Drop any image onto the CHITRA window (or press ⌘O). Then pick a tool from the toolbar: Enhance, Upscale, Extend, Remove, Crop, Select, Split, Score or Saliency. Hold Space at any time to compare with the original; ⌘Z undoes any step, and Edit → Revert to Original takes you all the way back.

Click the eraser tool (⌘R), then click the person or object you want gone. CHITRA outlines it instantly on your Mac; press Return and AI rebuilds the background behind it. Click elsewhere to change the target, Esc to cancel.

Pinch with two fingers to zoom up to 8×, scroll with two fingers to pan, and double-click to zoom into a point — double-click again to fit.

Each AI edit (Remove, Correct Colors, Make It Stunning, Custom Enhance) uses one credit, and a credit is only spent when the edit succeeds. Everyone gets 5 free credits every month. Need more? Buy a pack (25 for $4.99, 60 for $9.99) or subscribe to CHITRA Pro ($2.99/month) for 25 credits monthly plus 4× upscaling. Your balance is the ◆ counter in the toolbar.

All purchases are handled by Apple. Request a refund at reportaproblem.apple.com with the Apple ID you used to buy.

System Settings → your Apple ID → Subscriptions (or the App Store app → your account → Subscriptions), select CHITRA Pro and cancel. You keep the remaining credits you've already received.

• AI features need an internet connection — everything else works offline.
• Big images can take up to a minute; the spinner in the status bar shows progress.
• If the edit fails, your credit is not spent — just try again.

Click directly on the person or object — solid, clearly visible subjects work best. Very small or heavily blurred objects may not be detected.

CHITRA stores your credit balance securely in the macOS Keychain. Click "Always Allow" — this is a one-time system prompt.
