Project Astra
Also known as: Google Project Astra, Astra
Project Astra is Google's name for the research program exploring what a persistent, multimodal, real-time AI assistant could look like. Think of it as Gemini's more ambient, context-aware sibling: you point your camera at something, ask a question, and Astra draws on both what it sees and what it remembers from prior conversations to respond naturally.
At I/O 2025, Google showed Astra capabilities including improved memory (so the assistant remembers things you showed it earlier), native audio for more natural voice output, and computer control for navigating interfaces on your behalf. The capabilities are being gradually rolled out into Gemini Live and Google Search.
For builders, Astra is a research signal more than a product you can ship today. It defines the direction Google sees for ambient AI, where the assistant is always present, multimodal, and persistent, rather than something you consciously invoke. The Live API for developers exposes some Astra capabilities for building real-time multimodal applications.
