The education AI space is getting crowded fast. A year ago, MagicSchool was basically the only option. Now there’s Diffit, SchoolAI, Brisk, and a dozen others: each claiming to be “the AI tool teachers actually need.”

I’ve spent significant time with the three biggest players: MagicSchool, Diffit, and SchoolAI. Each takes a genuinely different approach, and the right choice depends on what problem you’re trying to solve. Here’s how they compare on the things that actually matter.

Quick Comparison

MagicSchool

What it does

MagicSchool offers 60+ AI tools specifically for teachers: lesson plan generator, rubric creator, IEP goal writer, email drafter, assessment builder, and more. It’s the Swiss Army knife approach.

Pros

• Breadth of tools: if you need it, MagicSchool probably has it
• Teacher-specific prompts: no prompt engineering needed
• Raina (AI assistant): chat-based AI that understands education context
• Free tier is generous: enough for casual use

Cons

• Jack of all trades: individual tools aren’t as deep as specialized alternatives
• Output quality varies: some tools produce excellent results, others are generic
• Can be overwhelming: 60+ tools means a learning curve to find what you need

Best for

Teachers who want one platform for everything: planning, admin, communication, assessment.

Diffit

What it does

Diffit focuses on one thing: creating differentiated reading materials. Paste any text or topic, and Diffit generates reading passages at multiple Lexile levels with comprehension questions, vocabulary, and activities.

Pros

• Best-in-class differentiation: the reading level adaptation is excellent
• Vocabulary support: auto-generates word lists and definitions
• Multiple output formats: passages, questions, graphic organizers
• Simple interface: does one thing and does it well

Cons

• Narrow focus: only useful for reading/ELA differentiation
• Less useful for math, science, specials: reading-focused
• Limited free tier: you’ll hit limits quickly with daily use

Best for

ELA teachers, reading specialists, and any teacher who needs differentiated reading materials regularly.

SchoolAI

What it does

SchoolAI is different: it’s student-facing. Teachers create AI “spaces” where students interact with AI directly, with guardrails. The teacher sets the topic, boundaries, and learning objectives. Students chat with AI to explore concepts.

Pros

• Student engagement: kids love interacting with AI
• Teacher controls: set boundaries on what AI can discuss
• Real-time monitoring: see every student’s conversation
• Unique approach: no other tool does this as well

Cons

• Requires devices: every student needs a computer/tablet
• Classroom management: students can go off-topic despite guardrails
• Not a planning tool: doesn’t help with lesson plans or admin
• Age limitations: less appropriate for K-2

Best for

Teachers who want students to interact with AI directly in a controlled environment. Great for inquiry-based learning, research projects, and Socratic discussions.

Which Should You Choose?

Choose MagicSchool if: you want one tool for planning, admin, and content creation. You’re looking for efficiency across your entire workflow.

Choose Diffit if: you teach ELA or need differentiated reading materials regularly. You want the best tool for one specific job.

Choose SchoolAI if: you want to bring AI into student learning, not just teacher planning. You’re comfortable with students using AI in class.

Choose all three if: they each serve a different purpose. MagicSchool for planning, Diffit for reading materials, SchoolAI for student activities. At $28/month total, it’s less than most textbook subscriptions.

The Free Tier Comparison

All three offer free plans:

	MagicSchool Free	Diffit Free	SchoolAI Free
Generations/month	~40	~15	3 spaces
Enough for daily use?	Barely	No	No
Worth trying free?	Yes	Yes	Yes

FAQ

Can I use MagicSchool, Diffit, and SchoolAI together?

Yes, and they work well as a complementary set. MagicSchool handles planning and admin tasks, Diffit creates differentiated reading materials, and SchoolAI provides student-facing AI interactions. At $28/month total, it’s less than most textbook subscriptions and each serves a distinct purpose.

Which tool is best for elementary teachers?

MagicSchool is best for elementary teachers because of its breadth of tools covering all subjects and grade levels. Diffit is also excellent for K-5 reading differentiation. SchoolAI is less appropriate for K-2 since it requires students to interact with AI independently through typing.

Do any of these tools work for math and science teachers?

MagicSchool has tools for all subjects including math and science. SchoolAI can create math-focused AI spaces for student exploration. Diffit is primarily reading-focused and offers less value for math or hands-on science lessons. For STEM teachers, MagicSchool is the most versatile choice.

Are the free tiers enough for daily classroom use?

Generally no. MagicSchool’s free tier (~40 generations/month) barely covers daily use. Diffit’s free tier (~15 generations) runs out within a week of heavy use. SchoolAI’s free tier (3 spaces) is very limited. You’ll likely need to upgrade the tool you use most within the first month.

How does SchoolAI prevent students from misusing the AI?

Teachers set boundaries when creating SchoolAI spaces: defining what topics the AI can discuss, what it should redirect students toward, and what content to avoid. Teachers can monitor all student conversations in real-time. The AI stays within defined guardrails, though determined students can occasionally go off-topic.
