W-Agent

W-Agent is a free online tool that uses AI to clean up unwanted overlays from your videos and images. You upload a file — MP4, MOV, PNG, or other common formats — and the AI automatically detects and removes things like subtitles, logos, watermarks, and text. The tool handles videos up to two minutes long and resolutions up to 2560x2560, all without requiring any software installation or account signup.

The process is straightforward: upload your file, let the AI detect the overlay (or guide it with bounding boxes and brush masks), and download the cleaned result. For videos, you can also scope masks to specific time ranges for more precise control. The AI uses inpainting to reconstruct the background after removal, aiming to preserve edges, colors, and motion. The tool emphasizes speed and simplicity — there's no setup, no plugins, and the whole workflow is designed to take just a few clicks.

W-Agent is best suited for content creators, video editors, and anyone who needs to quickly clean up footage without paying for a subscription or installing heavy software. It's particularly useful for removing channel logos from archived clips, erasing subtitles from foreign-language videos, or cleaning watermarked images for personal projects. The free pricing and browser-based workflow make it a practical option for occasional use, though the two-minute video limit means it's not built for long-form content.
