On-device AI culling · iPhone

The physics of the problem

A 3,000-shot RAW session can't round-trip the cloud.

That session weighs 60–150 GB. Uploading it from a phone is not slow — it's impossible in any reasonable time, on any reasonable plan. So Keepers doesn't try. It culls in place off your card, using the embedded JPEG previews and Apple's Vision framework on the Neural Engine.

Client contracts forbid uploading

Wedding and portrait agreements routinely ban storing images on third-party servers. On-device culling keeps you compliant by default — there's no server to leak.

No GPU bills, no server subscription

Competitors pay for cloud compute and pass it on. Keepers runs entirely on the silicon you already carry, so there's no metered server cost baked into the price.

Reads embedded JPEG previews

Every RAW file ships a full-res JPEG preview. Keepers scores those on the Neural Engine — fast enough to scan thousands of frames without decoding every RAW.

What it actually does

A culling engine, not a filter pack.

Five jobs, all on the iPhone: score every frame, kill the duplicates, surface the keepers, learn your taste, and hand stars straight back to your editor.

Scoring

Sharpness, blink & aesthetic, frame by frame

Each shot gets a composite score from real signals — focus sharpness, eye-open / blink detection, face capture quality, and an aesthetic model. Thermal-aware batching scans thousands of RAW frames in minutes without cooking your phone.

Bursts & dupes

Best-of, picked for you

Near-duplicate grouping collapses a 12-frame burst to the single sharpest, best-expression keeper.

Taste model

It learns the way you pick

Every accept and reject trains a personalization model on-device. Over a few sessions, the shortlist starts to look like the selects you'd have made by hand — your eye, scaled.

Lightroom & Capture One

Lossless XMP round-trip

Stars, picks and color labels export as sidecar XMP straight back into Lightroom Classic or Capture One. Nothing is baked, nothing is destroyed — you finish exactly where you already edit.

Four steps, one device

From card reader to Lightroom — without a laptop.

Plug in the card

Connect your USB-C card reader or SSD straight to the iPhone. Keepers reads RAW frames in place — no import, no copy.

Scan in minutes

Thermal-aware batch scoring runs thousands of frames on the Neural Engine — sharpness, blinks, faces and aesthetics, fast.

Get the shortlist

Bursts collapse, duplicates merge, keepers rise to the top. Review the shortlist and adjust — it learns from every call.

Export to Lightroom

Stars and labels write out as lossless XMP. Open Lightroom Classic or Capture One and your selects are already there.

Questions

The things photographers ask first.

Do my photos ever upload anywhere?

Never. Keepers runs entirely on the iPhone using Apple's Vision framework on the Neural Engine. Your photo bytes stay on your card and your device — 0 bytes are uploaded. There is no Keepers server holding your images, which is exactly why it works within client contracts that forbid uploading wedding or portrait files.

Which formats and cameras are supported?

RAW from the major camera makers (Canon, Sony, Nikon, Fujifilm and more) plus JPEG. Keepers reads the full-res JPEG preview embedded in each RAW for fast scoring, so it scans thousands of frames without decoding every file.

How does it cull a 60–150 GB session on a phone?

It doesn't move the session — it reads it in place off your USB-C card or SSD. Scoring runs on the embedded previews via the Neural Engine, with thermal-aware batching so a 3,000-frame session finishes in minutes without overheating the phone.

Will my edits transfer to Lightroom?

Yes. Stars, picks and color labels export as standard sidecar XMP, lossless and non-destructive. Import the folder into Lightroom Classic or Capture One and your selects and ratings are already applied.

How is this different from Aftershoot and other AI cullers?

Those tools proved photographers will pay for AI culling — but they're desktop-only and lean on the cloud. Keepers is mobile-native and fully on-device: cull straight from the card on your phone, between the ceremony and the reception, with nothing uploaded and no server subscription.
