Developer dumaysacha argues that the moat for any new AI assistant is "100% their vibe" — personality is the hardest thing to reproduce and defines your startup's identity. He caricatures the field: ChatGPT is "your best friend, your shoulder, your bias," Claude is "your challenger with its own truth," and positions his own upcoming assistant instinct as "the only AI assistant that feels human."
The takeaway: as model capabilities converge, AI product differentiation is shifting to psychology-driven persona design.
