BirdCull vs Cullora

BirdCull is desktop software for reviewing bird-photo burst sequences and selecting stronger candidates. It groups similar images, then scores them using head and eye visibility, sharpness, pose, and differences within each burst. The process is local: BirdCull says photo files, paths, and EXIF metadata are not uploaded. Results can be exported as grouped hard-link folders or star-rated XMP sidecars for Lightroom, Bridge, Photo Mechanic, and similar tools. AI-assisted culling and RAW preview are supported. The free trial processes up to 200 photos per capture date. A full license costs $49 as a one-time purchase, removes the trial batch limit, and includes folder rating output, star XMP output, and email support for purchase and activation issues. One user may activate and use a purchased license. Windows support covers 64-bit Windows 10 and Windows 11. The current Mac package targets Apple silicon Macs with M-series processors, not Intel Macs. For large photo days, BirdCull recommends at least 16 GB of RAM, SSD storage, and local drives instead of network folders. Purchases are non-refundable.

Cullora is a desktop app for reviewing photo shoots and sorting selected images into folders; it is not an editor or catalog. It displays JPEG previews embedded in RAW files without an import step or catalog database, and supports ARW, CR2, CR3, NEF, RAF, ORF, DNG and JPEG. Burst sequences can appear as one grid tile, then open for frame-by-frame review. Pro's on-device Assist can flag closed eyes, soft focus, misfires and exposure issues, but it does not choose, move or delete photographs. Pro also writes ratings and flags to XMP sidecars for Lightroom or Capture One, and exports filtered photos as a static gallery folder viewable without an account or internet. Culling runs locally and works offline; Cullora says photographs are never uploaded. The free tier limits filing to 50 photos monthly anonymously or 200 with an account, while viewing and rating are unlimited. Pro is listed at €49.00 EUR one-time; the platform page offers a Windows beta for Windows 10/11 64-bit and says the macOS build is in progress, not released.
