IN ONE SENTENCE
LastBrowser is a Chromium-based desktop browser for Windows and Linux that brings web pages, separate workspaces, and an AI assistant together in one interface.

DESCRIPTION
LastBrowser combines browsing with AI assistance in the context of your work. Separate Spaces organize projects and sign-ins; Sidekick helps with reading, summarizing, and working with content. AI features depend on the provider, access method, and build. Local-First distinguishes local storage from deliberately configured cloud features.
