Momentum OS - Tab Session Manager

Momentum OS — A work OS for Chrome You don’t need another tab manager. You need to get back into flow. Momentum turns Chrome into a live workspace. It watches how you actually work — which tabs you dwell on, revisit, and group — and organizes that chaos into sessions you can resume in seconds. No new habits. No content scripts. No reading your browsing history. Your work, in motion Open the side panel and see what you’re really working on: active sessions, open tabs, focus time, and what still needs attention. A calm command center that stays open while you browse — not a popup you forget exists. Sessions that detect themselves Momentum clusters related tabs into work sessions using domain affinity, dwell time, revisits, and native tab groups. Debugging auth? Comparing vendors? Planning a launch? Your tabs become named units of work — automatically. Lanes with a next step Inside every session, move tabs through clear lanes: Researching Comparing Drafting Waiting Done So “what do I do with this tab?” always has an answer. Checkpoints before context switches About to jump into a meeting, close your laptop, or start something new? Save a checkpoint — tabs, notes, and progress captured in one shot. Restore later in a fresh window or regroup into what you already have open. Pick up exactly where you left off Resume briefs tell you what you were doing, what changed, and what to do next — generated from smart heuristics out of the box. Optional AI (your key, your choice) makes them even richer. Built for speed ⌘/Ctrl + Shift + M — open the side panel ⌘/Ctrl + Shift + S — save a checkpoint ⌘/Ctrl + Shift + R — restore your last session ⌘/Ctrl + K — command palette for everything else Calm productivity. Private by default. Everything lives in chrome.storage.local on your device. Momentum does not request browsing history or host permissions. No page injection. No data leaving your machine unless you explicitly turn on the optional AI layer — and even then, you control what gets shared. Who it’s for Developers juggling docs, GitHub, and dashboards. Founders switching between research, analytics, and email. Students comparing sources across a dozen tabs. Anyone who does real work in the browser and hates rebuilding context from scratch. Not a to-do app. Not “AI summarization.” A work OS. Install Momentum. Keep browsing like normal. Come back tomorrow and know exactly where you left off.
