When building apps with AI coding agents like Cursor, Lovable, or Bolt.new, a major issue developers face is context window decay. After 15–20 prompts, the AI starts forgetting edge cases, breaking working logic, or hallucinating data structures.
The solution is starting with a fully structured PRD and Mega-Prompt rather than vague, step-by-step instructions.
To solve this, I built TheMegaPrompt — a free, lightweight generator that turns raw app ideas into comprehensive technical blueprints.
What it generates:
Structured PRD: Core scope, feature hierarchy, and clear system boundaries.
Tech Stack & Data Schemas: Recommended stack, database schema, and API routes.
Master Mega-Prompt: A production-ready prompt optimized for AI agents to follow without context loss.
It's completely free to use with no sign-up required. Check it out at themegaprompt.com and let me know your thoughts or feedback!
