Orbiter

Orbiter — AI Tab Manager & Workspace Organizer Every power user knows the problem. You open Chrome in the morning with a plan, and by noon you have 40 tabs spread across three windows — half of them you've forgotten why you opened. Research tabs mixed with work tickets mixed with that recipe you were going to try. Context switching is brutal. Finding anything takes longer than it should. And closing tabs feels like losing something you might need later. Orbiter is built to fix exactly this. It's an AI-powered tab manager that organizes your browser into named, color-coded workspaces — and uses on-device AI to do most of the heavy lifting automatically. --- WHAT IS A WORKSPACE? A workspace in Orbiter is a named collection of tabs with a purpose. "Research — Transformers." "Work Sprint." "Home Reno Planning." "Weekend Reading." Each workspace has a color label, a live tab list, an AI-generated summary, and a save/restore state so you can put it away and bring it back exactly as you left it. Think of workspaces like virtual desktops, but for browser tabs. Switch between contexts without losing anything. Save a workspace at the end of the day and restore it tomorrow morning. Your research tabs, your work tabs, your personal tabs — all separated and organized, never getting in each other's way. --- ON-DEVICE AI CLUSTERING The most powerful feature in Orbiter is Auto Cluster. Hit the button once, and Orbiter's AI analyzes all your open tabs — their titles, URLs, and content signals — and automatically groups them into meaningful workspaces. It names them too. "Next.js Deployment," "Product Design Research," "Personal Finance," "Machine Learning Papers." This runs entirely on-device using Gemini Nano, Chrome's built-in AI model. No data is sent to any external server. No API keys. No account required. Your tabs stay private. Auto Cluster works progressively — it processes tabs in chunks and creates workspaces as it goes, so you see results appearing in real time even while it's still running. If you close the side panel mid-cluster, it keeps running in the background. Reopen the panel and the progress is right where you left it. --- PER-WORKSPACE RE-CLUSTERING Already have workspaces set up and want to refresh which tabs belong in one? Each active workspace has a re-cluster button. Tap it and Orbiter uses AI to find the best matching open tabs for that specific workspace, reassigning them automatically. The spinner persists even if you close and reopen the panel — so long background AI jobs never lose their state. --- AI WORKSPACE SUMMARIES (SNAPSHOTS) Tap the Snapshot button inside any workspace and Orbiter generates a concise summary of what that workspace is about — based on the actual content of the tabs inside it. The summary is stored with the workspace and shown every time you open it, so you always have instant context. "Comparing transformer architectures for NLP benchmarks. Attention mechanisms in BERT vs GPT variants, notes on inference latency." That's the kind of summary Orbiter produces. Useful for picking up where you left off after a long break, sharing context with a teammate, or just reminding yourself why that collection of tabs exists. Snapshots use Chrome's Summarizer API (Gemini Nano), running fully on-device. When the model isn't available yet, Orbiter gracefully falls back or hides AI features — the app remains fully usable for manual workspace management regardless of AI availability. --- BACKGROUND CLUSTER DETECTION Orbiter's service worker runs a background cluster check periodically — by default every 30 minutes, but configurable to 15 minutes, 1 hour, or off entirely. It also triggers automatically when your tab landscape changes significantly (new tabs opened, tabs closed). When the background check finds a new meaningful cluster — a group of tabs that belong together but aren't yet in a workspace — it surfaces a suggestion banner inside the panel. The banner shows the proposed workspace name and tab count, and lets you save it as a new workspace in one tap or dismiss it. This makes Orbiter feel proactive without being intrusive. --- SAVE & RESTORE WORKSPACES When you're done with a context, hit the bookmark icon on any active workspace to save it. Orbiter snapshots the full tab list — titles, URLs, favicons, last-accessed timestamps — and moves the workspace to your Saved section. The browser tabs themselves are freed up. Later, tap the restore icon to bring it back. Orbiter reopens every tab in the workspace and flips it back to active status. Your context is restored exactly as you left it. This is especially powerful for project-based work: one click to deep-focus, one click to put it away, one click to come back to it next week. --- STALE TAB DETECTION Orbiter tracks when each tab was last accessed using Chrome's native lastAccessed API. Tabs that haven't been touched beyond your configured threshold (default: 24 hours, configurable to 12h, 48h, or 7 days) are flagged as stale in the workspace detail view — dimmed visually with a red warning line separating them from your fresh tabs. The "Close Stale" button in the action bar closes all stale tabs in a workspace in one tap. This is a po…
