an AI text leveler that can translate a given article, excerpt, or even YouTube video to any reading level from second to 11th grade. Using the same large language model technology that powers ChatGPT, Diffit parses complex texts (or captions from a video) and produces an accessible summary, along with a relevant vocabulary list with definitions; it can also generate assessment questions. 

Educator Michele Haiken describes it as an ideal tool to try with an article that you “want to use for your lesson, but is too hard for some (or all) of your readers.” Recently, Kristen Starnes, who teaches high school social studies near Milwaukee, used the tool to adapt The Federalist Papers—a challenging collection of 18th-century essays—for her 11th-grade students. Though she might ask students to wrestle with the original text at first, she also provides a modern translation at a reading level appropriate for each student. “I have kids who have IEPs who are reading at different levels, and it’s really nice to have essentially the same reading, just leveled appropriately,” she says.

Teachers create assignments and invite students to complete them on the site. Teachers can write their own assignments and set the format (essay or short answer), along with the rubric, the sources or texts, the questions, and submission guidelines. A searchable library, populated with lessons from other teachers, is available as well. 

Teachers can also use Class Companion to create assignments using a prompt. For instance, the prompt “President Lincoln’s stance on slavery” will produce paragraph-long essay questions in a matter of seconds along these lines:
