Best AI Tools for Teachers in 2025: Lesson Plans, Grading, and Learning

Best if: you are a K-12 teacher who wants everything in one place with education-specific templates — and you don't want to figure out how to prompt a general AI tool for each use case.

Input your subject, grade level, duration, and standard into the Lesson Plan Generator and get a complete lesson plan in about 30 seconds — with learning objective, hook, direct instruction, guided practice, independent practice, and exit ticket. The Rubric Maker generates rubrics with specific observable descriptors. The IEP Goal Generator helps special education teachers create measurable annual goals. The Parent Letter Writer drafts professional communications in seconds.

Best if: you want to assign AI tutoring to students in a pedagogically sound way — where the AI teaches rather than gives answers, and you can monitor what students are struggling with.

Khanmigo is designed for student-facing use, which means it has COPPA compliance built in — unlike using ChatGPT with students. The teacher dashboard shows which topics your students are working on and where they are stuck. For SAT prep and AP exam support, Khanmigo walks students through problem types with guided practice, not just solutions.

Best if: you want maximum flexibility for customized lesson plans, differentiated assignments, quizzes, and rubrics — and you are comfortable writing specific prompts.

Best if: you are an ELA or humanities teacher who needs substantive, high-quality written feedback on student essays, or who creates detailed unit plans and curriculum documents.

Claude's 200k context window means you can paste an entire student essay and ask for paragraph-by-paragraph feedback. For curriculum design, Claude excels at building comprehensive unit plans that connect multiple lessons to a central theme and essential questions — not just a list of activities, but a coherent instructional arc. The writing quality of Claude's rubric descriptors is noticeably more specific than most AI tools.

Best if: you grade student work in Google Docs or Google Classroom and want AI feedback suggestions without leaving the document.

Open a student essay in Google Docs, click the Brisk extension, and choose from: suggest a grade, generate feedback comments, check for AI-generated content, or check the reading level. Brisk reads the document directly — no copying and pasting. The Lexile/grade level feature tells you instantly whether a text is appropriate for your class reading level, which is useful for evaluating supplementary materials.

Best if: you teach ELL students, have mixed reading levels in your class, or spend significant time adapting texts for different learners.

Input a topic, paste text, or provide a URL and Diffit generates a reading passage at five Lexile levels — from second grade to adult — all covering the same content. It also generates comprehension questions, vocabulary lists, and graphic organizers for each level. What would take a teacher hours of text adaptation takes Diffit under a minute.

Best if: you want engaging, interactive lesson presentations without spending hours in PowerPoint — and you want students to participate live during the lesson.

Input your topic and grade level, and Curipod generates a complete interactive presentation — not just slides with text, but a lesson that includes polls for checking prior knowledge, reflection prompts, word clouds where all students answer simultaneously, and exit ticket quizzes. Students join with a code (from any device) and their responses appear on your projector screen in real time.
