| Description | Project Astra is a research prototype from Google DeepMind exploring the capabilities needed for a universal AI assistant that can understand and respond to the world in real time. Built on Gemini models, it processes text, voice, images, and live video to answer questions and complete tasks, drawing on Google apps like Search, Maps, and Lens. It is currently available only to selected testers on Android phones and prototype glasses, and its features are being folded into products such as Gemini Live. | Brave Leo is an AI chat assistant integrated directly into the Brave browser on macOS, Windows, Linux, Android, and iOS, requiring no extension. It reads the content of the active tab—webpages, PDFs, Google Docs, and YouTube videos—to answer questions in context, and offers an early-access agentic mode that autonomously completes multi-step tasks in an isolated profile. It emphasizes privacy, requiring no account, keeping chat history local, and not using conversations for model training. |
