“Generate a lesson” can mean several different things.
One tool produces a teacher’s plan with objectives and stages. Another creates readings and worksheets. A third builds an interactive lesson that students join on their devices.
Before choosing an AI lesson plan generator, decide which part of preparation you need help with.
For ESL teachers, a useful result should support a clear language goal, fit the learners’ age and proficiency, and include opportunities to use English — not simply produce a long list of activities.
This guide compares documented features and suggests practical uses. The examples are planning suggestions, not results from a controlled comparison of the platforms.
First, Decide What You Need
| Your main need | Platform and starting point | What it helps you prepare |
|---|---|---|
| A structured teaching plan | MagicSchool: Lesson Plan Generator | Objectives, lesson stages, and assessment ideas |
| Language activities or an existing ESL lesson | Twee: ESL Lesson Plans library and individual tools | Dialogues, readings, exercises, and lesson content |
| Differentiated materials around shared content | Diffit: resource creation and Diffit Chat | Adapted readings, scaffolds, activities, and lesson components |
| A teacher-led interactive lesson | Curipod: lesson creation | On-screen activities, student responses, and discussion |
These platforms overlap, but they do not produce identical results. A detailed plan may still need student materials. A complete worksheet may still need a teaching sequence.
1. MagicSchool: For Building the Lesson Structure
MagicSchool’s Lesson Plan Generator creates a plan from information such as the topic, learning objective, learner context, and available time.
It is a useful starting point when you know what students should learn but need help organizing the lesson.
What to Enter
Include the students’ age and English proficiency, the language they already know, the lesson length, and the final task. For example:
Do not rely on a grade-level selection alone. School grade and English proficiency describe different things.
What to Do Next
Review the sequence, then identify any missing materials. If the plan mentions a reading, role card, or worksheet, check whether that material has actually been created.
MagicSchool’s Worksheet Generator can help draft the student handout. Its Presentation Generator can help prepare slides when you need visual support.
You do not have to use all three. A short speaking lesson may only need a plan and two role cards.
2. Twee: For Language Activities and Adaptable ESL Lessons
Twee offers two useful starting points: an existing lesson or individual activity generators.
Start With an Existing Lesson
Open the ESL Lesson Plans library and filter by CEFR level, age, skill, topic, duration, and individual or group format.
Choose a lesson that fits your objective, then review the vocabulary, instructions, and final task. A matching level label does not mean every activity will suit your learners.
This route is useful when you want an existing sequence to adapt rather than a blank planning page.
Build Selected Activities
If you already have a lesson structure, use specific tools instead:
- Create a Dialogue on Any Topic for a model exchange.
- Find Discussion Questions for prompts connected to a topic or text.
- Fill in the Gap for controlled practice using reviewed language.
For the weekend-planning lesson, create a dialogue in which two friends compare activities. Remove selected expressions for guided practice, then give students different choices for their own conversation.
The final task should require a genuine decision, not simply reading the model aloud.

3. Diffit: For Differentiated Lesson Materials
Diffit is useful when students need different support to work with the same content.
Its current scope extends beyond text simplification. The official Quick Start guide includes lesson kits, station rotations, writing activities, task cards, and other instructional resources.
Start with a topic or existing material, explain what students need, and refine the result using Diffit Chat. You can request changes to reading level, activities, or supporting materials. See the official workflow.
A Practical Starting Request
For the weekend-planning lesson, provide two short descriptions of local activities and ask:
Then review the materials and adjust the support for different learners.
Some students might receive definitions and sentence frames. Others might compare the options without those supports. Everyone can still finish by choosing an activity and explaining why.
For more detail, see How to Use Diffit for Mixed-Level ESL Classes.
4. Curipod: For Teacher-Led Interactive Lessons
Curipod is a different kind of planning tool. Its lessons combine teacher-led instruction with student participation, including activities such as polls, open responses, and discussion. Its current website particularly emphasizes reading, writing, and feedback. (Curipod overview)
This can be useful when you want to see students’ thinking during the lesson rather than only collect a worksheet afterward.
How to Start
Use Curipod’s lesson-creation options to enter a topic and explain the learning goal. Its official lesson-creation example shows a topic prompt with optional curriculum material.
For an ESL lesson, include the language level and response expectations. For example:
Review the generated activities before presenting them. Reduce reading demands if students need more time, and check whether feedback is understandable at their English level.
Students join a teaching session through a join code. Test access on the devices available in your classroom. (Curipod’s teaching-session guidance)
Comparing the Same Lesson Goal
Suppose the objective is:
Students can compare two weekend activities, give a reason, and agree on a plan.
Each platform offers a different way to prepare:
| Platform | Suggested use for this lesson |
|---|---|
| MagicSchool | Draft the teaching stages and success criteria |
| Twee | Create a model conversation and targeted language practice |
| Diffit | Adapt activity descriptions and add comparison support |
| Curipod | Collect choices and explanations during a teacher-led lesson |
You do not need all four. Choose the one that addresses the part you would otherwise spend the most effort preparing.
If you already have a good lesson plan, generating another plan may add little value. Creating clearer role cards or better support for one group may be the more useful task.
What Every Generator Needs From You
Whichever platform you choose, provide these details:
- Learners: Age, proficiency, and relevant experience.
- Objective: What students should communicate or understand.
- Prior language: Vocabulary and structures they already know.
- Conditions: Time, class size, equipment, and grouping.
- Final task: What students will do to demonstrate learning.
Ask for manageable outputs. A clear plan with a model and a purposeful final task is often more useful than ten disconnected activities.
For a detailed planning process, see How to Generate CEFR-Aligned Lesson Plans with AI.
Before You Teach the Generated Lesson
Check that:
- The instructions are understandable.
- The lesson fits the available time.
- Referenced materials and answer keys are included.
- Vocabulary and task demands suit the learners.
- Students have meaningful opportunities to use English.
- The final task checks the stated objective.
- Digital activities work with your equipment and school requirements.
Do not upload student names, confidential records, or material you do not have permission to use.
After teaching, note what needed changing. Those observations will help you improve the next version more effectively than repeatedly generating new plans.
Final Recommendation
Choose MagicSchool when you need help organizing the lesson.
Choose Twee when you need language-specific activities or an existing ESL lesson to adapt.
Choose Diffit when shared content needs different levels of support.
Choose Curipod when you want a teacher-led interactive lesson with visible student responses.
Check current plans and feature access on the official pricing pages: MagicSchool, Twee, Diffit, and Curipod.
The best AI lesson plan generator is the one that helps you prepare the missing piece of a suitable lesson — not simply the one that produces the most content.
