AI Tools for Teachers: A Practical Stack That Saves Real Time
AI tools for teachers work best as a small stack, not a pile of apps. Pick one tool for planning, one for feedback, and one for adapting reading material. Learn those three well. Then add more only when a real gap appears. This guide compares the main options on their official pricing pages and free plans, so you can build a stack that fits your budget and your school rules. Everything here is research-based. We did not test these tools in a live classroom.
What AI tools for teachers should actually do
A good teacher tool saves time on repeatable work. Lesson planning, quiz writing, rubric drafting, and parent emails are repeatable. Grading feedback is repeatable too, once you set the rubric. A tool earns its place when it drafts those jobs in minutes and leaves the judgment to you.
Check three things before you adopt any tool. First, does your school allow it? Many districts block tools that are not approved. Second, does it protect student data? Look for a clear privacy policy and a statement that student work is not used to train models. Third, does the free plan cover your real workload? Some free plans cap generations. Others limit how long your work stays saved.
Keep one rule for every output. AI drafts, you decide. Read every lesson plan, rubric, and feedback comment before it reaches a student. AI can invent facts, misread a rubric, or set the wrong reading level. Your review is the quality control.
The planning core: MagicSchool and Khanmigo
MagicSchool is the broadest single toolkit in this guide. Its pricing page lists more than 80 teacher tools. They cover lesson planning, worksheet generation, quiz generation, IEP drafting, and presentation creation. It also lists more than 50 student tools, plus a chatbot called Raina. The free plan costs $0 and is described as forever free for individual teachers. It includes the 80-plus teacher tools, Raina, quizzes, and class writing feedback, with standard generation limits.
MagicSchool Plus costs $12.99 a month when billed monthly, or $8.33 per user a month when billed annually. Plus adds unlimited generations, unlimited output history, unlimited output editing through Studio Mode, the 50-plus student tools, and student learning insights. Districts buy Enterprise at a custom price. That tier adds a custom data privacy agreement, single sign-on, SIS and LMS integrations with Clever, ClassLink, Canvas, and Schoology, and district dashboards.
Khanmigo takes a narrower path. It is Khan Academy's AI tutor and teaching assistant. Microsoft's education blog describes Khanmigo for Teachers as free in English across 49 countries, in partnership with Microsoft. It offers more than 25 educator tools for lesson ideas, rubrics, exit tickets, and summaries of student work. The tools sit inside Khan Academy's content library, so outputs can link back to Khan Academy lessons and practice.
The free teacher tier has one limit worth knowing. Individual teachers cannot switch Khanmigo on for their own students. Classroom student access runs through school or district agreements. If your students already use Khan Academy daily, Khanmigo fits your workflow. If they do not, MagicSchool's wider toolset may serve you better.
Feedback where you already work: Brisk Teaching
Brisk Teaching works as a Chrome and Edge browser extension. It sits inside Google Docs, Slides, PDFs, YouTube videos, and web articles. You open a student's essay in Docs, click the Brisk button, and the feedback lands as comments in that essay. There is no copy and paste step. That is the whole point.
Brisk offers a free plan for individual teachers. It includes core tools such as the quiz generator, lesson plan generator, rubric generator, and presentation maker. Its official extension page says Brisk complies with COPPA, FERPA, and SOC 2 standards, and that it never uses teacher or student data to train AI models. It also earned a 95 percent rating from the Common Sense Privacy Program, according to the same page.
Brisk also sells an individual Educator Pro upgrade and custom-priced Premium and Intelligence plans for schools and districts. The district plans add standards alignment, admin dashboards, professional development, and student-facing tools. Brisk works only in Chrome and Edge. There is no mobile version, so it suits teachers who grade on a laptop or Chromebook.
One text, many reading levels: Diffit
Diffit does one job well. You paste a text, upload a PDF, add a link or video, or type a topic. Diffit builds a leveled reading passage, comprehension questions, vocabulary lists, and summaries. You can set the grade level and the challenge level. It suits mixed-ability classes where one text must reach every student.
Diffit's Basic plan is free. It covers the core workflow: create, edit, download to PDF, print, and share. The catch is the window. Basic keeps access only to resources created in the last 90 days. Older resources sit outside the free plan, so export your work the same day you make it.
The individual Premium plan costs $14.99 a month or $149.99 a year. It adds export to Google Docs, Slides, and Microsoft Word, alignment to standards and MTSS tiers, full resource history, and graphic organizers. Schools buy a separate license priced by enrollment. Diffit states that there are no student logins and no student AI. Teachers make the materials, and students use what is printed or shared.

How to set up your stack in one week
Start small and test each tool on real work. A one-week rollout keeps the change manageable.
- Day 1: check your school policy. Ask your IT lead which AI tools are approved. Do not put student names or work into a tool your district has not cleared.
- Day 2: set up MagicSchool free. Generate one lesson plan and one quiz for a topic you teach next week. Edit the output. Note what you changed, so you learn the tool's weak spots fast.
- Day 3: try Khanmigo for Teachers. Build a rubric and an exit ticket for the same lesson. Compare the two tools side by side. Keep the one whose drafts need less fixing.
- Day 4: install Brisk. Grade one set of essays with its feedback tool. Check every comment before you send it. Time yourself, and compare it with your usual grading time.
- Day 5: test Diffit. Take one text your class will read next week. Generate it at two reading levels with vocabulary and questions. Print or download the PDFs the same day.
- Day 6: pick your stack. Keep the tools that saved real time. Drop the rest. Write down your weekly routine: which tool, which job, which day.
- Day 7: review privacy. Confirm that no student data went into an unapproved tool. Save your prompts and rubrics in one document, so next week starts faster.
What to watch out for
Free plans have limits that only show up with heavy use. MagicSchool's free plan has standard generation limits, and it does not include unlimited output history. Diffit's free plan drops access to work older than 90 days. Brisk's free plan covers the core tools, but the faster AI engine and extra feedback styles sit in paid tiers. Read the plan page before you build a routine around a free feature.
AI output needs a human check every time. A lesson plan can cite a standard your state does not use. A quiz can include a wrong answer. Feedback can sound encouraging while missing the real error in a student's work. Budget five minutes to review each output. That review time is still far less than writing from scratch.
Student privacy comes first. Never paste student names, grades, or identifiable work into a general chatbot. Use tools your school has approved. Check whether the tool uses inputs to train models. Brisk and MagicSchool both publish statements on this point. If a tool does not, ask before you use it with student work.
Bottom line
Start with MagicSchool free for planning and Khanmigo for Teachers for rubrics and exit tickets. Both cost nothing for teachers. Add Brisk if you grade in Google Docs and want feedback inside the document. Add Diffit if your class spans several reading levels. That four-tool stack covers planning, feedback, and differentiation for most teachers, and only MagicSchool Plus or Diffit Premium costs money. Pay for one only after the free plan has proved its worth in your classroom.
