Scanning is no longer limited by batch size—you can now scan your entire photo library at once.
Still worrying about the massive number of similar photos from a single shoot? Are mountains of duplicate images taking up precious storage space in your gallery?
Lumi Sift is a next-generation AI photo culling and management tool designed specifically for photographers, designers, and gallery organization enthusiasts. Powered by robust on-device AI technology, Lumi Sift identifies similar photos, detects blurry outtakes, and flags exposure anomalies with unprecedented precision—helping you effortlessly declutter your library and keep only the best moments.
[Privacy First: 100% Local Execution]
Your privacy is our core priority. All of Lumi Sift's AI computations and image processing are performed entirely locally on your device. No cloud processing, no data uploads, and no account registration required. Every single photo is absolutely safe and will never leave your Mac.
[Seamless Compatibility: Supports Mainstream & RAW Formats]
Whether it's everyday mainstream image formats like JPG, PNG, and HEIC, or RAW image files from major professional camera brands, Lumi Sift can effortlessly parse and process them. It seamlessly integrates into your photography workflow to meet the most rigorous professional demands.
[Dual-Engine Driven: The Perfect Blend of Speed and Depth]
Quick Mode (Lightning-Fast Scanning): Utilizing perceptual hashing technology, it can scan thousands of photos in just seconds. It accurately captures exact duplicates, near-duplicates, and lightly edited images, making it an efficient tool for daily cleanup.
Prime Mode (AI Semantic Understanding): Powered by a robust AI vision model, it possesses human-like "visual intuition." Whether it's different shooting angles of the same scene, similar compositions, or burst shots of the same subject, it can accurately identify and group them together for you.
[Professional Image Quality Analysis]
Beyond deduplication, Lumi Sift is your intelligent photo culling assistant:
Blur & Out-of-Focus Detection: Instantly identify shaky, unusable shots from bursts with a single click.
Exposure Anomaly Flagging: Intelligently analyzes histograms to quickly flag overexposed or underexposed photos.
EXIF Data at a Glance: When reviewing photos, shooting parameters like aperture, shutter speed, ISO, and focal length are clear at a glance. Combined with sharpness scoring, it helps you make the most professional keep-or-delete decisions.
[Efficient Smart Review and Cleanup Workflow]
Similar photos are automatically categorized into clear "sets." Lumi Sift intelligently selects the highest quality and most representative cover image for you. You just need to briefly browse and compare, keep the masterpieces with one click, and the remaining outtakes will be safely moved to the system Trash (recoverable at any time, leaving you with zero worries).
[CLI Productivity Tool for Photographers] (Pro Exclusive)
In addition to an intuitive graphical interface, we also provide a powerful command-line interface (CLI) tool for hardcore professional users. You can seamlessly integrate it into your automated photography post-processing workflow to multiply your processing efficiency.
