A2UI 1.0: Build delightful, fast, reliable, agentic experiences A2UI 1.0, the first stable version of an open protocol for generative UI that lets AI agents respond with interactive screens instead of text, was released with open-source renderer SDKs for web, Android and iOS and agent SDKs for Python, TypeScript and Dart. Atlassian, Alation, Bloomberg and ByteDance are already building with A2UI, which has agents describe what to show while each app renders it with its own native components at native speed. Alation Vice President of Product Management GT Volpe said "A2UI provides the interactive UI scaffolding that makes these artifacts feel like high-touch, tailored applications" in Alation or in the AI assistants customers already use. User interactions with agents today are where computers were in the terminal era: capable, and answering almost everything in text. Users can ask an agent for anything by typing or talking, and what comes back is usually a wall of text, a poor way to compare three products or edit and approve a detailed plan. Today , we're releasing A2UI 1.0, the first stable version of our open protocol for generative UI. It lets AI agents answer with interactive screens, such as a form to confirm or a chart. Developers can use it now with open-source renderer SDKs for the web, Android, and iOS and agent SDKs for Python, TypeScript, and Dart. Companies such as Atlassian https://www.atlassian.com/ , Alation https://www.alation.com/ , Bloomberg https://www.bloomberg.com/ , and ByteDance https://www.bytedance.com/ are already building with it. With A2UI, the agent describes what to show, and every app draws the UI with its own native components. The application receives A2UI messages and each app renders the content securely and at native speed. Users get the same low latency, high trust, and complete native fidelity whether they reach a company's agent in its own app or in a third-party AI assistant that hosts MCP apps, such as Gemini or Claude. You wake up sick. Getting through the morning takes six apps: book a video visit, move your meetings, tell your team, turn on an out-of-office reply, ask your partner to do school pickup and order soup. Ask a text-only agent instead, and you get a numbered wall of text, then round after round of “which ones?”. A2UI won't handle your sick day, but it gives developers the framework to build an agent that can. That agent could answer with one view of all six apps. Changing your plan is a couple of taps instead of another round of messages, and nothing is sent until you confirm. The same agent output works on any screen. Ask an agent to “move dinner with Priya to Friday”, and it can answer with one view that lines up your calendar, open tables from a restaurant booking app and prices from a rideshare app, so the time that works for everyone is obvious. The developer builds that view once with A2UI, and it renders natively on your phone and on your laptop. In both examples, A2UI is the framework that simplifies building these experiences across platforms. Developers build the agent and choose the platforms it works with. A2UI gives them the protocol the agent uses to describe each view, a way to combine components from different apps in one view, and renderers that draw it natively on the web, Android, and iOS. New to A2UI? Start with the A2UI Playground by CopilotKit https://go.copilotkit.ai/a2ui-playground or check out industry examples https://a2ui.org/get-help/ . Atlassian is bringing A2UI to Jira, where teams can assign work items to AI agents https://www.atlassian.com/software/jira/dev . When an agent needs a follow-up from the team to finish a work item, such as a missing detail or a decision, it asks with an interactive card in the work item, and the team answers right there in Jira. The Alation Intelligence Operating System AIOS builds its feeds using A2UI: metric cards, charts, and more. Each chart can show the SQL query and data behind it. Ask Claude for a feed about profitable products, and the feed renders in the conversation using A2UI to render metric cards, charts, and custom components. The same feed with the same information can be viewed directly inside Alation with a nearly identical layout.
