Diffit is an AI assistant for teachers that produces instructional materials matched to each student's level. You enter a topic or paste existing content, optionally specify an MTSS tier, challenge level, language, scaffolds and standards, and receive differentiated activities, station rotations, sub plans, intervention materials, slides and more. Built-in editing tools let you adjust the result without losing rigor, and layouts are ready to print.
Classroom teachers, instructional coaches and specialists working with English learners, special education and intervention groups are the core users. Schools and districts adopt it to give staff a consistent, curriculum-aligned way to supplement core materials, and there are no student logins or student-facing AI, which simplifies privacy reviews. The company states that it collects zero student data and supports DPA compliance and accessibility requirements.
Teachers use it to rewrite a grade-level reading passage for several reading levels, build a set of tasks for a rotation, prepare a substitute plan on short notice, or create supplemental practice for a book, standard or skill. Finished resources can be printed or sent to Google Docs, Slides, Forms and Classroom, or to Microsoft 365, and exports stay editable so pieces can be mixed. Resources can be organized and shared with colleagues. In a survey of 2,517 teachers, 96 percent said it saves them time and 86 percent said it makes them a better teacher. Because every resource stays editable, a teacher can generate a base version once and then adapt it for different classes, reading levels or languages without starting over, which keeps preparation time low across a full week of lessons.
