PromptiFex - Stop writing prompts from scratch. Start with the best ones.

Most AI users waste time writing the same prompts over and over. PromptiFex fixes that. A cross-platform prompt library that works across ChatGPT, Claude, Gemini, and more — with a Chrome Extension that enhances and injects prompts directly inside AI platforms. Publish prompts, share curated lists, search by provider, and collaborate in team workspaces. Available on Web, iOS, Android, and Chrome. 2,500+ organic signups. Zero paid marketing. Built solo by one founder-engineer.

We are launching PromptiFex: the project we have been building every night and weekend for the past year while working a full-time job. The problem is simple: we all use AI daily, but we write prompts from scratch every single time. We forget the good ones. We can't share them. We switch between ChatGPT, Claude, and Gemini with no way to carry our best prompts across platforms. PromptiFex solves that. It's a cross-platform prompt library with a Chrome extension that lets you enhance and inject prompts directly inside any AI platform, no copy-pasting, no tab switching. What I'm most proud of: 2,500+ signups with zero paid marketing Available on Web, iOS, Android, and Chrome Built and shipped entirely solo under my company AMDOSE LTD I'd love your feedback. What features would make this a must-have in your daily AI workflow? Thanks for checking it out
