Is Lesson Ninja for me?
Lesson Ninja is designed as an aid to teaching foreign languages, so it will benefit any teacher who wants to make their gap-fill and matching exercises more exciting without forcing their students to register/log on.
Our app might be life-changing for teachers who tend to individualize the content of their courses, especially those who use authentic materials or retrieval practice in their class. People who create their own teaching materials willl find it extremely useful, too.
There are many other platforms. Why Lesson Ninja?
Lesson Ninja's functionalities bridge the gap that none of other platforms have. It's the only tool out there whose main purpose is to limit teachers' prep time. It's also packed in a minimalistic, clutter- and ad-free layout, and doesn't require your student to log in. Finally, it's made entirely DIY by two teachers, with a strong conviction it will make your life better.
Can I get a tax invoice?
Yes, but only in case of a yearly subscription. After you subscribe send us an email with your company details.
What's your cancellation policy?
You can cancel any time and use the tool until the end of the current billing period. You can manage your subscription by navigating to my account → manage billing.

Here's what other teachers say...
A wonderful tool that has been helping me prepare great and strongly motivating warm-up and revision activities, thereby making my classes effortlessly more varied and fun. A range of useful options, such as wordpool and time limits, allows for adjusting each activity to different students' levels if needed. On top of that, the website's simple, minimalist design is really pleasant and user-friendly.– Anna
I’m at a loss for words at how useful and time-saving Lesson Ninja is for me. It takes me seconds, literally, to prepare a good exercise which draws my students’ attention to the important grammar or vocab topics they need to focus on. Lesson Ninja site is a dream come true for me as a teacher. User-friendly options - both for teachers and their students - only add to the uniqueness of the site. It’s definitely worth recommending to those who are in need of more pleasure and less drama in their lesson preparation time.– Magda
Lesson Ninja is an utterly convenient tool to turn authentic materials into engaging class materials instantaneously! I've been enjoying it to the fullest only after a few trial-attempts thanks to its very simple layout. It's even simpler for my students as they can practice materials using just a single link. As an EFL teacher who enjoys preparing up-to-date content for learners, I love it when time-consuming details of material preparation are minimized, and Ninja does exactly that!– Mustafa
