The Future of TEFL in 2025: How Open-Source Tools & AI Are Revolutionising English Teaching
Continuing in my TEFL (TEACHING ENGLISH AS A FOREIGN LANGUAGE) series, last week I blogged about the best online TEFL courses in 2025 and beyond. If you follow me, you’ll hear me regularly say that taking my TEFL, and then teaching English in Thailand and Korea COMPLETELY changed my life. It was the best choice, aside from starting my blog perhaps, I made in my professional life. Today, i will look at the future of TEFL. To see if what worked before, still works, and what the future looks like.

So, you’re thinking about teaching English, travelling the world, or maybe just escaping the 9–5 grind. Welcome to TEFL in 2025, where things are moving fast and in a seriously exciting direction.
We’re not just talking Zoom classes anymore. Thanks to AI-powered platforms and open-source TEFL tools, getting started is faster, cheaper, and smarter than ever. Whether you want to teach online, move abroad, or stack a meaningful side hustle, the opportunities are real and they’re growing.
Let’s break down how these providers, and especially open-source tech, are changing the teaching game for good.
Why Open-Source TEFL Tools Are Changing the Game
The old way of getting TEFL-certified? Buy a course. Read a PDF. Hope for the best.
The 2025 way? Open-source lesson libraries, AI-generated resources, and collaborative teacher communities that evolve in real time.
Here’s why open-source matters:
Free access to constantly updated teaching materials
Crowd-sourced lesson plans from real teachers worldwide
AI-powered tools for creating quizzes, worksheets, and feedback
Community forums for support, hacks, and job tips
Transparent course comparisons with verified reviews
If you’re not using open-source TEFL resources, you’re basically teaching with a flip phone in a smartphone world.
My TEFL Journey: From Gap Year to Global Career
When I first signed up for a TEFL course, I thought it’d just be a quick gap year. Teach a bit, travel, then move on. But that one decision flipped my life completely.
I signed up for my TEFL, studied it and moved to teach in Chiang Mai, Thailand. From day one, I realised I was free. A TEFL course allowed me to dream of living in any country I wanted. The cultureS, the people, the energy it just so exciting. Within a month, I got a full-time teaching job, settled in, and never looked back.
Sharing travel tips turned into a side hustle. I’ve spoken at international panels, built a following online, and yep, my TEFL journey even got cited on Wikipedia.
TEFL wasn’t just a travel phase. It was the best decision I’ve ever made. It changed my life. In my opinion, it’s the best way to take the first steps into an international life. You never know where you’ll end up.
So let’s have a look at some of the leading TEFL providers…

As you know, blogging changed my life. I left Ireland broke, with no plan, with just a one-way ticket to Thailand
and no money. Since then, I started a blog, then a digital media company, I've made
more than $1,500,000 USD, bought 4 properties and visited (almost) every country in the world. And I did it all from my laptop as I
travel the world and live my dream. I talk about how I did it, and how you can do it too, in my COMPLETELY FREE
Ebook, all 20,000
words or so. Just finish the process by putting in your email below and I'll mail it right out to you immediately. No spam ever too, I promise!
Take ownership. Take action, and remember
