AI for Educators: 3 ChatGPT Features to Use
Most teachers who try ChatGPT for the first time use it the same way: type a question, get an answer, move on.
And then they wonder why the hype is so loud.
The truth is, the features that actually matter for teaching are not the obvious ones. They are tucked underneath the surface, and most educators never get to them because nobody points the way.
This blog does exactly that. Here are three ChatGPT features that are genuinely worth a teacher's time, and what each one can actually do inside a real classroom.
Why Are Teachers Turning to ChatGPT in the First Place?
Before diving into the features, it helps to understand the context.
Teaching has always been demanding. But the modern classroom asks more than ever:
Differentiated instruction for mixed-ability groups
Personalised feedback at scale
Lesson planning that fits curriculum frameworks
Administrative tasks that eat into actual teaching time
Keeping up with students who are already using AI tools independently
The conversation around AI for educators has shifted from "should teachers use this?" to "how do teachers use this well?" That is a meaningful change, and it reflects a growing recognition that AI is not replacing teachers. It is changing what teachers need to know.
ChatGPT, specifically, has built several features that go well beyond basic question-and-answer. Three of them are particularly relevant for anyone who spends time in a classroom.
1. Custom InstructionsÂ
Most people open ChatGPT, type a prompt, and start from scratch every single time.
Custom Instructions change that entirely.
This feature, available on ChatGPT's paid and free tiers, allows users to tell the tool two things upfront:
What you should know about you: Your role, Your context, Your students
How it should respond: Tone, Length, Format, Level of detail
For a teacher, this is transformative. Instead of typing "I am a Year 6 primary school teacher working with mixed-ability students in the UK" at the start of every conversation, that context lives permanently in the background.
What this looks like in practice:
A secondary school English teacher might set their custom instructions to:
Always structure responses as lesson frameworks
Use UK curriculum terminology
Avoid jargon when writing for student-facing materials
Keep explanations suitable for ages 14 to 16
Every response ChatGPT gives is then shaped by those parameters, without the teacher repeating themselves each time.
Why this matters:
It saves time, yes. But more importantly, it makes the output consistently relevant. Generic AI responses are rarely immediately usable in a classroom. Custom Instructions narrow that gap significantly.
Setting this up takes about ten minutes. The return on those ten minutes is every conversation after it.
2. The Memory Feature
Here is a question worth sitting with: how useful is a tool that forgets everything you told it the moment you close the tab?
Not very.
ChatGPT's Memory feature addresses this directly. When enabled, ChatGPT retains information across conversations. It builds a picture of who you are, what you are working on, and what has been discussed before.
For teachers, the implications are practical and immediate:
Tell ChatGPT about a struggling student's learning profile once, and it factors that in every time you ask for differentiated resources
Share your upcoming unit topic, and reference it in future planning conversations
Note that your school uses a specific assessment framework, and responses will align with it going forward
What teachers are actually using this for:
Building an ongoing lesson sequence to support across a term
Getting differentiated resource suggestions that already account for the class profile shared previously
Developing a consistent voice across materials created over weeks, not just one session
One important note:
Memory can be reviewed, edited, and deleted at any time through Settings. Teachers working with sensitive student information should be aware of what is being stored and manage it accordingly. ChatGPT's memory does not store specific student data unless the teacher inputs it, so keeping inputs general is a good practice.
This feature is available on ChatGPT Plus and is being rolled out progressively across accounts.
3. GPT-4o's Vision CapabilityÂ
This one surprises most educators the first time they use it.
ChatGPT's GPT-4o model can analyse images. Not just describe them. Actually, reason about what is in them.
For teachers, this opens up possibilities that text-based AI simply cannot reach:
Marking and feedback support:Â
Upload a photo of a student's handwritten work. Ask ChatGPT to identify where the reasoning breaks down, what misconceptions are present, or how the response could be improved. It reads the handwriting, interprets the content, and responds with specific, actionable feedback points.
Whiteboard analysis:Â
Snap a photo of a mind map, diagram, or brainstorming session from class. Ask ChatGPT to summarise the key themes, identify gaps, or suggest extension questions based on what students have produced.
Resource creation from existing materials:Â
Photograph a textbook page, a past exam question, or a printed worksheet. Ask ChatGPT to create a differentiated version, generate follow-up questions, or adapt the content for a different reading level.
Accessibility support:Â
Convert handwritten or printed content into clean digital text for students who need accessible formats.
This feature is available through the ChatGPT mobile app and web interface when using the GPT-4o model. It works across JPEGs, PNGs, and screenshots, making it genuinely easy to use in a school environment.
Are These Features Enough, or Do Teachers Need Deeper AI Training?
Using ChatGPT features is one thing. Understanding how to use AI strategically across a teaching career is another.
This distinction matters because AI tools are evolving rapidly. A feature that exists today may look very different in two years. What stays constant is a teacher's ability to evaluate, adapt, and apply AI tools critically and confidently.
That is the gap that structured professional development addresses. Institutions like the Asian College of Teachers (ACT) have recognised this and developed programmes specifically designed to build genuine AI competency among educators, not just surface-level tool familiarity.
For teachers who want to move beyond trial and error with AI, exploring what formal professional learning in this space looks like is worth the time. The classroom applications become significantly more purposeful when the underlying understanding is solid.
What Should Teachers Watch Out For When Using ChatGPT?
No honest conversation about ChatGPT in education avoids this question.
A few things teachers should keep in mind:
Accuracy is not guaranteed
ChatGPT can produce confident-sounding, incorrect information. Everything used in a teaching context should be reviewed before reaching students.
Bias exists in AI outputs
Responses can reflect biases present in training data. Teachers should approach AI-generated content with the same critical eye applied to any resource.
Student use is already happening
Whether or not a school has an AI policy, students are using these tools. Teachers who understand them are better positioned to guide their use constructively.
Data privacy matters
Avoid inputting identifiable student information. Keep prompts general when working with class or individual learning data.
AI is a starting point, not a finished product
The most effective use of ChatGPT in teaching is as a first draft or a thinking partner, not a replacement for professional judgment.
These are not reasons to avoid the tool. There are reasons to use it with appropriate awareness.
How Can Teachers Build Real Confidence with AI Tools?
Experimenting with ChatGPT is a reasonable starting point. But confidence with AI in education comes from understanding the broader landscape: how these tools work, where they are heading, what the pedagogical implications are, and how to integrate them into practice in ways that genuinely serve learners.
For educators looking to formalise that understanding, an Advanced Diploma in AI for Educators offers a structured pathway. It moves beyond individual tool tips into the kind of professional knowledge that translates across platforms, across subjects, and across the inevitable changes that AI development will bring.
The teachers who will use AI most effectively in five years are not the ones who know the most features right now. They are the ones building the foundational understanding today.
The Bottom Line
ChatGPT's Custom Instructions, Memory feature, and GPT-4o Vision capability are not gimmicks. They are genuinely useful tools for teachers who take the time to understand them properly.
But tools are only as good as the person using them. AI for educators is becoming a professional literacy, not an optional extra. And the teachers who invest in that literacy now, whether through self-directed exploration or through formal programmes like the Advanced Diploma in AI for Educators from institutions like the Asian College of Teachers, are the ones who will navigate this shift with the most confidence and clarity.
Start with the features. Then build the understanding underneath them.
