Why it's different

Built for the workflow, not the demo

Six things that actually matter when you shoot in volume for a living.

⚡

Speed, with receipts

692 images a minute, measured on real hardware — not a marketing adjective. See the full numbers on the How it works page.

◎

Trustworthy culling, not blind auto-delete

Blur, exposure, blink, and near-duplicate detection are computed once and shown, not hidden. You move the thresholds — nothing vanishes without you seeing why.

✓

AI metadata that meets the standard

21 analysis types, written to real IPTC/XMP fields, following the exact keyword caps and ordering rules stock platforms actually grade against.

🔒

Local-first, by architecture

The vision model runs embedded, on your machine. There is no server this product talks to for image analysis — nothing to misconfigure, nothing to disable.

📜

Provenance you can hand to a client

Every export carries C2PA Content Credentials — the open industry standard for content provenance — as verifiable proof the delivered image is a real camera capture with a traceable edit history.

◐

Feels like the tool you already use

A familiar grid, slider, and lightbox interaction model. The payoff is speed and metadata — not a workflow re-education.

The pipeline

Import → Cull → Process → Review → Export

One continuous flow from a card full of RAW files to a delivered, signed, fully-keyworded set.

1

Drop in a shoot — RAW included

Point BLOCK WORKS at a folder or a card. It ingests everything, including RAW, and lands the whole set on a staging lightbox in the time it takes to make coffee.

  • ✓ 692 images/minute sustained, measured on real hardware
  • ✓ RAW decode handled automatically, no side conversion step
  • ✓ Nothing leaves your machine to get there

2

Cull with sliders you control

Blur, exposure, blink, and near-duplicate scores are measured once per image. Move the thresholds and watch the grid re-sort live — nothing is silently deleted, ever.

  • ✓ Live threshold sliders, sub-millisecond re-evaluation at 2,000+ images
  • ✓ Burst and near-duplicate clustering, keep-best in one click
  • ✓ Keyboard-only culling for speed shooters (P/X/U, star ratings, color labels)

Let AI write the metadata

Every keeper gets 21 analysis types — keywords, captions, titles, themes, mood, setting, activities, objects, colors, on-image text, and more — written to real IPTC/XMP fields.

  • ✓ Follows Adobe Stock-style keyword caps and ordering, not generic AI tags
  • ✓ Runs on an embedded, local vision model — nothing sent anywhere
  • ✓ A human reviews before anything ships — never blind auto-export

Export, signed and ready

EXIF and IPTC/XMP metadata are written straight into the file. Every export carries a C2PA Content Credentials manifest — the open industry standard for content authenticity — proof it's a real capture, not synthetic content.

  • ✓ No side-car files, no metadata stripped by the next tool in your chain
  • ✓ Signed with C2PA Content Credentials, verifiable by anyone downstream
  • ✓ Deliver with a project report, not a folder and a hope

Real analytics from a real machine

Every number here is measured, not marketing copy — including the cost line.

Culling is the worst part of a photographer's job, and most tools that try to fix it ask you to trust a black box. BLOCK WORKS shows its work — live thresholds, visible scores, nothing removed without you seeing why.
