Why Not Just Use ChatGPT for Lesson Planning?
Fair question.
If you can use ChatGPT for lesson planning—generating lesson ideas, activities, rubrics, explanations, worksheets, and student instructions—why use something like CARL?
Honestly, sometimes ChatGPT might be enough.
If you need a quick idea, a wording tweak, a list of possible activities, or help getting unstuck, a general AI chat tool can be genuinely useful. I use AI all the time for brainstorming, organizing ideas, and turning messy thoughts into something usable. It’s saved me more times than I can count.
But lesson planning isn’t just “ask for a lesson and copy the answer.”
At least, it shouldn’t be.
The issue isn’t whether ChatGPT can produce something. It can. The bigger question is whether a blank chat window gives you the kind of workflow that actually supports curriculum, learner needs, accessibility, assessment, classroom context, and all the pieces that come after the basic lesson outline.
That’s where CARL is trying to do something different.
ChatGPT for Lesson Planning Can Help, But Prompting Is Work
Prompting makes up probably 95% of what I talk about when I facilitate PD workshops on using AI for lesson planning.
In my Beyond the Basics Planning Workflow session, I give participants a working prompt file that’s more than 60 pages long. It breaks down the whole process: reusable profiles, curriculum alignment, learning goals, unit plans, lesson structure, accessibility supports, ELL/EAL scaffolds, assessment options, reflection prompts, extension activities, student-facing instructions (and more!).
That file exists because using ChatGPT for lesson planning can help, but good results often take more than one prompt. Prompting is absolutely a skill anybody can learn, but it also takes time.
You have to explain what you want. Then you often have to explain the curriculum, class context, learner needs, assessment style, reading level, accessibility supports, and the format you actually need.
And then, of course, you still have to check, edit, organize, and make sure it fits your class.
That can work. I teach people how to do it. But it’s work.
We’re not keeping CARL’s “secret sauce” locked up in a safe. What we’re doing is building those prompts, supports, structures, and teacher decision points into a guided workflow, so you’re not starting from a blank chat or working your way through a 60+ page document every time.
Topic and Grade Aren’t Enough
A lot of AI lesson planning starts with two questions:
“What’s the topic?”
“What’s the grade?”
That’s a start, but it’s not enough to make a lesson truly tailored.
A Grade 6 ecosystems lesson can look very different depending on the curriculum, class profile, time available, materials, language supports, accessibility needs, student interests, and the teacher’s goals. The same topic could become a hands-on inquiry lesson, a discussion-based lesson, a visual organizer activity, a project launch, or a review lesson.
Those choices aren’t tiny details. They shape the lesson.
A blank prompt can generate content, but it doesn’t know what matters most in your classroom unless you take the time to explain it. And the more context you have to type, check, and retype, the more the “time-saving” starts to feel a little questionable.
CARL is built to bring more of that context into the workflow from the beginning: subject, grade level, curriculum, lesson length, learning goals, learner needs, accessibility considerations, ELL/EAL supports, and details from a Saved Class Profile.
That doesn’t mean CARL magically knows everything. It still needs your input, your review, and your professional judgment.
But it starts from more than a topic and grade level, which gives you a better starting point.
A Guided Workflow Is Different from a Blank Chat
General AI tools can be great for brainstorming, drafting, rewriting, simplifying, and exploring ideas. They can help you get unstuck quickly. They can offer options you may not have thought of yet.
But there’s a difference between a helpful chat and a guided planning workflow.
A guided workflow should help you bring in the context that matters, think through what comes next, and connect the lesson outline with the supports, assessments, and student-facing materials that make it usable. Learn more about what classroom-ready actually means.
It should also make teacher review easier, not heavier.
That’s the gap CARL is trying to close.
So maybe the better question isn’t “Why not just use ChatGPT?”
Maybe it’s: What kind of planning workflow actually helps?
If you need a quick idea, ChatGPT may be enough.
If you need planning support that connects classroom context, curriculum, student supports, assessment options, and teacher review, CARL is being built for that bigger workflow.
AI can still be part of the process.
It just doesn’t have to leave you doing all the organizing, prompting, checking, adapting, and rebuilding alone.
The Bottom Line
- ChatGPT can be useful for brainstorming, drafting, and getting unstuck quickly.
- But strong lesson planning often takes more than one prompt—it takes context, structure, and teacher decision-making.
- CARL is built to bring classroom context, planning supports, and guided review into one workflow.
- AI doesn’t have to mean starting from scratch every time.
AI is part of the process—but CARL is designed to make that process more useful, more connected, and more teacher-led.
