Hey, I'm Sanjai Kathirvel.

If Claude or ChatGPT stopped working tomorrow, could you still explain why your product works the way it does?

Most of us couldn't.

We ask AI why, it hands us the answer, and we never build the muscle of thinking it through ourselves. Nothing gets practiced. Nothing sticks.

I learned this the hard way.

My manager once asked why this, and not that, about a flow I'd built entirely on Claude. I had nothing. I'd never actually thought it through myself, I'd just shipped the answer.

So every week I break down one real app, copy, or flow, and think it through until it actually sticks.

For PMs, designers, and founders trying to build things people actually will enjoy using it and brag about it.

No paid tier, nothing to sell you.

Still figuring it out myself. If this sounds like you, I'd like to have you here.
