IrukaDark does not use your data for training.

Is it free to use?

Yes. IrukaDark is free to use. Install it via the Downloads page anytime.

What are credits?

Credits are the usage units for IrukaDark's AI features. Each AI operation (text explanations, image generation, AI Meeting Notes, etc.) consumes credits.

What happens when I run out of credits?

AI features become temporarily unavailable. Credits are automatically replenished each month, or you can upgrade to a higher plan for more credits.

Can I change or cancel my plan?

Yes, you can change or cancel your plan at any time. Upgrades take effect immediately, while downgrades apply at the next billing cycle.

What's the difference between Team and individual plans?

Individual plans (Free / Plus / Max) are for personal use. The Team plan adds cloud-shared AI Meeting Notes, account management, and usage analytics, ideal for collaborative work.

There are so many features -- where should I start?

Start with Option+S for screenshot explanations -- just select an area and experience AI instantly. Next, try selecting text and pressing Option+A. Then explore the clipboard feature for seamless copy-paste workflows.

Is the initial setup difficult?

It might take a little effort. You may get stuck on the Screen Recording or Accessibility permission settings. But if everything goes smoothly, it takes less than 3 minutes -- just push through the initial setup! View the Installation Guide →
