For anyone who works with AI assistants and spends too long explaining what they want. Type or dictate your idea however it comes out, and Prompt AI turns it into a complete, step-by-step prompt, ready to copy and paste. And share your projects with friends and keep them in sync, instantly.
FROM A LOOSE IDEA TO A COMPLETE BRIEF
The AI rewrites your idea as a structured brief: context, goal, steps in order, and the decisions it assumed, so you can change them. If it starts from scratch, it adds architecture, data model and requirements.
Next to the generate button you choose what the AI is an expert in: App, Web or Game.
YOUR NOTES, TIDIED UP BY THEMSELVES
When you save a note, the AI structures it: it groups what belongs together, splits it into blocks with headings and, if it's long, adds an index. Without adding or changing anything you wrote.
THE ORIGINAL IDEA IS NEVER LOST
Every prompt keeps the idea it came from: flip the card to see it, edit it and regenerate the prompt when it changes.
ORGANIZED LIKE A HOME SCREEN
• Your projects show up as icons; inside each one, two tabs: Prompts and Notes.
• Mark any project as "In production" or "Work in progress" with a touch and hold.
• Search by title or jump to a number. Copy with one tap, or share any note or prompt by link.
• Link each prompt to the notes that give it context, for free, and jump between them.
• English, Spanish and Latin American Spanish (change it in Settings). The AI writes each prompt in the language of your idea.
FREE
As many projects, prompts and notes as you want; notes are organized by the AI with no limit. AI prompts: 1 free a day and, from the second one on, each prompt (new or regenerated) asks you to watch a rewarded ad first. Sharing a project and joining one also ask for a rewarded ad. No sign-up, no email, no password.
PROMPT AI PRO
An optional one-time purchase:
• Removes the ad banner and the app-open ad.
• Unlimited prompts, with no rewarded ads.
• Lets you share projects and join other people's without ads. With a six-character code, others join and see what's written right away; each contribution shows its author, can be reported, and the owner can remove someone.
One-time payment, no subscription; the price is shown in the app before you pay.
7-day free trial: everything in Pro, only once per phone (even if you delete the app), with no charge or renewal. You need a connection to start it.
YOUR OWN AI (OPTIONAL)
Already paying for an AI? Add the API key from your Claude, ChatGPT, Gemini or OpenAI-compatible account in Settings and the app generates with it, straight from your phone. Monthly subscriptions don't work in other apps: you need an API key (Gemini's is free). The limits stay the same.
YOUR DATA
Your projects are stored on your device. Without your key, the text of your idea goes through our server to Claude (Anthropic) and isn't stored. What you share syncs through Firebase (Google) and can be deleted from Settings. The purchase is checked with RevenueCat. Anonymous usage statistics (Firebase Analytics), without the advertising identifier. When a new version is out, the app asks you to update before you keep using it.
ADS
The app shows Google AdMob ads: a banner at the bottom; now and then, when you open the app (1 in every 5 times, never on the day you install it), an app-open ad; while a prompt is generated or a note is organized, a full-screen ad (announced beforehand; at most one every 90 seconds); and, only if you ask for it, a rewarded ad to generate another prompt, share a project or join one. Before personalizing them, Google asks for your consent. "No Banner" removes the banner, the app-open ad and the rewarded ads; the full-screen ad shown while the AI works stays, also with Pro.
If you already had the subscription, you keep it (Google Play > Payments & subscriptions).
