Live polls are a staple of conferences, streams, and all-hands: a question goes up on the big screen, everyone votes from their phone, and the bars race each other in realtime. There's a lot of different ways you could implement this.

AI adoption programs tend to end in the same place. Tools are accessible, usage is up, and there's a dedicated Slack channel for wins. Six months later, nothing about how the team works has fundamentally changed. People are doing the same things – just slightly faster. And it’s easy for programs to stall when you’re measuring the wrong thing. Adoption (whether people have access and whether they're using the tools) is visible and easy to report.

You add a stop button to your AI chat app: a customer support agent, a coding assistant, a research tool the user can steer mid-task. A user clicks it mid-response. The frontend stops rendering. Then you check your backend logs and realize the underlying generation is still running, and you’re still paying for every token. This is not a bug.

If you have built an AI chat feature with the Vercel AI SDK, you have used its useChat hook. You give it your messages, and it streams the reply into your UI. You may have seen our post on the custom transport we built for the Vercel AI SDK. It swaps useChat's default transport for Ably AI Transport, adding resumable streams, cross-device and multi-user sync, conversation branching, history compaction, and stop-and-approve controls.

You are planning a trip with an AI assistant on your laptop. You are chatting with the agent, and as you progress it is dropping pins on a map, building a day-by-day itinerary, adding up a budget, and streaming its reasoning as it goes. The state of your interactive session is a combination of the chat history, the synthetic UI constructed by the agent during that process, and structured state, the itinerary, arising from the decisions you each make.

Last week we introduced AI Transport v0.2.0 and made one idea the centre of the design: the session is the channel. Every input, output, and lifecycle event for an AI conversation is just a message published to an Ably channel, which is what makes a session durable, multi-party, and resumable. In v0.3.0, we added first-class support for presence and LiveObjects to AI sessions, allowing you and your agent to see who's online and update shared state in real time.

We audited our skills library a few months ago and found twelve dashboards hiding in it. Not dashboards. Skills that built dashboards. Someone needed a view of some data, asked Claude to put it together, got a long HTML page out of it, and then wrapped the whole thing in a skill so others could run it again. Twelve times over, by different people, for different questions.

You've built an AI chat app on the Vercel AI SDK. It works in development. The model responds, the stream comes through, and the UI updates cleanly. Then you ship to production, and the transport layer starts showing its edges. Most of these failures are quiet: things that work in demos and break in ways that are hard to pin down until you know where to look. They share a common cause: DefaultChatTransport is built for HTTP, and HTTP has structural properties that some production requirements exceed.

I ran a webinar on this recently and had more to say than the time allowed, so this is the written version: the argument I was making, some context on the demo, and the questions that came up from people watching. The recording is below if you'd rather watch than read. The thesis: AI products are being let down by the user experience, not the model.

Version v0.2.0 of @ably/ai-transport reorganises the SDK to better support a wide range of interaction patterns. Everything in an AI session – input, output, agent lifecycle, control signals – is captured durably, allowing you to easily build the sophisticated interaction patterns that support modern AI user experiences. When we first built @ably/ai-transport, we modelled an AI conversation the way most people first picture it: as a request and a response.

Most teams building agents with Temporal have solved the backend problem: crashed workflows restart, LLM call failures retry automatically, and long-running tasks complete reliably. What they haven't solved is the client side -- what happens to the stream when the user's connection drops, when they switch devices, or when two sub-agents are working concurrently and the client needs a single coherent view.

AI products today are being let down not by the models — but by the delivery layer between the agent and the user. In this session, Fiona Corden, Technical Product Manager, at Ably, breaks down why AI UX is eroding consumer trust, how to spot the delivery-layer problems hiding in your product data, and what the companies getting it right are doing differently. You'll come away knowing how to diagnose whether your AI product has a session layer problem, what durable sessions are, and why they're becoming the standard solution for resilient AI UX at scale.

How do you deliver token streams, sync conversation state across devices, and let users interrupt an agent mid-response -- without rebuilding your stack every time you switch frameworks? Mike Christensen demonstrates Ably AI Transport in action, walking through the key primitives every production AI application needs and showcasing a multi-agent holiday planning app built on those primitives. Topics covered.

React Server Components (RSCs) seem to be everywhere lately, but what problem do they really solve? In this video, Alex Booker from Ably (@CodeCast) explores RSCs from scratch, revealing the motivation and benefits behind them. You might be surprised to learn - they're not merely a React feature, but a fundamentally new model for building full-stack React applications with meta frameworks like Next 13.4 by Vercel.

Tom Camp, DevRel Engineer at Ably takes you through a tutorial of adding an avatar stack to your application using Ably's latest product, Spaces. An avatar stack is a visual representation of a user’s presence - showing them as online and connected. They are the most common way of showing the online status of members in an application by displaying an avatar for each member. Events are emitted whenever a member enters or leaves a space, or updates their profile data.

Online gamers have the most demanding realtime expectations. Mobile gaming now the largest sector of app store purchases, accounting for 42% of a $109 billion marketplace. It's vital that game developers offer a level of mobile performance that delivers an optimum realtime experience for every user. This white paper highlights some of the UX issues that can undermine your company's ability to do this effectively.

I watch sports for a living. I couldn't tell you the last time I watched a baseball game from beginning to end. Data is one of the most valuable resources around. But data is no longer something that languishes in a database to be looked at later. Like sports events, data is now live. The sports industry can reap and build on innovations in the realtime data space. But this is no long a nice-to-have. Driven by changing fan behaviour this is now a commercial imperative.

Sports and gaming app users demand an uninterrupted, true realtime experience. Almost 90% of US adults now use a mobile device while watching sports. In competitive arenas with similar offerings, like betting or sports, then you absolutely cannot afford to deliver poor mobile experiences. Customer experience is the new competitive battleground and realtime mobile experiences are an essential part of that.
