Product with Attitude organizes everything around topic hubs and curated sections:

• Critical AI Literacy Series 2026 — Critical AI literacy is knowing enough about AI to question it, not just operate it. Plain AI literacy means knowing how to use AI tools. It means learning to prompt, create automations, and bring AI into your workflows. Critical AI literacy goes further. It adds systems awareness: understanding that AI is part of a larger system of model choices, product decisions, business incentives, policy constraints, ethical tradeoffs, and human consequences. Attitude is the posture that turns AI literacy into critical AI literacy.

• Building agents — A beginner-friendly visual guide to building your first AI agent in Claude Code, based on questions from my readers.
• Vibe Coding Hub — Vibecoding and speccoding tutorials, prompt packs, and resources
