Prompto rewrites your prompt into a clear, effective one — the instant before it reaches the AI. A better answer the first time, no prompt engineering required.
No new tab, no copy-paste, no prompt library to manage. Prompto lives where you already type.
Write your rough prompt in ChatGPT, Claude, Gemini, or Perplexity — however messy it is.
Prompto rewrites it inline in about a second — clearer instructions, structure, and intent.
Get a sharper answer the first time, instead of three rounds of "no, I meant…".
One extension across every major model — plus a desktop app that works in any app, even your terminal.
Developers, marketers, founders, writers, students — anyone who sends dozens of prompts a day and wants every one to land.
Clearer prompts get better answers. Prompto applies the structure good prompt engineers use — so you never have to learn the tricks.
Everything you need, nothing in your way.
It clarifies and structures your intent — it never invents facts or puts words in your mouth.
General, concise, detailed, coding, or creative. Pick how Prompto rewrites with one click.
Fast enough that hitting the hotkey before you send becomes pure muscle memory.
See and edit the optimized prompt before it sends — or flip on instant mode for one-press send.
Only the prompt you choose to optimize is sent. No conversations, no tracking, no ads.
The extension for AI sites, the desktop app for everything else — one account unlocks both.
Start free — no account, no card. Go Pro when you want unlimited.
