AIPrompter

AIPrompter is a browser extension for the part of AI image generation that people find hardest: writing the prompt. Installing it adds a helper panel to the browser that lets you build up a prompt from a large vocabulary of descriptive terms rather than typing everything from memory. It is aimed at users of Stable Diffusion, Midjourney, ComfyUI, Fooocus and Leonardo.ai, and stays out of the way of whichever generator you happen to be using.

The extension has three main capabilities. A prompt vocabulary library lets you search a broad set of terms and insert any of them into your prompt with one click, which is useful when you know the effect you want but not the exact wording. A one-click translation action converts text you type or paste, so prompts, tutorials and community ideas written in another language become directly usable. And an AI suggestion feature takes a keyword or short phrase and proposes related prompt terms to help you finish the thought.

AIPrompter is free, published as a small lightweight extension and has a modest but positive rating history on the Chrome Web Store. It is a focused utility rather than a full prompt-management suite: there are no team features, cloud libraries or paid tiers, and the interface is in Simplified Chinese, which makes it most comfortable for Chinese-speaking creators.
