Text Eraser

Why It Exists

Users want to remove unwanted text from photos without complex editing. Text Eraser provides a specialized, one-touch solution for text removal.

How It Works

Text Eraser uses on-device AI models to detect, select, and remove text elements from photos. Unlike AI Eraser which removes objects, Text Eraser specializes in removing text-based content such as watermarks, captions, and signatures. The AI reconstructs the background behind the removed text to create a seamless result.

Everyday Use Cases

• Remove a watermark from a photo
• Delete an unwanted caption
• Remove a timestamp from a screenshot
• Clean up a photo by removing text overlays

User Workflow

• Open Gallery app and select a photo
• Tap the Text Eraser button
• AI auto-detects text regions or select manually
• Confirm removal
• AI processes and generates the result
• Save the edited photo

AI Processing Flow

On-device computer vision model for text detection, followed by AI inpainting for background reconstruction.

Inputs / Outputs

Inputs:

• Photo pixels
• Text region selection or auto-detection
• Background context

Outputs:

• Edited photo with text removed
• Generated background fill

Known Limitations

• Requires HyperOS AI-enabled device
• May struggle with text on complex or transparent backgrounds

Unsupported Scenarios

• Does not work on devices without NPU
• May produce artifacts on very complex backgrounds or overlapping text

Performance Notes

On-device processing is fast for most text removal. Processing time varies by image complexity and text density.
