Fast, Private
Tab & Workspace Manager
Organize tabs into fast, private workspaces with focused dashboard widgets and offline notes. Synthesize your tabs, log your achievements with device-native AI, and navigate history with chronological Time Travel snapshots.
The Four Pillars of Focus
Ditch the chaos of infinite tabs. loci partitions your work into structured, intelligent layers.
Context-Isolated Workspaces
Segregate your tabs, resources, and notes by project. Switching spaces auto-marshals your browser state instantly, restoring only what you need and saving memory by suspending inactive sessions.
- 📁 4-Level Nested Subspaces for deep project organization.
- 🔄 Chrome Tab Group integration for visual partitioning.
- 🧹 Duplicate tab cleaner to close redundant URLs in one click.

Interactive Focus Dashboards
Replaces your blank new tab page with a customizable high-end workstation. Drag, drop, and resize widgets to build a layout that serves your exact workflow.
- 📝 Rich Text Notepad utilizing TipTap with markdown shortcuts.
- 🎯 Primary Daily Focus and Todo checklists to prioritize work.
- ⛅ Auto-refreshing widgets for stocks, weather, and bookmarks.
My Daily Target
"Finalize the production build pipeline & deploy landing page"
Zero-Leaks AI Smart Cleanup & Clustering
Declutter your browser automatically. Runs local text embeddings via Transformers.js (WASM/WebGPU) and Chrome Gemini Nano in an offscreen document to measure tab cohesion and cluster duplicate spaces.
- 🧹 Surfing Session Detection: Flags low-cohesion random browsing spaces (<22% similarity).
- 🔀 Semantic Workspace Clustering: Identifies duplicate workspace pairs (≥75% similarity) for one-click merging.
- ✨ Chrome Built-in AI: Hardware-accelerated Gemini Nano Prompt API support.
AI Cleanup Advisor Recommendation
"Merge duplicate spaces 'Product Launch' and 'Vite Build Setup' (78% semantic similarity detected)."
Time Travel Timeline History
Never lose your session state. loci tracks incremental changes using a custom delta-logging engine, letting you rewind your workspace to any past state or restore individual closed tabs.
- 🕒 Chronological history drawer logging full baselines and deltas.
- 💾 Storage efficient diff-logging to stay under browser quotas.
- 📤 Manual JSON backups to export and import spaces offline.

The Local-First Manifesto
Unlike other workspace managers that upload your browsing history, tab titles, and active logs to their databases, loci is zero-leak by default.
Our AI Logger performs summarization and generates text embeddings directly inside your browser using hardware-accelerated WebGPU and WASM runtimes. No cloud calls, no data mining, and absolutely no training on your data. Your thoughts remain yours.
