Install ChatGPT plugin
Knock is a plugin in ChatGPT and Codex. Prompt either one to build and manage workflows, broadcasts, guides, templates, and audiences.
The plugin includes skills for engagement work such as win-back, onboarding, growth, and improving the messaging you send. It runs on the Knock MCP server and can use the Knock agent. You do not need a local setup or a service token. Sign in with an existing Knock account, or create one during install.
In Codex, you can stay in the agent you use to write product code while you build the email and in-app messaging that ships with it.
