| Description | Perplexity AI is a conversational answer engine that searches the web in real-time and provides cited, accurate answers. Used by 10+ million users who need research-grade answers without the noise of a traditional search engine. | 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. |
