Show HN: I made PromptForge – Generate perfect GPT prompts from structured input
forge-ai-interface.lovable.app
I recently built PromptForge — a minimal, developer-first web app that helps you generate high-quality GPT prompts from just a few structured fields.
Why? As a developer, I often found myself rewriting similar prompts manually. I wanted a faster and more reliable way to generate optimized prompts for various tasks — coding, debugging, idea generation, etc. So I built a tool that combines structure, speed, and simplicity.
What it does: Select a use case (e.g. summarization, code explanation)
Fill out a few fields (context, tone, output format)
Get a clean, optimized prompt
Save, reuse, and iterate with prompt history
Fully responsive UI + API-ready output
Tech Stack: Frontend: Lovable
Backend/Auth: Supabase
AI: OpenAI GPT-4o (via API)
The app is currently in public beta. You can try it here: https://forge-ai-interface.lovable.app/
Would love your feedback on:
Prompt generation quality
UI and workflow for devs
Features you'd expect in an AI prompt builder
Happy to answer any questions!
