What CullSnap is

CullSnap is a free desktop app for reviewing, rating, deduplicating, and exporting photos and videos on Linux, macOS, and Windows. Its virtualized media grid uses cached thumbnails to browse large collections; the project says it limits the grid to about 52 DOM nodes. Users can rate images from one to five stars, view EXIF overlays, and trim video segments for export using FFmpeg lossless fast-seek.

Perceptual hashing groups duplicate or burst photos, while image-quality scoring helps select a candidate. CullSnap’s AI scoring runs locally and can assess face quality, sharpness, and aesthetic quality. The optional NIMA aesthetic model requires a manual export; without it, the aesthetic score is absent. Listed formats include JPEG, PNG, HEIC/HEIF, 11 RAW formats, and MP4, MOV, WEBM, MKV, and AVI video. The app can import from phones, cameras, SD cards, and USB drives, with device support varying by operating system and optional dependencies. Cloud Albums supports Google Drive and, on macOS, iCloud Photos. The privacy policy says app data stays local and the app collects no telemetry, analytics, or usage data; Google Drive access and update checks can make network requests. CullSnap is licensed under AGPLv3, with a commercial license for uses unable to comply with its terms.

Who it suits

CullSnap suits photographers who want to sort, rate, compare, and export photo and video collections in a desktop app. It is also a fit for people seeking local AI scoring, duplicate grouping, and optional cloud album access across supported platforms.

What it does well

Groups duplicate or burst photos using perceptual hashing.
AI scoring for face quality and sharpness runs locally.
Supports 11 listed RAW formats and common video formats.
Privacy policy says it collects no telemetry, analytics, or usage data.

What to know first

Device import support varies by operating system and optional dependencies.
The NIMA aesthetic model requires a manual export.
Linux builds require GTK3 and WebKit2GTK.
Only the latest v1.1.x release line receives security updates.

Limits

Getting started

Visit the CullSnap project website on GitHub.
Download the build for macOS, Windows 64-bit, or Linux 64-bit.
On Linux, meet the GTK3 and WebKit2GTK requirements.
Import media from a phone, camera, SD card, or USB drive, depending on operating-system support and dependencies.
Optionally connect Google Drive, or iCloud Photos on macOS, through Cloud Albums.
Manually export the optional NIMA aesthetic model if you want that score.

Verdict

Choose CullSnap for desktop photo and video review with duplicate grouping, local scoring, and export tools, especially if you want a free, open-source app. Look elsewhere if you need the NIMA aesthetic score without manual setup, or if your device-import workflow depends on support that varies by operating system.
