Promptly - Prompt Optimization for Vibe Coding

STOP ROLLING THE DICE WITH YOUR CODE. 🎲❌ Hi Product Hunt! 👋 This is Tiger🐯 I built Promptly because I was tired of "prompting" being a game of luck. We’ve all been there: you have a brilliant coding idea, you "vibe" it into an LLM, and it returns something totally HALLUCINATED or structurally broken. As developers, we’ve been told that prompting is the most important skill, but the truth is—LLMs are just probability machines. They GUESS. Promptly changes that. I wanted a tool where I could just ramble. I wanted to dump my messy, half-baked thoughts into a box and get back a surgical, stable, execution-ready blueprint every single time. What makes Promptly different? Unlike a simple chat interface, we built a specialized 5-step pipeline: Spec Building: We turn your "vibe" into a hard requirement. Clarifying Questions: We ask what you forgot before the AI starts. Multi-Agent Orchestration: Specialized agents (Architects, Judges) collaborate. Scoring & Metrics: We measure the result against your specific success criteria. Stability: You get the winner, not a guess. Promptly is the Stability Layer the AI era was missing. 🛡️ Stop fighting the "probability machine" and start directing. I’m here all day to answer questions, hear your feedback, and talk about the future of AI-assisted coding! 🚀 Let’s ship something stable.
