One hotkey. A better prompt.

No new tab, no copy-paste, no prompt library to manage. Prompto lives where you already type.

⌨️

Type it — or say it

Write your rough prompt anywhere — an AI chat, an email, your editor — or hold the voice hotkey and just talk. Let go, and your words land right in the box.

Hit your hotkey

Prompto rewrites it inline in about a second — clearer instructions, structure, and intent.

Send the better version

Get a sharper answer the first time, instead of three rounds of "no, I meant…".

Everywhere you talk to AI

One global hotkey that works in every app on your PC — every AI chat, plus email, docs, and even your terminal.

A sharper answer, first try.

Clearer prompts get better answers. Prompto applies the structure good prompt engineers use — so you never have to learn the tricks.

Quietly powerful

Everything you need, nothing in your way.

🎯

Your voice, sharper

It clarifies and structures your intent — it never invents facts or puts words in your mouth.

🎨

Five styles

General, concise, detailed, coding, or creative. Pick how Prompto rewrites with one click.

Under a second

Fast enough that hitting the hotkey before you send becomes pure muscle memory.

👀

Always a preview

See and edit the optimized prompt before it sends — or flip on instant mode for one-press send.

🔒

Private by default

Only the prompt you choose to optimize is sent. No conversations, no tracking, no ads.

🖥️

Works in every app

One global hotkey brings Prompto to ChatGPT, your editor, email — anywhere you type on Windows.

🎙️

Voice input built in

Hold a hotkey and talk — release, and your words are typed into the box for you. Prefer hands-free? A second hotkey toggles the mic. One more makes it all sharp.

Built for the prompts people actually send

Prompto is not a prompt library you have to search. It fixes the rough prompt already under your cursor.

Questions

Where does Prompto work?

Everywhere. Prompto's Windows desktop app gives you one global hotkey that works in any app — ChatGPT, Claude, Gemini, Perplexity, plus email, docs, and even your terminal.

Can I dictate prompts with my voice?

Yes, two ways. Hold the push-to-talk hotkey (Ctrl+Alt+Z by default), say your prompt, and let go — Prompto types your words straight into whatever text box you're in. Or go hands-free: Ctrl+Alt+A starts the mic, pressing it again stops. Then hit the optimize hotkey to sharpen your words, or turn on auto-optimize in Settings to do both in one step. Voice uses the same free daily allowance as optimizations.

Do I need to know prompt engineering?

No — that's the whole point. You type naturally, and Prompto applies the structure and clarity that good prompt engineers use, so you don't have to.

Is it free?

Yes. Prompto is free to download and gives you 10 optimizations every day with no account or card. Want unlimited? Pro is $10/month, cancel anytime.

What do I get with Pro?

Unlimited optimizations in the desktop app for $10/month — cancel whenever you like. The free tier already unlocks every style.

Windows says “unknown publisher” — is it safe?

Yes. Prompto is a brand-new indie app and isn’t code-signed yet (that’s a pricey certificate we’ll add as we grow), so Windows shows a one-time SmartScreen prompt. Click More info → Run anyway. You can confirm the download is genuine with the SHA-256 link under the download button.

Is my data private?

Prompto only reads the prompt you choose to optimize, the moment you trigger it — never your conversations or other pages. It isn't sold or used for ads. See our privacy policy.
