Prompt Engineer
Add to Chrome
A Chrome extension for anyone who types online

Write the prompt you meant to write.

Prompt Engineer lives inside every text box on the web. Turn a rough idea into a detailed AI prompt, fix your grammar, translate on the fly, or reach for one of eight writing tools — without ever leaving the page.

Why it's different

Not another AI tab to juggle.

Prompt Engineer doesn't ask you to copy, paste, and switch windows. It works right where your cursor already is.

Enhance any prompt

Type a rough idea into any AI chatbot, form, or comment box. One click turns it into a clear, detailed prompt that gets better answers.

Nine tools, one click away

Translate, fix grammar, rewrite for tone, summarize, humanize AI text, and more — a shortcut away from wherever you're typing.

Shortcuts that stay out of Chrome's way

Every shortcut runs on Alt+Shift, so nothing collides with your browser's own commands. One page lists them all.

The tools panel

One panel. Nine jobs.

Open the toolbar over any text field and reach for exactly the tool the moment calls for. Try one below.

How it works

Three steps. No copy-paste.

1

Type

Write anything, anywhere — a comment box, an email, a chat window, a form.

2

Trigger

Click the floating icon that appears over the field, or press a keyboard shortcut.

3

Get your result

The text updates right there in the field. Nothing to copy, nothing to paste.

Built for your keyboard

Every tool, one shortcut away.

Every combination uses Alt+Shift, so it never fights with Chrome's own shortcuts. A dedicated page inside the extension lists every one.

Questions

Good to know

What's included in the free plan?

Three AI prompt enhancements a day using our built-in template engine — enough to try the extension before you commit to a plan.

Do paid plans use real AI?

Yes. Pro, Premium, and Ultimate call the Google Gemini API through our secure server to generate tailored prompts and tool output. You never need your own API key.

Does it work on every website?

Anywhere you can type — Gmail, LinkedIn, X, Notion, forms, and chat apps all work the same way.

Is my text sent anywhere?

Free tools run locally in your browser. Paid tools send your text to Gemini through our server to generate a result. We don't sell your data — see our full Privacy Policy for details.

Write like you mean it.

Add Prompt Engineer to Chrome and turn your next rough draft into the version you actually wanted to send.
