| 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. | Bolna is an open-source platform for building, testing, and deploying AI voice agents that hold natural phone conversations, handling pauses and interruptions across inbound and outbound calls. The agents answer calls around the clock, book appointments, qualify leads, screen candidates, and provide customer support, with call transcripts and performance analytics. It orchestrates speech-to-text, LLM, and text-to-speech providers over telephony services like Twilio and Plivo, supports 40+ languages including Indian vernaculars, and can run at scale via hosted APIs or self-hosting. |
