ContextTab — research provenance graph

Turns a tab session into a branching research map: automatic lineage, inline notes, branch freezing, 1-click Markdown export.

Your tabs are a jungle. ContextTab is the map. You open a tab for research, another for a recipe, another for that thing you swear you’ll read later. Before you know it, you’re lost in 47 open tabs. ContextTab turns that chaos into a calm, visual tree—so you always know where you are, what you saved, and why you opened it. Plus, you can attach notes and highlights directly to any page. No more “Where did I read that?” Everything stays 100% on your device. No accounts, no cloud, no tracking. Just your thoughts, organized. Three reasons people love ContextTab 1. Tame tab overload – Group tabs into a clean tree that matches your thinking, not the browser’s. 2. Remember why you opened it – Add a note or highlight to any tab; your context stays with the page. 3. Private by design – Your browsing, notes, and highlights never leave your computer. It’s your brain, not a data mine. Open 50 tabs and still know exactly where everything is. ContextTab turns tab chaos into clarity—privately.
