ChatGPT is the most general-purpose AI on the planet — it can draft a meal plan, summarise a paper, write SQL, debug code, explain quantum mechanics. Versatility is its strength.
But coaching a long-running personal goal is a structure problem more than an intelligence problem. ChatGPT will happily talk you through your goal — and then forget the conversation when you close the tab. Tomorrow morning you have to set the context again. Week six you've stopped opening the chat.
MislyAI runs the same underlying intelligence (Anthropic Claude under the hood) on TOP of a goal-shaped structure: intake captures the goal, the plan persists, the morning brief reads your past week's data, the weekly recap closes the loop. Chat is one of several surfaces — useful when you need it, but not how the product knows what you're doing.
