Google Beam, formerly known as Project Starline, is an AI-powered 3D video communication platform developed by Google, designed to revolutionize remote collaboration for enterprises. Announced at Google I/O 2025, Beam transforms standard 2D video streams into immersive, lifelike 3D renderings using a six-camera array, light field display, and advanced AI volumetric video models. This technology enables natural eye contact, gesture recognition, and non-verbal cues, mimicking in-person interactions without requiring headsets. Integrated with Google Meet and Zoom, Beam offers real-time speech translation, preserving voice tone and expressions.

AI App is an all-in-one AI chatbot that offers a user-friendly interface to access several large language models (LLMs), including GPT-4, PaLM 2, Mistral 7B, and Google Gemini. It provides some key features, such as real-time web search, cross-platform compatibility, and speech-to-text conversion. Users can upload pdf documents and are able to ask questions,get summaries,and extract data.

Den, the AI-powered workspace, is a platform that integrates communication, documentation, and AI agents into a unified workspace. It emerged from Y Combinator’s Winter 2025 batch, founded by Justin Lee and Linus Talacko, to transform how knowledge workers and remote teams manage information overload and automate routine tasks. Den is positioned as an AI-native communication and documentation platform designed to replace fragmented tools like Slack and Notion, offering a seamless collaboration environment between humans and AI.
