Hi HN, I built Prompt Builder (https://www.promptbuilder.space/) because I was frustrated managing complex AI prompts in plain text boxes. The core idea: instead of one giant textarea, you compose prompts from draggable, reorderable blocks. Each block can have its own XML/custom tags, visibility toggles (so you can A/B test sections), and duplicates. Key technical details: - Live compiled preview: the right pane shows the exact string being sent, updating as you drag/toggle blocks - Dynamic variables: define {{var_name}} once, use across blocks, change in one…

Hi HN, Why I got tired of wasting time typing the same instructions to an LLM. "Proofread this," "Summarize that," "Translate this." What I built System Prompt: a free, open-source tool to create reusable AI workflows. It runs 100% in your browser, so your data and API keys stay with you. How Instead of always retyping "Proofread this text and correct it in a professional tone...", you create a reusable workflow in a 2 clicks. It's a node-based editor where you can add prompt nodes, AI nodes (for any model), and connect them. Everything is saved locally in your browser. GitHub:…

PromptForge▲10Hi HN, 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,…
