PROMPTDEX

Optimize and sharpen your AI prompts right in the chat page — one click, no tab switching, no copy-paste.

Write your prompt once and make it dramatically better — without switching tabs or copy-pasting. PROMPTDEX sits inside the AI chat page you already use. One click turns a rough prompt into a structured one that actually gets you the answer you wanted. BRING YOUR OWN API KEY (BYOK) We do not resell tokens and we run no server that touches your prompts. You use your own API key, and requests go straight from your browser to the AI provider you chose. No middleman, no monthly fee from us, no quota we could ever switch off. FOUR IMPROVEMENT MODES • Improve — make the prompt clearer and more focused • Enhance — add detail, structure, and context • Refine — sharpen it to be more precise and specific • Shorten — condense it without losing the point PROMPTS THAT MATCH THEIR DESTINATION Pick one of 29 destination tools and the shape of the prompt changes with it. Some image tools want comma-separated tags and an aspect-ratio marker at the end; others want negatives on their own line. Music tools want a style line plus lyrics with section markers. Coding tools want a technical brief that says how to verify the result. One prompt pasted everywhere never really fits — now it doesn't have to. FIVE MODALITIES Text, image, video, audio, and code. WHAT YOU CAN DO • 151 ready-made skills for writing, SEO, marketing, research, and analysis — plus build your own or import from .md/.txt files • 112 prompt templates across 11 categories, plus 112 image and video prompts • Fill prompts in like a form — templates are full of blanks, and one button lifts them all into a list of fields with a live preview • Command palette — press Cmd+K or Ctrl+K anywhere to reach every page, tool, skill, and built-in prompt from one search box • Prompt Chain — link up to 8 steps, where each step's output becomes the next step's context • A 1–10 prompt quality score before and after, with suggestions • Mark what actually worked — rate a result after you have seen the AI's answer, and the stats tell you which kinds of prompts really work for you • Global Variables — write {{brand_name}} once and it fills itself in on any prompt • Structured Brand Profile — save your audience, tone, and the things your brand never says, then reuse them anywhere • Chat Handoff — a long conversation in one AI service is condensed into context and dropped straight into another service's composer • Keyword shortcuts — type ;bio then Tab and your shortcut expands into the longer text, on any website • Save text from the web — select text on any page, save it to your library or turn it into a shortcut • Share a prompt as a link — the content lives inside the link itself, stored on no server • Video to Prompt — open a video, get a prompt that would produce something like it • A private library with folders, favourites, search, and context snippets • Versioned history — compare revisions of the same prompt • Batch Runner — one instruction across dozens of inputs at once • Screenshot to Prompt — grab an area of the screen and turn it into text, context, or a prompt • Voice to Prompt — dictate straight into the prompt box • Rewrite an article from the current page, a URL, or text you paste • Ask This Page — ask anything about the page you have open • Summarize a video from its transcript • Image to Prompt — upload an image, get a prompt that could produce something like it • Localizer — one text rewritten naturally into several languages at once • Aspect-ratio control for image and video prompts: 1:1, 4:5, 9:16, 16:9, 4:3, 3:2, 21:9 • Quick Actions on any site — select text, then optimize, improve, summarize, or translate it • Token and cost estimates before a prompt is sent THE MODEL LIST COMES FROM YOUR OWN PROVIDER Model names are read live from whichever provider your API key belongs to, so newly released models show up without waiting for us to ship an update — and retired ones stop being offered. You can also type any model name yourself. THREE WAYS TO OPEN IT A popup, a side panel, or a full tab with a sidebar. You choose in Settings. PRIVACY BY DEFAULT • A Privacy Shield checks your prompt for sensitive data — email addresses, phone numbers, national ID and tax numbers, card numbers, API keys — before it is sent. The whole check runs inside your browser. • Your API key is kept in your browser's local storage and is only ever sent to the AI provider you chose yourself. • We collect nothing about you and sell nothing about you. SYNC ACROSS DEVICES WITH NO SERVER Your library, history, templates, and settings can sync through your own Chrome account. There is no extra account to create. A BILINGUAL INTERFACE English and Indonesian, switchable any time. The interface language is separate from the output language — you can read English menus and still get answers in another language. PAY ONCE One licence, yours to keep. Not a subscription.
