Today, Sierra is releasing Ghostwriter, our agent for building agents. With Ghostwriter, you can create an AI agent for your customer experience — one that can chat, pick up the phone, speak dozens of languages, take action on your systems of record, and be protected with industry-leading guardrails — simply by having a conversation. No clicking, no forms, no menus. 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.

Build once. Deploy everywhere. From chat to voice to email, Sierra agents adapt to every channel your customers use. 🎥 Our Product Manager, @zackrw, explains how in this quick Q&A: youtube.com/watch?v=TDmgGXbU…

Today we're excited to announce a new way to interact with Sierra agents: voice. Learn more about how this new capability is transforming customer interactions in our latest blog post.: sierra.ai/blog/sierra-speaks
