Journaling works. Decades of research back it up — writing your thoughts down, naming what you're feeling, and examining it on the page builds self-awareness and resilience in ways that talking alone doesn't. Therapists have known this for generations.

My sister-in-law is one of them. Over the years I watched her write out questions for her daughter to answer in a journal. Not a diary. A guided conversation with herself, designed to build the kind of self-awareness that actually changes how you see the world.

Then AI got good enough for teenagers to use it daily. Her daughter started asking an AI chatbot “am I being dramatic?” after arguments — and the AI told her what she wanted to hear. Every time.

That's the problem with validation-first AI. It's optimized to make you feel good, not to help you grow. Journaling works precisely because it doesn't let you off the hook.

One night I wrote her mom a long prompt — a framework for how an AI should respond like a good counselor would. Not with validation. With curiosity. With the one honest question you weren't asking yourself.

That prompt became the foundation of Lull.
