Best AI Tools for Teachers: Picks by Task, Compared

The best AI tools for teachers depend on the job. Lesson planning, grading feedback, leveled reading, and student-facing tutoring each have a different winner. This guide compares the leading tools by task, price, and privacy posture. Most classroom AI is free or cheap for individual teachers. Districts pay for oversight and integrations. Nothing here is firsthand testing. It is research-based assessment of published features and pricing.

The best AI tools for teachers at a glance

MagicSchool AI: best all-in-one classroom toolkit

MagicSchool AI is the most complete classroom toolkit in this group. It offers more than 80 teacher tools and more than 50 student tools. Instead of one chat box, you pick a purpose-built tool: lesson planner, rubric generator, quiz builder, IEP drafter, report-card comment writer, or parent-email composer. Each tool asks for grade level, subject, and standards up front, so the draft lands close on the first try. Raina, the built-in chatbot, answers open questions and suggests which tool fits a job. The free plan costs $0 and includes all tools with usage limits. Plus costs $12.99 a month, or $8.33 a month billed annually, and adds unlimited generations, unlimited output history, and the full student toolset. Enterprise is custom-priced for districts and adds single sign-on, LMS integrations, and admin dashboards. MagicSchool lists FERPA, COPPA, SOC 2, and GDPR compliance and says it does not use personal information to train models. It fits teachers who want one tool for the whole planning and paperwork load.

Khanmigo: best free teacher tools

Khanmigo is Khan Academy's AI tutor and teaching assistant, built on OpenAI models through Microsoft's Azure OpenAI Service. For teachers it is free in nearly every country. The teacher tools generate standards-aligned lesson plans, rubrics, quiz questions, and exit tickets. They sit on top of Khan Academy's existing content library, so the material is tied to lessons that already exist. Learner and family access costs $4 a month or $44 a year, and is currently limited to the United States. District pricing is custom. One limit matters: an individual teacher cannot grant Khanmigo access to students. Classroom student access requires a school or district implementation. The exception is Khanmigo Writing Coach, which Khan Academy made free for United States teachers to use with students. Khanmigo fits teachers who already use Khan Academy and want planning help at no cost.

Brisk Teaching: best AI inside Google Docs

Brisk Teaching is a Chrome and Edge extension that works inside the tools teachers already use. It overlays AI actions on Google Docs, Slides, PDFs, YouTube, and Canvas. Highlight text and Brisk suggests quiz questions, feedback, or summaries right there. No tab-switching, no copy-paste. Its feedback tools write comments in the teacher's voice and standard, using Glow and Grow or rubric criteria. Inspect Writing replays a document's edit history and flags writing that looks off. Brisk Boost is the student-facing side, giving students a monitored AI workspace. The free plan includes 20 or more tools with daily usage caps, plus a 14-day premium trial on sign-up. Educator Pro costs $99.99 a year and adds unlimited use and extra feedback styles. School and district plans are custom-priced. Brisk states FERPA, COPPA, GDPR, and SOC 2 compliance and holds a 93% Common Sense Privacy rating. It fits teachers who live in Google Workspace and want AI where the work already happens. It does not work in Safari or on mobile.

Diffit: best for leveled reading

Diffit does one job well. It turns a topic, text, PDF, URL, or video into reading material at the level your students need. Paste content, set the challenge level, MTSS tier, language, and scaffolds, and Diffit produces a leveled passage with comprehension questions, vocabulary, and summaries. It also generates activities, station rotations, and sub plans. Students never log in. Diffit says it collects no student data. The free Basic plan covers the core workflow with no generation cap, but only content made in the last 90 days stays accessible. Premium costs $14.99 a month or $149.99 a year and adds export to Google Docs, Slides, and Microsoft 365, standards alignment, and full resource history. School licenses are flat-rate annual quotes by enrollment. Diffit fits ELA, English-learner, and intervention teachers whose main prep job is adapting texts. It does not fit teachers who want a full lesson-planning system.

SchoolAI: best for monitored student AI spaces

SchoolAI flips the model. Instead of AI that helps the teacher plan, it gives students monitored spaces to chat with AI while the teacher watches. Teachers open a space, set the guardrails, and see usage and output. The teacher tier is free, which makes piloting easy. Paid Pro and Scale tiers add LMS integrations and deeper controls but require a demo call, so individual teachers cannot see the price. SchoolAI lists FERPA, COPPA, and SOC 2 compliance. It fits teachers who want students to practice with AI directly, under supervision, rather than only using AI for their own prep.

How to choose the best AI tools for teachers

Start from the task, then check privacy before price. Most of these tools are free or cheap for one teacher. The real cost is a bad data decision.

1. Name the task. Planning and paperwork point to MagicSchool. Feedback inside Docs points to Brisk. Leveled reading points to Diffit. Tutoring on Khan content points to Khanmigo. Student AI practice points to SchoolAI.
2. Check the free tier first. MagicSchool, Khanmigo, Brisk, and Diffit all have genuinely usable free plans. Try the free tier for two weeks before paying.
3. Read the privacy page. Confirm FERPA and COPPA alignment, ask whether student data trains models, and check whether your district needs a signed data-processing agreement.
4. Check where it lives. Brisk needs Chrome or Edge and Google tools. MagicSchool and Diffit are web apps. Khanmigo needs a Khan Academy account.
5. Review everything before it reaches students. AI output is a draft. A teacher checks it, edits it, and owns it.

Bottom line

MagicSchool AI is the strongest all-in-one pick for teachers who want one toolkit for planning, assessment, and communication. Khanmigo is the strongest free pick for teachers already on Khan Academy. Brisk Teaching is the strongest pick for teachers who live in Google Docs. Diffit is the strongest pick for leveled reading. SchoolAI is the strongest pick for supervised student AI use. Start free, check the privacy terms, and pick by the task you repeat every week.
