Critical thinking course
Why do smart people fall for bad arguments?
Work it out in conversation with your own AI tutor in the Epivo app.
Let's start with something you hear every day. Someone says: you should get more sleep, because tired people make worse decisions. So here's my first question for you. Is that an argument, or just an opinion? Tell me what you think, and we'll see where it leads.

How it works
- Your tutor starts from an everyday claim, then hands you one small puzzle about it: what's the reason, and does it hold?
- You think it through, out loud or by typing. You don't need to know the answer: your tutor helps you along and tells you when you're close.
- Step by step, it adds up. Your tutor remembers your past sessions and what you've shared, and picks up where you left off.

How to spot an argument, and find the step it quietly takes for granted

Questions
Is it really free?
Yes. Thirty minutes a day with your tutor, and no card. Paid plans add more time if you ever want it.
Is my tutor a real person?
No. Your tutor is an AI that talks with you, follows a planned course and remembers your past sessions.
How do I know the lessons are accurate?
Written lessons are fact-checked against independent published sources before they're taught. Your tutor follows a planned route through the course, and the app's Sources menu lists what each session drew on, including links to the original sources.
How is this different from asking ChatGPT?
ChatGPT answers what you ask. Your tutor leads the way: a planned route through critical thinking, one question at a time, picking up where you left off.
Will it help me make sense of the news?
Yes. Whole parts of the course look at how headlines use numbers, how your social media feed decides what you see, and how to check a story or a photo before you share it.
Does it cover cognitive biases?
Yes. One part of the course is about the mental shortcuts everyone takes, like noticing only what fits what we already believe, or sticking with a plan because we've already paid for it, and simple habits for catching them in yourself.
Is it on iPhone?
Not yet. Epivo runs on Android today. Open this page on an iPhone and you can leave your email; we'll tell you when the iPhone app is ready.
Start with one everyday claim. Work out the rest together.
