100% offline AI prompt dashboard ⚡️ | Prompt Vault

Hey Product Hunt! 👋 I'm Faizan, the maker of Prompt Vault. I use ChatGPT and Claude daily, but I was going crazy trying to manage my "fill-in-the-blank" prompts. They were scattered across Notion, Apple Notes, and random text files. Manually hunting down and replacing [Insert Target Audience] every single time was ruining my workflow. So, I built a solution to scratch my own itch. Prompt Vault is a lightning-fast, local-first prompt engineering dashboard. ⚡️ The Killer Feature: You type {{Target_Audience}} in your template, and the vault instantly generates a clean input box for you on the side. Fill it in, hit copy, and you're done. 🔒 100% Private & Offline: I wanted this to be completely frictionless. There is no database, no backend, and no monthly subscription. It’s built entirely as a single HTML file using Tailwind CSS and Vanilla JS. It saves everything securely to your browser's LocalStorage. 💻 Zero Setup: You literally just download the folder and double-click the HTML file to open it. I've packaged the source code with a "Starter Pack" of 5 premium templates for Coding, Sales, and Marketing so you can start generating immediately. I would absolutely love to hear your thoughts on the UI and the local-first approach! I'll be here all day answering questions. 👇
