Sierra Releases Ghostwriter, an Agent That Builds Customer Service Agents
Bret Taylor announces that Sierra is releasing Ghostwriter, which lets enterprises create customer experience AI agents through conversation rather than forms, with voice, multilingual support, system actions and guardrails. He argues every software UI will eventually be an agent.

Codex and Claude Code have transformed how we build software, making it possible for software engineers to orchestrate and review the work rather than doing all the work themselves. We think the same transformation will happen for all software. Rather than every enterprise app having a web app for humans and an API for automation, every software platform’s UI will be an agent that can do the work on your behalf.
I recorded a demo of my building and optimizing an agent with Ghostwriter so you can see how powerful and easy it is to use. It’s completely changed the way our early adopters build agents, and it’s changed the way I think about the software industry. Let me know what you think, and, if you’re interested in trying it out at your business, please reach out directly.
