How It Works

How Cullit Actually Works

You shoot 800 frames, only a fraction are true keepers, and manual culling steals your night. Cullit handles the first pass so you spend less time clicking and more time delivering.

What We Analyze

Sharpness

Motion blur, focus confidence, and shake patterns.

Exposure

Highlight clipping, shadow crush, histogram balance.

Composition

Framing strength, horizon, spacing, visual structure.

Faces & Timing

Eyes, expressions, subject presence, and moment quality.

The Algorithm Ladder

Each tier runs genuinely better technology. This is not marketing — it's a real technical stack difference. Higher tiers catch edge cases the lower tiers miss.

Free Trial

OpenCV Baseline

Pure computer vision: Laplacian blur detection, histogram exposure analysis, Haar cascade face detection, rule-of-thirds composition, perceptual hash duplicate removal. Fast and reliable for obvious keeps and culls.

Starter — $5/mo

OpenCV + Deep ML

Upgrades face detection to MTCNN (neural network) — catches side profiles, low-light faces, and partial occlusions that Haar misses. Adds NIMA aesthetic scoring (trained on human ratings) for photo quality beyond technical correctness.

Pro — $15/mo

ML + AI Judgment

Photos the ML stack marks as ambiguous get a second pass from Claude Haiku AI vision. The AI evaluates moment quality, subject emotion, and context that pixel-level metrics cannot capture. Catches the shots that feel wrong despite good technicals.

Studio — $25/mo

Full AI Vision

Claude Sonnet AI vision runs on every non-obvious photo — full scene context understanding, emotional timing detection, subject-awareness beyond faces. The highest accuracy pass for professional delivery.

We show you exactly which signals each tier checks in the pricing modal. No black boxes.

Star System

★★★★★ Portfolio Worthy

Hero shots: sharp, strong composition, exact moment.

Website portfolio, hero carousel, social highlights.

Typical rate: 2-5% of a shoot.

★★★★ Solid Selects

Client-ready storytelling frames.

Delivery gallery, album sets, print choices.

Typical rate: 10-20% of a shoot.

★★★ Backup Options

Technically usable but less compelling.

Archive backups and alternates.

Typical rate: 20-30% of a shoot.

★★ Probably Cull

Minor misses: soft focus, weak expression, timing miss.

Keep only if no stronger alternative exists.

Typical rate: variable by shoot type.

★ Definitely Cull

Clear misses: blur, eyes closed, bad exposure, weak duplicate.

Reject with confidence.

Typical rate: depends on burst style and lighting conditions.

What We Don't Do

  • We do not edit, retouch, or color-grade your photos.
  • We do not make your final keep/reject decision for you.
  • We do not promise perfect accuracy on every edge case.
  • We do not keep your source photos after processing workflow completion.
