Most people use an AI assistant to fix their English like this: paste in an email, ask it to “correct it”, copy the result and send. It works, in the sense that the email is better. But you learn nothing, and next week you will make the same mistake again.
A small change in how you ask turns the same tool into something closer to a patient reviewer. Instead of asking for a correction, ask for an explanation.
The basic prompt
Here is one you can copy and adapt:
“Please look at the text below. Don’t rewrite it. Underline or list each mistake, explain in simple English why it is wrong, and give one corrected example. My level is B2 and my first language is [your language]. Text: …”
Three things in that prompt matter. “Don’t rewrite it” stops the tool from quietly replacing your text. “Simple English” keeps the explanations readable. And naming your level and first language lets the assistant guess where your habits may come from.
A worked example
Suppose you write this:
“I am working here since three years and I have responsibility of the budget.”
A good reply might look like this:
- “I am working here since three years”: with a period of time that continues until now, English uses the present perfect continuous. Also, “for” goes with a length of time and “since” goes with a starting point. Correct: “I have been working here for three years.”
- “responsibility of the budget”: after “responsibility” we normally use “for”. Correct: “I have responsibility for the budget” or, more naturally, “I’m responsible for the budget.”
Now you have the rule, not just the fixed sentence. You can write your own example straight away: “I have been learning English for two years.”
Ask for patterns, not just errors
After a few texts, try this:
“Here are five short texts I wrote this month. What are my three most common types of mistake? Give me one rule and one exercise for each.”
This is where an assistant can save real time. It can spot that you keep dropping articles, or that you mix up “since” and “for”, and turn that into a short practice plan.
Ask it to check its own explanation
AI assistants can be confident and wrong. They sometimes invent rules, give examples that don’t quite fit, or explain a mistake that you didn’t make. So build in a check:
“Are you sure? Please give two more example sentences using this rule, and tell me if there are exceptions.”
If the examples contradict the rule, or the explanation seems odd, check a learner’s dictionary or a grammar reference, or ask a teacher. Treat the assistant like a helpful colleague who is usually right, not like an authority.
Other useful prompts
- For tone: “Is this email too direct for a first message to a client? Explain which phrases sound strong and suggest softer options, but keep my version as the starting point.”
- For vocabulary: “I wrote ‘we will realise the project in June’. Does ‘realise’ sound natural here? What would an English speaker say?”
- For practice: “Give me five gap-fill sentences testing the mistake I just made. Don’t show the answers until I reply.”
Be careful what you paste
Before you paste any text into an AI tool, remove anything private: client names, figures, contract details, personal data. Check your employer’s rules too. Many workplaces have a policy on what may be shared with external tools. If in doubt, replace names with “Company A” and numbers with “X”. The grammar lesson is the same.
What it can’t do
An assistant won’t hear your pronunciation, notice that your pauses are making a meeting awkward, or tell you that a phrase is technically correct but not what people say in your industry. A person who knows you can do those things. It is a useful partner between lessons and a good way to practise writing, but it doesn’t replace everything.
