The Hidden Cost of Linear Thinking

Current AI chat forces you into a single thread. Your best ideas get buried, and you're stuck with whatever the AI agrees with.

Lost in the Thread

20+ messages deep, that brilliant insight from message #7 is practically gone. Linear chat wasn't built for complex thinking.

The Sycophancy Problem

AI models are trained to agree with you. Single-model conversations reinforce biases instead of challenging assumptions.

One Shot, One Path

Explore an alternative? Start over. Compare approaches? Open new tabs. Current tools force linear thinking in a non-linear world.
