ActivitiesComparing the Top ESL Activity Generators for Teachers
I spent three weeks using five different AI-powered ESL activity generators for every class I taught. Same topics, same levels, different tools. By the end, I had strong opinions about which ones are worth the money and which ones waste your time. Here's the honest breakdown.
The Five Tools I Tested
ChalkLab -- Best Overall for ESL-Specific Activities
What it does well: Generates complete, structured activities with correct CEFR-level vocabulary. The output includes warm-up, main activity, and follow-up components. Understands the difference between a B1 gap-fill and a C1 gap-fill without you having to explain it.
Where it falls short: Smaller template library than MagicSchool. Fewer non-ESL features.
Best for: Teachers who need ready-to-use ESL activities without heavy editing.
MagicSchool AI -- Best Template Variety
What it does well: Over 60 templates covering every possible teaching need. The ESL-specific templates are solid, and the general education templates (rubric makers, assessment generators) add value if you teach in a school setting.
Where it falls short: Some ESL output needs level adjustment. I got B2 vocabulary in an A2 activity once. The templates guide you, but they don't guarantee ESL-appropriate results.
Best for: Teachers who need variety beyond just ESL activities -- rubrics, assessments, parent communication.
Twee -- Best for Content-Based Activities
What it does well: Excels when you have source material. Paste an article or YouTube link, and it builds vocabulary, comprehension, and discussion activities around that content. The text-to-activity pipeline is smoother than any other tool.
Where it falls short: Less useful when you're starting from scratch with just a topic and level. It needs input content to work from.
Best for: Teachers who build lessons around texts, videos, and authentic materials.
ChatGPT -- Best Free Option (with Caveats)
What it does well: Completely free tier available. Generates ideas fast. Flexible -- you can ask for literally anything. Good for brainstorming when you're stuck.
Where it falls short: Doesn't understand CEFR levels reliably. Output requires more editing than purpose-built tools. No ESL-specific templates, so your prompt quality determines your output quality. I've gotten activities that would work for native speakers but completely miss the mark for ESL learners.
Best for: Teachers on a zero budget who are comfortable writing detailed prompts.
Diffit -- Best for Reading and Leveling
What it does well: Takes any text and creates multiple leveled versions with vocabulary support. The reading comprehension activities are strong. Perfect for mixed-level classes.
Where it falls short: Focused on reading. Not the right tool for speaking, listening, or grammar activities.
Best for: Teachers who need differentiated reading activities for mixed-level classes.
The Quick Comparison
If I could only pick one: ChalkLab for ESL-specific activity generation. If I could pick two, I'd add Twee for content-based lessons. If budget is zero, ChatGPT with carefully crafted prompts gets you 70% of the way there.
Every tool on this list will save you time. The question is which one saves you the most time for your specific teaching context.
