Best Free AI Tools for ESL Teachers with No Budget

Teachers in community programmes, churches, volunteer organisations, and small language schools may not have money for monthly software subscriptions.

A useful free tool should help you complete a real teaching task—not simply let you preview a feature that later requires payment.

This guide focuses on ongoing free access, specific features to try, and practical ways to use the results without requiring every student to have a device.

What Counts as Free?

There are three different offers to recognise:

• An ongoing free plan: Core features remain available without a subscription, subject to limits.
• A premium trial: Additional features are available temporarily.
• A limited demonstration: You can sample a feature, but it may not support regular use.

For a zero-budget workflow, build around the first category.

Before committing, check whether you can save the finished material, use it in class, and repeat the task after any trial ends.

Start With the Task You Need

You do not need the whole list. One drafting tool and your usual document editor may be enough.

1. ChatGPT Free: Draft and Revise a Small Activity

ChatGPT provides ongoing free access, with separate limits for some tools and features. Check the consumer-facing Free Tier FAQ rather than relying on an old list of model names or allowances.

For a simple teaching task, start with text chat.

Example: A Café Dialogue

Type:

Review the result, then request a specific correction:

Copy the approved version into your usual document editor.

Keep the Workflow Free

You do not need an image generator, custom assistant, or automated presentation to use this activity. Avoid adding features that do not serve the learning goal.

If an optional feature reaches its limit, use material you already saved or complete the task manually.

Check grammar, vocabulary, instructions, and sample answers yourself. A fluent response is not automatically suitable for beginners.

For more examples, see our ChatGPT beginner’s guide for ESL teachers.

2. Gemini Notebook: Ask Questions About Your Sources

Gemini Notebook is useful when you already have material and want help finding or organising information within it.

Google provides a no-cost Standard option, with limits that differ from upgraded plans. See the official plan comparison.

Feature to Use: Source-Based Chat

Create a notebook and add a short source you have permission to use, such as your own reading passage or unit notes.

Ask:

Then:

Open the citations and compare the response with the original. Google’s chat guide explains how citations connect answers to source material.

Keep the Workflow Free

Begin with a small notebook and source-based questions. You do not need to generate audio, video, or other formats for every lesson.

Source grounding makes checking easier; it does not guarantee that every answer or citation is correct.

Also distinguish summarising from adapting: a concise summary may still contain vocabulary that is too difficult for your learners.

3. MagicSchool Free: Prepare Questions for a Video

MagicSchool offers an ongoing free plan covering core teacher tasks, with usage limits and additional features in paid plans. See its official FAQ.

One concrete starting point is the YouTube Video Question Generator, which builds questions from the transcript of a video.

Example: A Short Community Video

Choose an appropriate clip and watch it yourself first.

Then:

1. Open YouTube Video Question Generator.
2. Paste the video transcript into the tool. If you use the video’s captions to obtain the transcript, check them for errors first.
3. Choose the available question settings.
4. Review the questions against the actual clip.
5. Keep only the questions students can reasonably answer.

For a listening lesson, organise the task around listening:

• First viewing: identify the main idea.
• Second viewing: listen for selected details.
• Follow-up: discuss a related question with a partner.

A transcript-based question generator does not automatically assess visual information, intonation, or everything happening in the video.

Keep the Workflow Free

Check that the activity remains available in your Free account rather than depending on temporary premium access.

Use the reviewed questions on paper or a board if students do not have devices. If the tool is unavailable, the same transcript can support teacher-written questions.

Consult MagicSchool’s current plans for feature differences.

4. Diffit Basic: Adapt a Reading and Save a PDF

Diffit’s Basic plan remains available after premium trial access ends. Its current plan page lists content creation, resource editing and adaptation, and PDF download or printing among Basic features.

Some other export options and advanced features belong to paid plans. Check the official Diffit comparison.

Example: One Topic, Different Support

Start with a short passage you are permitted to adapt.

Keep one final question for everyone:

Use Diffit to prepare an adapted version for learners who need language support. Then:

1. Compare it with the original.
2. Check that important facts remain.
3. Review the vocabulary and questions.
4. Confirm that learners can answer the shared final question.
5. Save the approved resource using the available PDF or print option.

A reading-level setting is not an exact measure of a student’s overall CEFR proficiency.

Keep the Workflow Free

Build your routine around Basic features—not premium export buttons visible during a trial.

Save permitted copies of finished resources rather than assuming your entire resource history will remain accessible indefinitely.

A Useful Companion: Quizlet for Vocabulary Review

Quizlet can help you use vocabulary prepared with an AI tool, but basic flashcards should not be described as an AI feature.

Do not assume that its AI study tools, advanced modes, or document-scanning features are included in free access.

Use Import Instead of Retyping

Prepare a reviewed list with a term and definition on each line. On Quizlet’s website:

1. Select Create → Flashcard set.
2. Choose Import.
3. Paste the terms and definitions.
4. Check the separation and language settings.
5. Review the cards and check visibility before sharing.

Follow Quizlet’s official import instructions.

For review, use Flashcards: ask learners to attempt an answer before revealing the other side, then use the word in a sentence.

If account requirements or feature limits make the activity impractical, use the same list for paper cards or partner quizzes.

A Small Zero-Budget Lesson Workflow

For a reading-and-speaking lesson, you could:

1. Choose an existing reading or draft one in ChatGPT.
2. Review the content and language.
3. Use Diffit only if adaptation is needed.
4. Select a few useful words for review.
5. Prepare a shared pair-speaking task.
6. Save the final material in your normal teaching folder.

You do not need to open every platform.

For a source-heavy unit, Gemini Notebook may be more useful than generating new material. For a video lesson, MagicSchool’s question tool may address the main preparation need.

Choose based on the task, not the number of features available.

For the wider picture — including tools that have paid plans — see our practical AI tools guide, which compares them by the classroom task they solve.

Protect Your Budget and Your Students

Before adopting a free tool, ask:

• Does the task still work after premium access ends?
• Can I save a usable copy?
• Does it require student accounts?
• What happens if access is unavailable during class?
• Does my school approve the service?
• Can students participate without personal devices?

Do not enter confidential records or identifiable student work into unapproved services. Check age requirements and permissions before direct student use.

Free software also has practical costs: internet access, printing, devices, preparation, and troubleshooting. Teacher-only preparation followed by an offline classroom activity may be the simplest option.

Final Thoughts

A zero-budget toolkit does not need to imitate a paid digital classroom.

Start with one recurring task. Use an ongoing free feature, review the result, and save material you can reuse.

The best choice is the tool that helps you prepare something useful without creating costs or access barriers your class cannot manage.
