Promptle - AI Prompt Guessing Game
Hey Indie Hackers!
I recently built Promptle, a game where you try to guess the hidden AI prompt behind an image.
You see an AI generated image and must figure out what prompt created it. The closer your guess, the more points you earn.
What is Promptle?
Promptle is a game where players try to guess the AI prompt behind an image.
You are shown an AI-generated image and must reverse engineer the prompt that created it. The closer your guess is to the original prompt, the higher your score.
It turns prompt engineering into a fun puzzle instead of a technical task.
How it works
• Look at the AI-generated image
• Guess the prompt that created it
• Get feedback on how close your guess was
• Improve your score and climb the leaderboard
Features
• Daily AI prompt puzzles
• PvP mode where players race to guess the prompt
• Leaderboards and scoring
• A fun way to explore prompt engineering
Why Promptle?
AI image generators are everywhere, but most people never see the prompts behind them.
Promptle makes that hidden layer visible by turning it into a game. It helps players understand how prompts shape AI images while having fun competing with others.
Whether you're an AI enthusiast, developer, or just curious about how prompts work, Promptle turns prompt discovery into a surprisingly addictive challenge.

Cool concept. Reverse engineering prompts is a great way to learn what actually matters in them. Most people write prompts as one big paragraph, but the ones that produce the best images (or text) tend to have clear structure. Style, subject, composition, mood, all as separate pieces.
I work on something in a similar space but for text LLMs. flompt is a visual prompt builder where you lay out 12 typed blocks (role, objective, constraints, examples, etc.) on a canvas and compile them into Claude-optimized XML. Same core idea: breaking prompts into labeled parts gives you more control than freeform text.

Love this. It just happens to be a new addiction really. PvP mode is fire 🔥
This is nice! Best of luck!
