Chromeウェブストアより

Prompt Builder. The Ultimate AI Prompt Management Tool. Generate, optimize, test, and manage AI prompts in one place. Generate and optimize AI prompts on ChatGPT, Claude, Gemini and more. Craft Perfect Prompt in Seconds.

---

Prompt Builder puts a prompt engineer right in your browser. Open it on any AI chat site and turn a rough idea into a clear, model-ready prompt in seconds, or clean up the prompt you already typed without ever leaving the page. It lives where you already work, so you stop rewriting the same request five times and start getting better answers on the first try.

Most people lose time guessing what each model wants and copying prompts back and forth between tabs and notes. Prompt Builder closes that loop. It generates a structured prompt from your goal, optimizes the prompt sitting in your composer, tunes the wording for the model you are using, and saves the prompts that work so you can reuse them anywhere.

WHAT YOU CAN DO

Generate from a goal: describe what you want, pick a prompt type and a

target model, and get a structured, ready-to-use prompt streamed back in seconds. Edit it, improve it with a quick question wizard, or get follow-up prompt suggestions.

Optimize a prompt in place: a small Optimize button appears over the

composer once you have started typing on a supported site. One click rewrites and sharpens your prompt without breaking your flow.

Tuned for your model: Prompt Builder preselects the model that matches

the site you are on, so a prompt built on ChatGPT reads differently than one built for Claude or Gemini. Better fit means fewer retries.

Insert or copy in one click: on supported sites the finished prompt drops

straight into the chat box. Everywhere else it copies to your clipboard.

Prompt library: save the prompts that work, pin your favorites, and

reuse them across every AI tool. Search your library and your recent prompts without opening another tab.

Standing instructions: set your rules once and have them applied to every

prompt you generate or optimize, so your style and constraints carry over automatically.

Prompt types for real work: Auto, Standard, Writing, Code, Research,

Planning, Agent, Image, Video, and Automation, each shaped for the job.

Bring your context: attach files such as docs, spreadsheets, PDFs, and

code, or dictate your idea by voice instead of typing.

SEO and content: brief, draft, and refine long-form content faster.
