Hello Product Hunt community! I’m thrilled to introduce Katalyst to the world today! This project was born out of my own frustration with browser clutter. Like many of you, my daily workflow involved switching between 5 different tabs just to access different AI models, opening separate extensions for text summaries or translations, and using a completely different app for my Pomodoro timer. It was a massive focus killer. So, I built Katalyst: a single, premium sidebar that centralizes everything you need to read, process, and create faster on the web, without ever leaving your active tab. Here is what’s packed inside the sidebar: - Your AI Companion : Ask anything and get instant answers from ChatGPT, Claude, Gemini, Perplexity, or Mistral with full page-context integration. - Instant Summaries : Generate one-click clean Markdown summaries of any length. - Seamless Translation : Break language barriers instantly on any webpage. - Built-in Power Tools : A focus-driven Pomodoro timer, a pixel-accurate color picker, and quick page citations. We designed Katalyst with a premium, distraction-free "Deep Forest" dark aesthetic because productivity tools should look as good as they perform. Katalyst is available right now with a generous Free Plan and a Pro Unlock at just €8/month for power users who want unlimited AI access. I’m hanging out in the comments all day and I’d absolutely love to hear your thoughts, feedback, and feature requests. What should we add next to the sidebar? Thank you so much for your support!
