How it works

From idea to automation in minutes.

01

Create your prompt

Write your prompt, add {{variables}} for dynamic values, and organize it with categories, tags, and projects.

02

Iterate with version control

Every edit is a new version. Browse the full history, preview any past version, and revert to it in one click.

03

Run and automate

Test live against any LLM, or expose it via a scoped API key to n8n, Make, or any HTTP-capable tool.
