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

Price	Free + $10/mo	Free + $10/mo	Free + $8/mo
Focus	60+ teacher tools	Reading differentiation	Student-facing AI

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
