About Kortex: All-in-One AI Browser Assistant

KORTEX — YOUR BROWSER IS A MESS. FIX IT. Let’s be honest. You’ve got 40+ tabs open, you’re only using three of them, and the rest are just eating your RAM and giving you anxiety. Kortex is a clean, lightweight sidebar that helps you organize tab chaos without overthinking it. WHAT IT ACTUALLY DOES • One-Click Clean Up Group all those “research” tabs into a single workspace. Your tab bar clears instantly, but everything stays one click away when you need it again. • Total Privacy No accounts. No “Sign in with Google”. No trackers. Your data stays on your device — always. • Zero Subscriptions Most tools charge monthly just to save links. Kortex is free to use. Save as much as you want without the attention tax. • Built-in RAM Check See exactly how much memory your open tabs are consuming before you archive them. THE FUN STUFF • AI Agents (Coming Soon) We’re building AI agents to handle the boring work — summarizing saved tabs, organizing notes, and more. You can join the waitlist inside the app. STOP HOARDING TABS. START ACTUALLY WORKING. Install Kortex, clear your head, and get back to what matters.
