────────────────────────────── WHY YOUR AI PROMPTS KEEP FAILING ──────────────────────────────
LLM's don't fail because they're bad. They fail because your prompt is missing critical context — the right role, audience, format, tone, and constraints.
Flux fixes this automatically. It analyses your raw prompt, identifies what's missing, asks you the right questions, and builds a complete, structured prompt that gets you the exact output you wanted — first try.
