Start a conversation on your laptop, finish it on your phone. The context just follows you. That’s what cross-device AI sync delivers. No reloading history, no reintroducing yourself, just one continuous thread across every screen. It builds trust, reduces friction, and makes the assistant feel like a single, persistent presence. This post unpacks why users expect it, what makes it technically tricky, and what your system needs to get it right.

Refresh the page, lose signal, switch tabs - the AI conversation just keeps going. That’s what reliable, resumable token streaming makes possible. No restarts, no lost context, just the same response picking up right where it left off. It keeps users in flow and builds trust, making conversations feel seamless. Even better, it unlocks things like switching devices mid-stream without missing a beat.

Ably AI Transport is now in early access. It gives your AI the continuity, awareness, and multi-device reliability users actually expect. Drop it in, keep your existing stack, and start shipping Gen-2 AI right away.
