How to choose

1.Standards alignment is the key feature: plans mapped to your curriculum standards save real rework.
2.Differentiation support matters for mixed-ability classrooms — look for tools that generate variations, not one generic plan.
3.All-in-one teacher platforms earn their place when you also need quizzes, worksheets, and IEP-related documents.
4.If lessons should become interactive digital content, pick an authoring platform over a document generator.
5.Review AI plans against your students' reality: pacing and prerequisites are where generated plans most often miss.
