Essevin Docs
Start with one of two paths: connect Codex or Claude Code with an API key, or create product images directly in Creative Studio.
Choose one path
You only need an API key when connecting a development tool. To make product images, open Creative Studio directly; no terminal or API setup is required.
Use Codex or Claude Code
Create a key, import it into CC Switch, and enable the Essevin provider.
Create product images
Use Creative Studio to choose a model, aspect ratio, and resolution.
