Quick answer. These four products are not interchangeable. MagicSchool is a wide prompt catalog. Diffit is a fast reading-and-practice pack. Eduaide is a workspace of generators (often 5E-style). MyLesson.AI is a single lesson script plus a teaching pack (quiz, rubric, export) in one thread.
Compare jobs, not logos
Ask which job you are hiring the tool for this week: (1) a full period you will teach tomorrow, (2) a differentiated article + questions, (3) a 5E unit sketch, or (4) a catalog of one-off prompts. Scoring them as if they do the same job produces false winners.
Typical strengths (as of 2026 evaluations)
- MagicSchool: Many educator prompts in one login; calm post-generate editing. Profile setup can be long. Always verify the standard the tool cites.
- Diffit: Fast start, often without an account; strong “Monday packet” (notes, practice, exit ticket). Some export destinations may be gated.
- Eduaide: Rich generator catalog and 5E-style units; check default grade and whether extras (e.g. media) are paid.
- MyLesson.AI: Deep, timed lesson script from one topic field; Pro adds save, export (PDF/Word/PowerPoint), quizzes, and rubrics. First draft is free to create and edit.
Monetization is part of the comparison
Catalog tools often give the first artifact away and charge for volume, seats, or export. MyLesson.AI sells the second create and the pack around the draft (save/export/assess). Neither is hidden “gotcha” if you read the paywall before you recommend a tool to a PLC.
How to run a fair bake-off
Use one prompt (for example: Grade 4 science, states of matter, 45 minutes, lab, groups, exit ticket, ELL support, NGSS). Do not rewrite the prompt to flatter a vendor. Keep the output. Time your edits. Note whether the standard is real for that grade.
Start a MyLesson draft in Create. For assessment add-ons, see Quiz & rubric tools and Pricing.
Citation-ready framing
Thesis. MagicSchool, Diffit, Eduaide, and MyLesson.AI optimize different teacher jobs; a valid comparison uses one shared prompt and scores teachability, not feature count.
