Hey Product Hunt! 🚀 I’m thrilled to introduce Prompt Builder, an open-source macOS app designed to simplify the process of creating long, multi-file prompts for AI models. If you’ve ever tried to feed your LLM a stack of PDFs, snippets of code, or random web transcripts, you know how cumbersome it can get. With Prompt Builder, we aim to cut through the chaos by giving you an ergonomic, all-in-one solution to gather, manage, and summarize your content before sending it off to OpenAI, Anthropic, or whichever model you prefer. Here’s what makes Prompt Builder stand out: 🔗 Local File Integration: Drag-and-drop your docs, markdown files, or even images right into your prompt blocks. No more losing track of references! ⚡ Summaries on the Fly: Long text? Hit “Summarize” to condense your content before injecting it into the prompt. Keep your token usage tight and efficient. 🧮 Token Insights: Quickly see estimated token counts so you don’t exceed model limits—or your own budget. 🛠️ Dynamic Prompt Blocks: Reorder, collapse, or expand blocks of text with ease. Build your prompt step by step and visualize the final context in one place. 🌐 YouTube & Web Transcripts: Paste a link, let Prompt Builder fetch the transcript, then either inject it directly or shorten it with a quick summary. 📚 Snippets Library: Save reusable prompts or instructions, then drop them in as building blocks any time. We’re in alpha (v0.0.2), so expect rapid improvements and a few quirks. I’d love your feedback on what features to tackle next—whether it’s Windows support, new summarization options, or more integrations. If you’re excited about making AI workflows more efficient, give Prompt Builder a try and let me know what you think. Happy building, and see you in the comments! 🙌
