cognitive mode: on

Your AI is doing the thinking.
You're just doing the typing.

Break the cycle of mindless prompt-engineering. Introduce intentional friction into your development workflow to rebuild your cognitive problem-solving muscles.

How do I reverse a linked list in JavaScript?

Here's a clean iterative approach: function reverse(head) { let prev = null, curr = head; while (curr) { [curr.next, prev, curr] = [prev, curr, curr.next]; } return prev; }

What's the time complexity?

O(n) time, O(1) space — it visits each node once without any additional data structures.

Before you ask the AI — articulate your thinking. Both fields required to unlock.

1. What is your hypothesis?

2. What have you already tried?

Fill both fields and wait for the timer

why it works

Three mechanisms. One goal.

Rebuild the habit of thinking independently — without quitting AI entirely.

Intentional Speedbumps

Prevent instant code-generation offloading with customizable delay loops. Control exactly how long your brain has to sit with the problem before the AI gets involved.

The Hypothesis Gate

Force your brain to articulate what you are trying to solve before asking an LLM. Typing it out often solves the problem before you ever hit send.
