# Lastbrowser

> Lastbrowser is the AI-native Windows browser built with Chromium and an in-tree local Python Sidekick engine. It features an integrated AI Copilot (Nova AI), 48 built-in agentic workflows, vertical Zen sidebar, Spaces with complete session partition isolation, a native ConPTY PowerShell terminal, and full Castlabs Electron Widevine DRM L3 support for protected media streaming.

## Core Pillars
- **Platform:** Windows 10 & 11 (x64) native desktop application.
- **Privacy & Security:** 100% Local-First. Zero telemetry. All tabs, cookies, and keys stored in `%APPDATA%\Lastbrowser` with Windows DPAPI encryption.
- **AI Integration:** Configure available AI providers in the app settings or use local Ollama models. Provider availability and costs depend on the service.
- **Spaces:** Strict session isolation (`persist:profile:space`) separating cookies, cache, and logins per Space.
- **ConPTY Terminal:** Native Windows pseudo-console embedded in the browser sidebar.
- **Commercial Licensing:** Free for personal use, research, and open source. Enterprise rollout and commercial fleet deployment contact: `rainer@dominik.in`.
