Modern AI-powered writing assistants like Grammarly, Quillbot, and ChatGPT promise to fix your grammar instantly and make your English writing better. But do these tools actually help students learn English, or are they just digital crutches?

Let’s take a sober look at both sides of the story.

What AI Writing Assistants Do Well

1. Catching Obvious Mistakes

Missing articles, wrong verb tenses, or spelling errors—AI is great at spotting these. A student who writes “She go to market yesterday” will get an instant suggestion: “She went to the market yesterday.” That’s feedback in real time, faster than a teacher can mark homework.

2. Boosting Confidence

Students often feel embarrassed about their writing. With AI, they can test ideas privately before sharing with others. It’s like whispering your English to a friendly robot before speaking to the class.

3. Expanding Vocabulary

Some tools suggest alternative words or phrases. If you keep writing “good,” the assistant may nudge you towards “excellent,” “outstanding,” or “effective.” For learners stuck in the land of “nice” and “very,” this can be refreshing.

4. Saving Teachers’ Time

Let’s be honest: correcting piles of essays is exhausting. With AI handling the basic grammar issues, teachers can focus on deeper aspects—like argument structure, creativity, and critical thinking.

The Pitfalls Nobody Talks About Enough

1. Passive Learning

If a tool fixes every mistake for you, are you really learning? Students often just click “accept” without understanding why the correction is made. Imagine trying to learn to cook by watching someone else stir the soup, but never holding the spoon yourself.

2. Over-Polishing

AI tends to make student writing sound… well, a bit robotic. Everyone starts producing the same “perfect” sentences, stripped of personality. The joy of language is in its quirks and creativity, and AI doesn’t always respect that.

3. False Confidence

AI sometimes gives wrong suggestions—very confidently. I’ve seen tools insist on changing perfectly correct sentences into nonsense. A student who blindly trusts the machine may end up less accurate than before.

4. Dependence

Here’s the danger: once you rely on AI for every sentence, writing without it feels impossible. Just like calculators made some students forget their multiplication tables, AI might make you forget how to write a simple paragraph on your own.

How to Use AI Wisely in English Learning

So, should we embrace AI or run away from it? At the Thai language tutoring company BestKru English, where I teach, we choose neither. We use it — but wisely. Here are some simple guidelines on AI we give to our teachers and students:

1. Use It as a Mirror, Not a Crutch

Treat AI feedback like looking in a mirror: it shows you what’s wrong, but you still have to fix your hair yourself. When AI corrects your grammar, don’t just accept it—write down why the change was made. This builds awareness.

2. Set Boundaries

Don’t let AI rewrite your entire essay. Use it for grammar checks, not for generating full paragraphs. If you let it do all the heavy lifting, your muscles (a.k.a. your writing skills) won’t grow.

3. Compare Versions

After AI makes suggestions, compare them with your original. Ask yourself: Which one do I like more? Which one sounds more like me? This keeps your voice alive.

4. Teachers Should Guide, Not Ban

Some teachers panic and ban AI altogether. I think that’s like banning calculators in a math class—unrealistic. Instead, teach students how to use AI critically. For example:

• First, write an essay without AI.
• Then, run it through AI and analyse the differences.
• Finally, reflect: What did I learn?

This process turns AI into a learning partner, not a lazy shortcut.

5. Focus on Output Beyond Writing

Remember: writing is not the final goal. Communication is. Students should still read books, join discussions, and speak in real contexts. No AI can replace that.

Final Thoughts

So, do AI-powered writing assistants really help students learn English?

• Yes, if they are used as guides, mirrors, and practice partners.
• No, if they are used as shortcuts, ghostwriters, or unquestioned authorities.

The choice is in our hands. Let’s not fear the machine, and let’s not worship it either. Instead, let’s teach students—and ourselves—how to stay human while using the smartest tools we’ve ever built.

And remember: your English doesn’t need to be perfect to be powerful. Even Shakespeare broke grammar rules. I doubt any AI would have let him get away with “To be or not to be” without suggesting a smoother sentence. But luckily, he didn’t listen.
