Hey friends,

You can now chat with every Weekly I/O I’ve ever sent:

https://chengweihu.com/io-chat

620+ inputs and ideas, one question away!

I’ve been using it as a thinking partner, asking things like “what should I consider before making this decision?” or “what are some psychological explanations of X?”, and it pulls together threads from across years of Weekly I/O’s issues I’d long forgotten about.

It’s become a surprisingly nice way to revisit and actually apply what I’ve learned over the years.

If you’re a paid supporter, you can log in with the same email you use for Substack and your account will automatically get more chat usage. I hope this becomes a useful way to explore ideas whenever you’re thinking through a question or decision.

Happy learning,

Cheng-Wei

P.S. I also recently built a new Mac tool to help you learn by doing (perhaps you can try build your own Weekly I/O chat!).

You can try it here with access code weeklyio: https://mouseover.ai
