Lesson Ninja comes with a 14-day free trial. No need to put any credit card info upfront. If you decide to stay with us afterwards, we charge an amount equal to two lattes.
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?

What's your cancellation policy?

Here's what other teachers say...
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
Lesson Ninja is a fantastic tool for language learning. It's simple and intuitive on both ends (for students and teachers). I really appreciate the option to have customized links to different versions of the same set (test mode, with/without wordpool or timer etc.) without multiple unnecessary copies of the set itself. The "randomize" option is great for speaking prompts and discussion questions. I highly recommend including it in your classes.– Agnieszka
The whole thing looks cool, slick, and modern. It’s been a week and I already know I’ll be a regular user. With Ninja, I prepare revision for my students almost automatically, in max 10 minutes. My students feel that I’m extremely well-prepared as they see their own words and phrases in the link. In the digital era, such solutions are a hit.– Basia
