The App

Everything you need to
forge a legend.

HeroForge is a native macOS app built around one idea: giving everyone the ability to create a superhero that's truly their own — no prompting expertise needed.

🎨

Full creative control

Name, gender, build, powers, costume style, colors, cape, mask, mood, setting, art style — every detail is yours to set.

⚡

One click randomize

No inspiration? Hit Randomize and get a fully configured hero in a split second. Regenerate as many times as you like.

🌍

Italiano & English

Switch language in the toolbar. The entire UI — and the generated prompt — adapts instantly to English or Italian.

📚

Persistent history

Every hero you generate is saved automatically. Revisit past creations, copy their prompt, or export them as PNG anytime.

🔒

Your key, your data

HeroForge uses your own OpenAI API key, stored locally in macOS preferences. No accounts, no subscriptions, no tracking.

💸

Pay only what you use

DALL-E 3 HD costs ~$0.08 per image. HeroForge itself is free. You're in full control of your spend.
