PromptCraft

What it does

PromptCraft is a free AI prompt engineering tool. Users sign in with email, send a rough idea in the chat, and receive a clearer prompt with relevant context, constraints, and a target output format. The site says it works with any text-based LLM and that prompts can be used commercially. Messages are sent to the backend to produce a response, and the site says it does not log message content to disk. Supported browsers are the latest two versions of Chrome, Firefox, Safari, and Edge, and mobile browsers are supported.

The home page has a chat area, a Clear button, example prompts, and an FAQ. It says conversations are saved locally in the browser. It also says an email sign-in is required to use the chat. The FAQ states that each message is sent to the backend to produce a response, and that the content of messages is not logged to disk. It says the output is a plain-text prompt that can be pasted into any chat box. It lists support for the latest two versions of Chrome, Firefox, Safari, and Edge, plus mobile browsers. The page has links to Blog, Report an Issue, Privacy Policy, and Terms of Service. The FAQ says PromptCraft is free and that users own the prompts they create and may use them for lawful purposes, including commercial work.
