Sprout Lessons vs MagicSchool, Khanmigo, Twinkl and Diffit: An Honest 2026 Comparison

Search for an AI teaching tool in 2026 and four names come up again and again: MagicSchool, Khanmigo, Twinkl and Diffit. All four are good at what they were built for, and none of them was built for the same job as Sprout Lessons. This is an honest comparison of all five, organised around the question that actually decides it: what does the tool put in front of the student at the end?

The short version: MagicSchool is an AI toolbox for the teacher, Khanmigo is a chat tutor bolted onto Khan Academy’s content, Twinkl is an enormous library of ready-made resources, Diffit adapts reading passages to different levels, and Sprout Lessons generates a complete interactive lesson for one specific student, aligned to your curriculum, with practice that marks itself. Different artefacts, different jobs.

What each tool actually is

MagicSchool: an AI toolbox for teachers

MagicSchool bundles dozens of small AI tools for educators: lesson plan drafts, rubrics, report comments, IEP paperwork, quiz questions and more, plus Student Rooms where students can use configured AI activities. It has a genuinely useful free tier, with a Plus plan at around US$8 a month billed annually for higher limits. Its centre of gravity is the teacher: most of its output is text and documents for the adult to use, and its standards grounding is built around US frameworks rather than the Australian Curriculum, the Victorian Curriculum or the NSW syllabuses.

Khanmigo: a chat tutor on Khan Academy’s content

Khanmigo is Khan Academy’s AI tutor. For students it behaves like a Socratic chat partner sitting alongside Khan Academy’s existing courses: it nudges, questions and hints rather than answering outright. Teacher tools are free in more than 180 countries through Khan Academy’s Microsoft partnership; the learner plan is a few US dollars a month, with availability centred on the US. Its strength and its limit are the same thing: it works on Khan Academy’s content, in Khan Academy’s sequence, mapped to US grade levels. It does not generate a lesson around your student’s interests or your state’s curriculum.

Twinkl: a library, not a generator

Twinkl is the biggest name in ready-made teaching resources: hundreds of thousands of worksheets, displays, planning documents and activities, with an Australian site whose materials are organised against Australian frameworks. It sells subscription tiers rather than per-resource pricing, and it has been adding AI features around the edges. But the model is fundamentally a library: you search for something close to what you need, print it, and mark it yourself. Nothing in the library was made for your specific student, and the generic-worksheet problem applies in full.

Diffit: reading passages at every level

Diffit does one thing well: give it a topic, an article or a text and it produces levelled reading passages with vocabulary and comprehension questions, so the same content can be read at a Year 3 level and a Year 9 level. There is an always-free tier, with premium exports and extras at around US$15 a month. It is a genuinely useful differentiation tool for reading. It is also deliberately narrow: the output is a passage and questions, usually printed or exported, marked by the teacher, and levelled by difficulty rather than personalised to what a student loves.

Sprout Lessons: an interactive lesson for one student

Sprout Lessons takes a topic, a year level and a student’s interests and generates a complete, playable lesson in seconds: worked examples that do the explaining, self-checking practice with hints, and interactive tools where they genuinely help. Every lesson is grounded in your chosen framework, with seven supported across three countries: the Australian Curriculum v9, the Victorian Curriculum F–10 and the NSW syllabuses in Australia, Common Core and NGSS in the US, and the Ontario, BC and Alberta curricula in Canada. The exact outcome codes are recorded in the lesson footer, and nothing needs marking, because the practice checks itself.

Choose MagicSchool if

• Your bottleneck is teacher paperwork: plans, rubrics, comments, admin drafts.
• You want many small AI tools under one roof with a capable free tier.
• You teach to US standards, which is where its grounding is strongest.

Choose Khanmigo if

• Your students already work through Khan Academy courses and you want guidance on top.
• You want a Socratic chat partner rather than finished lesson material.
• The US-centred grade structure and content sequence fit what you teach.

Choose Twinkl if

• You want a huge searchable library of classroom printables and displays.
• Good-enough generic resources, found fast, beat tailored ones for your workflow.

Choose Diffit if

• Your specific problem is one text that thirty students read at ten different levels.
• You mostly need reading passages with comprehension questions, and marking them is fine.

Choose Sprout Lessons if

• You want the student, not the teacher, to be the one holding the output: an interactive lesson they play, rather than a document you deliver. The difference is the same one we unpack in interactive lessons vs passive worksheets.
• You teach or homeschool against the Australian Curriculum, the Victorian Curriculum, the NSW syllabuses, Common Core and NGSS, or the Ontario, BC or Alberta curricula, and you want the outcome codes recorded rather than claimed.
• You want each lesson built around what the individual child loves, because interests are the gateway to the curriculum, not a distraction from it.
• You never want personalisation to multiply marking: the practice checks itself.

Can you combine them?

Sensibly, yes. These tools compete for your attention, not really with each other. A teacher might draft the term overview in MagicSchool, pull a wall display from Twinkl, level a source text in Diffit, and generate the lesson each student actually works through in Sprout. We make the same argument about general assistants in Claude, ChatGPT or a purpose-built lesson tool: match the tool to the artefact, and most of the confusion disappears.

If the artefact you are missing is the lesson itself, made for one student, aligned to your curriculum and playable in seconds, try Sprout free. New accounts start with free credits, so you can put all five tools side by side on a real topic and judge the outputs yourself.
