Show HN: PromptForge – A minimal AI SaaS to generate better GPT prompts

Hi HN,

I built PromptForge – a lightweight SaaS tool designed for developers and technical teams who want to generate optimized GPT-4 prompts with minimal friction.

The core idea is: instead of writing prompts manually every time, you select a use case, fill in a few structured fields, and instantly receive a high-quality prompt ready for ChatGPT or API usage.

Features: Structured input → prompt output

Select your use case and model

Save and manage prompt history

Works with OpenAI GPT-4o via API

Clean UI, built with Lovable + Supabase

I’ve seen prompt engineering get bloated and inconsistent in teams – PromptForge aims to simplify and standardize the process, especially for recurring tasks or internal tooling.

The app is currently live and open to try: https://forge-ai-interface.lovable.app/

I’d love your thoughts and feedback, especially on:

UX (is it fast & intuitive enough?)

Dev team use cases you'd expect

Any features that seem missing or overkill

Thanks for checking it out! – Fabian
