PhotoMentor vs Aftershoot for Photo Culling
Both products reduce a shoot to a reviewable selection and send ratings back to Lightroom Classic or Capture One. Aftershoot is a desktop app that works locally and offline. PhotoMentor Bulk Culler runs in the browser, uploads only reduced previews so RAW files stay on your computer, ranks keepers against a written brief and gives reasons for each finalist.
Cull your first shoot freeSide-by-side criteria
| Criterion | PhotoMentor Bulk Culler | Aftershoot |
|---|---|---|
| Verified product scope | PhotoMentor Bulk Culler: browser-based culling of a whole shoot. The AI sort puts photos into Keep / Review / Rejected and groups similar frames; keepers are ranked into a shortlist with reasons, and a detailed critique is available for finalists. | AI culling (Select) inside a wider desktop product that also offers editing, retouching and galleries. |
| Where the workflow runs | In a desktop browser (Chrome, Edge, Safari or Firefox). Analysis runs on PhotoMentor servers, so an internet connection is required. There is no desktop app. | Windows and macOS app. The official page says it works locally and offline: “Images never leave your machine.” |
| Files and RAW input | JPG, PNG, WebP, HEIC/HEIF and camera RAW (CR2, CR3, NEF, NRW, ARW, RAF, ORF, RW2, PEF, SRW, DNG and more). For RAW, the browser reads the preview the camera embedded in the file; RAW+JPEG pairs count as one photo. Only a reduced copy (long side up to 1024 px) is uploaded: RAW and full-size files stay on your computer. | RAW and JPEG files from all major camera brands, according to the official FAQ. HEIC is not mentioned on the reviewed page. |
| Handoff to your editor | Stars, colour labels, statuses and keywords as XMP sidecars for Lightroom Classic and Capture One. In Chrome or Edge they are written into the shoot folder and merged with existing sidecars: develop settings saved in them are never touched, and stars and labels saved in them are kept unless you choose to overwrite them. Save metadata to files in your editor first; changes kept only in the catalog are replaced when the editor reads the sidecars. Other browsers download a ZIP. Photo files are never modified. JPEG, HEIC and DNG get a file-name list for a Lightroom filter; CSV and HTML reports are also available. | Export to Lightroom Classic, Capture One and local storage, preserving star ratings, colour labels and flags; the FAQ says ratings for RAW workflows are typically written to XMP sidecars. Photo Mechanic and Bridge are also listed as integrations. |
| Similar frames and shortlist size | Similar frames are grouped and can be compared side by side. You choose how many finalists you need, up to 100 (presets 10 / 25 / 50 or a share of the session), and can pin photos you want regardless of rank. | Groups duplicates and near-identical burst shots and keeps at least one image from every duplicate group. Cull to Target builds the selection around a target photo count. |
| Selection context | Two modes for the AI sort, Event / reportage and Creative / personal work, plus an optional written brief (theme and audience, weights in %) that ranks the keepers before any critique. | Quality ranking across many factors (sharpness, exposure, blinks, composition and more), strictness from lenient to strict, and an AI that learns from what you keep and skip. A free-text brief is not described. |
| Deliberate creative choices | In Creative / personal work mode, silhouettes, motion blur, fog, grain and unusual exposure are treated as possible intent: at worst such a photo goes to Review and it is never rejected for that reason alone. The AI shows which deliberate choices it recognised. | No creative or personal-work mode is described on the reviewed page. It says the AI differentiates “true duplicates from intentional variations”, and strictness can be adjusted. |
| Decision explanation | Readable reasons for every finalist (“why this photo”). A detailed critique runs automatically for a plan-dependent number of finalists and on request for any other photo. | Image scoring and rating buckets (Selected, Highlights, Closed Eyes, Blur, Duplicates). The reviewed page does not describe a written reason for each selected photo. |
| Photographer control | Every status is a suggestion. Review with keyboard shortcuts, stars, colour labels, multi-select and undo, and override anything; the photographer makes the final call. | AI-automated and AI-assisted modes, Survey Mode, Spray Can, grid, side-by-side and Loupe views; any selection can be overridden and nothing is deleted. |
| After the cull | Culled shoots stay searchable in All Photos by description or “find similar”; older shoots can be added to search without culling on the Workflow plan. Collections group photos across shoots, and in Chrome or Edge a package of the original files can be assembled from your own disk (SHA-256-verified copies; originals are never uploaded). | People Filters find a person by name within the album in Cull, Edit or Retouch. Search across past shoots is not described on the reviewed page. |
| Best fit | A browser workflow that keeps RAW files on your computer, with a written brief, a Creative mode, reasons for each finalist and search across past shoots. | Offline desktop culling with established Lightroom Classic and Capture One handoff and a target photo count. |
When Aftershoot may be preferable
Aftershoot may be preferable when you need to cull without an internet connection, want images processed entirely on your own machine, want an AI that adapts to what you keep and skip, or want culling, editing and retouching in one desktop app with export to Lightroom Classic, Capture One or local storage.
When PhotoMentor Bulk Culler may fit
PhotoMentor Bulk Culler may fit when you prefer a browser to installing an app, want to describe the theme and audience of the selection in your own words, need a mode that does not punish deliberate motion blur, grain or silhouettes, want readable reasons for each finalist, or want to find photos again across all your culled shoots. It needs an internet connection, and writing sidecars straight into a folder works in Chrome and Edge.
How to decide

Questions
Is PhotoMentor Bulk Culler a replacement for Aftershoot?
Not in every workflow. Aftershoot’s official page describes a local desktop app that works offline. PhotoMentor Bulk Culler runs in the browser and needs an internet connection; you install nothing, RAW files stay on your computer, and the ranking follows a written brief with reasons for each finalist. Choose around the workflow you actually need.
Can both send ratings to Lightroom Classic and Capture One?
Yes. Aftershoot’s official page says star ratings, colour labels and flags are preserved on export to Lightroom Classic and Capture One. PhotoMentor Bulk Culler writes stars, colour labels and keywords as XMP sidecars and merges them with existing sidecars without touching the develop settings saved in them; save metadata to files in Lightroom first.
Does PhotoMentor claim to be faster or more accurate?
No. This comparison does not present a measured speed or accuracy result. Test both with a representative session and inspect the selections yourself.
