| 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. | HeyGen is an AI video generation platform that produces talking-avatar videos from text scripts, audio, images, or documents, using lifelike avatars with accurate lip-sync and voice-synced expressions. Users can pick from a stock avatar library or create a custom digital twin from a short recording, then generate footage of the avatar speaking with synced facial movements. It also translates and dubs existing videos into 175+ languages and dialects while preserving tone and matching lip movements, and offers an API for programmatic video generation. |
