Prompt Engine
What Prompt Engine is
Prompt Engine is a web platform for creating, editing, organizing, and optimizing prompts for ChatGPT and other AI systems. Its assisted AI optimizer reviews prompts and suggests changes. Users can build multi-step prompt chains, with each step using its own content and template variables. The editor supports reusable variables that can be previewed with entered values, and prompt testing is listed as a feature.
A library organizes prompts with folders, subfolders, tags, and search, with grid and list views. Users can copy curated templates into a personal library and customize them. Prompts can be created for systems such as OpenAI, Anthropic Claude, Google, and open-source models. Personal-library prompts are private to the account, while administrators can make public templates. Users can export individual prompts or a full library. The Hobby plan is free forever and includes up to 10 prompts and 25 optimization credits. Pro costs $4.99 a month or 49 USD per year; a one-time 100-credit purchase costs 4.99 USD.
