- 📁 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.

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.
