Hey Product Hunt! 👋 We're living in a strange moment. AI is everywhere — and it's hungry. Every tool wants your data, your files, your behavior. Upload an image here, record a screen there. It all feels convenient, until you start wondering: where does it all actually go? A few months ago, I needed to do a quick image edit before sending it to a client. I googled an online tool, uploaded my file — and halfway through I thought: wait, whose server is this sitting on right now? Is it being used to train something? That discomfort wouldn't go away. So I built LocalTools Studio. The premise is simple, almost radical in today's landscape: what if the tool never saw your file at all? Everything runs in your browser. Your image, your screen recording, your data — processed locally, gone when you close the tab. No uploads. No servers. No model training on your work. Just you and your browser. Right now there are 4 tools: 🎨 Node Image Editor — non-destructive, node-based editing with curves, masks, and compositing 🔍 Image Comparator — AI-powered diff detection with heatmap visualization 🖼️ Image Collage — combine images with flexible layouts 🎥 Screen Recorder — record straight from the browser, zero installation Free. No ads. No subscriptions. Not a launch deal — just the whole point. In a world where your data is the product, I wanted to build something where it isn't. What tool would finally let you stop uploading sensitive files to unknown servers? 👇
