The best AI tool for an ESL teacher depends on what needs to happen next.
You might need a listening model for a dialogue, a reading that more students can access, clearer worksheet instructions, or focused pronunciation practice.
Those tasks require different features. A tool that drafts an attractive lesson plan may not provide audio, assess pronunciation, or organise student practice.
Start With Your Teaching Need
| What you need | Tool to explore | Specific feature |
|---|---|---|
| A dialogue and supporting practice | Twee | Create a Dialogue on Any Topic |
| Audio for a reviewed script | Twee | Create Audio |
| A reading with different language support | Diffit | Text adaptation and supporting activities |
| A draft you can revise through conversation | ChatGPT | Text chat and follow-up requests |
| Clear assessment criteria | MagicSchool | Rubric Generator |
| Focused pronunciation practice | ELSA Speak | Model audio, recording, and feedback |
| A language check for written materials | Grammarly | Grammar Checker |
| Vocabulary review | Quizlet | Import and Flashcards; AI features are separate |
You do not need every tool. Begin with one recurring task and check whether the result is useful enough to justify the preparation and review involved.
1. Twee: Create Language Materials Around One Goal
Twee offers named tools for language-teaching tasks, including dialogue creation and exercises built from selected vocabulary.
What to Use
Start with Create a Dialogue on Any Topic when students need a model exchange.
For example, supply these requirements:
Review the draft, remove unnecessary language, and check that the exchange makes sense.
If you need a listening model, use Create Audio for a supported text activity. Twee’s audio instructions explain selecting a voice and generating the recording.
How to Use It in Class
Play the reviewed audio for meaning. Replay useful expressions, let students rehearse, and then have pairs change the order or prices.
The generated audio is synthetic. Preview pronunciation, pacing, and speaker changes before teaching.
A selected CEFR level does not guarantee that every word fits your learners. Give the tool explicit language requirements and review the result.
Access: Check Twee’s current plans. Trial access should not be described as an ongoing free plan.
For more listening-focused options, see our ESL listening practice guide.
2. Diffit: Make a Shared Reading More Accessible
Diffit is worth exploring when students need different support to work with the same topic.
What to Use
Use its resource-creation and adaptation features with a short source you have permission to upload or adapt.
Suppose students will read about transport and answer:
Create an adapted version where necessary, then compare it with the original. Check that important facts remain and that every version supports the final question.
Add vocabulary explanations or sentence starters rather than automatically simplifying every part of the task.
What to Watch For
Reading-level settings are not exact equivalents of overall CEFR proficiency. Simplification can also remove important meaning.
Diffit’s plan comparison distinguishes Basic features, including PDF output, from additional exports and other paid features. Do not assume that every export option is included in your account.
Read the complete workflow in How to Use Diffit for Mixed-Level ESL Classes.
3. ChatGPT: Develop and Revise a Teaching Idea
ChatGPT is useful when your task does not fit a preset form or you want to explore several versions through conversation.
What to Use
Start with text chat and describe the learners, objective, available materials, and desired output.
For example:
After reading the draft, request a focused revision:
OpenAI’s consumer prompting guide explains providing context and refining responses.
What to Watch For
A polished response may contain incorrect explanations, unsuitable vocabulary, or an activity that does not work as described.
Check the output against your learners and source material. Naming a textbook unit does not establish that ChatGPT knows its exact contents.
Access: See the official Free Tier FAQ for current access and limitations.

4. MagicSchool: Draft Clear Assessment Criteria
MagicSchool organises its tools around teaching tasks. One useful entry point is its Rubric Generator.
What to Use
Provide the assignment and the learning objectives rather than requesting a generic speaking rubric.
For example:
Review the descriptors and try applying them to a sample response.
What to Watch For
A rubric can look professional while assessing things the students were never taught.
Replace vague labels such as “excellent vocabulary” with descriptions learners can understand. For a simple task, a short checklist may be more useful than a detailed rubric.
Access: Check MagicSchool’s current plans. Individual teacher access and institutional features are not the same.
5. ELSA Speak: Support Focused Pronunciation Practice
ELSA is relevant when a learner needs opportunities to hear, produce, and review a particular pronunciation feature.
What to Use
Choose a relevant pronunciation lesson. ELSA describes model-audio and student-recording comparison in its feedback guide.
Have the learner:
- Listen to the model.
- Record the target language.
- Replay and compare.
- Choose one useful adjustment.
- Try again.
- Use the language in an original response.
What to Watch For
Do not turn practice into a search for a perfect score. Focus on intelligibility and differences that affect communication.
Younger learners may need close guidance to navigate activities and understand feedback.
An individual app account does not automatically provide a teacher dashboard. Evaluate ELSA Schools separately if class management is required.
Access: See individual subscriptions or request institutional information through ELSA Schools.
Read our ELSA Speak classroom review and pronunciation-tool comparison.
6. Grammarly: Check Written English Selectively
Use Grammarly’s Grammar Checker for an additional language check on instructions, messages, and teaching materials.
What to Use
Review a completed draft, consider each suggestion, and keep changes that improve accuracy without increasing difficulty.
For student writing, an appropriate teacher-guided task might be:
What to Watch For
A rewrite may change the learner’s meaning or introduce language they cannot explain.
Also keep deliberate errors in editing exercises separate from ordinary proofreading. The checker may “fix” the item students are supposed to correct.
Grammarly does not verify your facts, answer key, or learning objectives.
Access: Consult Grammarly’s plans. Do not equate individual free access with an institutional education agreement.
7. Quizlet: Turn Reviewed Vocabulary Into Practice
Quizlet can support an AI-assisted workflow, but its basic flashcard functions should not be confused with its AI features.
What to Use
Prepare and review a term-definition list, then use Import on the website to create a set. Follow Quizlet’s import instructions.
Use Flashcards for recall practice: students attempt an answer before revealing the other side, then use the word in a sentence.
What to Watch For
Public sets and AI-generated definitions can contain errors. Check meanings, translations, and examples before assigning them.
Do not assume every study mode or AI feature is free. The reviewed vocabulary list can also become paper cards or a partner quiz.

Choose for Your Classroom, Not Just the Feature List
For young learners, prioritise teacher-led use, clear listening models, and short tasks. Avoid making independent account navigation part of the learning challenge.
For teens and adults, consider language level and self-management as well as age. An advanced feature is only helpful if the learner understands what to do with it.
For whole classes, check devices, headphones, noise, access arrangements, and teacher monitoring.
For small groups or tutoring, a simple shared task may be more practical than a full institutional platform.
Before direct student use, review age requirements, privacy terms, consent arrangements, and school approval. Provide an alternative for learners who cannot use the service.
Build One Complete Learning Sequence
A useful AI-supported lesson might follow this pattern:
- Choose a language objective.
- Prepare and review a model.
- Help students understand and notice useful language.
- Provide guided practice.
- Move into a task with a genuine choice of meaning.
- Give focused feedback and another opportunity to try.
The sequence matters more than how many tools appear in it.
For conversation-focused choices, see our ESL speaking practice guide. For teacher language support, see AI tools for non-native English teachers.
Final Thoughts
Choose the feature that addresses a real teaching need, test it on a small task, and include review time in your evaluation.
Keep the tool if it helps you prepare appropriate materials or gives students useful practice. Leave it out when it adds complexity without improving the lesson.
AI can supply drafts, models, and practice opportunities. The teacher connects them to learners, purpose, and meaningful communication.
