Session video

A durably-stored recording of a browser run, plus real-time live view — so every automated session is watchable and auditable after the fact.

What is session video?

Session video is a recorded capture of a browser run, stored durably and viewable after the session ends, alongside a real-time live view while it executes. It turns an otherwise opaque automated run into something a human can watch step by step.

Why it matters

When automation acts on authenticated, consequential workflows, “it ran” isn’t enough — you need to see what it did. Durable session video supports debugging, audit, and the human-in-the-loop handoff, and is part of why Twin fits regulated and internal-ops use cases.

Run your first skill

Give an LLM agent a real browser, compile the workflow once, and watch the marginal cost fall as the cache takes over.
