You start with a clean conversation.

The AI understands your architecture, remembers your requirements, and writes surprisingly good code.

A few hours later, everything changes.

The conversation becomes enormous. The model starts forgetting earlier decisions. It rewrites code you already fixed, contradicts previous implementations, and suddenly needs reminders about parts of the project it understood perfectly an hour ago.

Eventually, the only solution is to open a brand-new chat and spend another 15 minutes explaining your project from scratch.
