback to the students.
• Writable “tokenizes” students’ information so that no personally identifying details are submitted to the AI program…”
