copsy (verb): to copy a card and verify it

Plug in the card and
Copsy it to the drive.

Copsy reads what is on the card, copies it, and verifies every file — the whole offload in one app.

Made by a working DIT: copsy a card to your drive, mirror it to Google Drive or Dropbox, and get a Telegram when it is verified.

Copsy reads the card first

Sony, ARRI, Blackmagic, RED, Canon, drones and audio recorders are recognized by what is on the card, not by the label on it.

📁

Copsy sorts as it copies

Camera_A, Camera_B, Drone, Audio — every clip lands in a folder by date and source. Nothing left to rename at 1 AM.

☁️

Copsy to two places at once

Your drive and Google Drive or Dropbox fill in the same pass, so the cloud backup is done when the card is done. If the Wi-Fi drops it picks up where it left off.

🔔

Copsy pings the whole crew

A Telegram message the second a card is copied and verified, so nobody has to ask whether the card can be wiped.

Built to film-set standards

The same verification process Netflix-spec DITs use — automated.

Not a hobby tool. Every copy is byte-verified, manifest-stamped, and audit-ready before the producer even asks.

🔐

ASC-MHL checksums

Every file is hashed on source and destination, then compared. An ASC-MHL manifest — the same format used on professional film sets — is written alongside every copy, so the next link in your chain can re-verify in one click.

🎬

Netflix-spec delivery

Folder structure, file naming, and verification reports match Netflix delivery requirements. Hand your drive to a post house without a written explanation.

📄

Producer PDF report

Auto-generated after every copy: thumbnails, file counts, sizes, durations, and a green verification badge per card. The handover paperwork writes itself.

Copsy Monitor on iPhone showing a live card copy and a parallel Google Drive upload

In development

Watch the offload from your pocket.

Copsy Monitor is a companion app for iPhone and iPad. It mirrors the Mac's live copy and cloud-upload progress over your own Wi-Fi — so you stop walking back to the machine to check a progress bar.

  • Live progress — percent, MB/s, files and ETA for every card and every cloud upload.
  • Remote control — start a copy, cancel one, or eject a card on the Mac.
  • Your Wi-Fi only — token-protected, with nothing routed through a server.

Not released yet — there is no download for the phone app today. The Mac app is free and ready now.

What is Copsy?

Copsy is a free Mac app that copies footage off camera memory cards. To copsy a card is to plug it in and let one app do the rest. Copsy detects the card by content — Sony, ARRI, Blackmagic, RED and Canon cameras, drones and audio recorders — copies it to an external drive and, if you want, to Google Drive or Dropbox in the same pass. Every file is verified with ASC-MHL checksums, the film-set standard, so you can prove each clip copied bit for bit. Clips land in folders by date and source, a delivery report is written, and Telegram tells you the card is safe. Copsy does the core offload work that Hedge, OffShoot, ShotPut Pro and Pomfort Silverstack charge for, at no cost, on macOS 13 or later.

Copsy is made for DITs, data wranglers, filmmakers, video producers, wedding and event videographers, documentary shooters, drone operators and photographers, anyone who answers for the footage. It does the core job of those paid offload tools at no cost, with no signup, no card limit and no paywall. Today Copsy is a Mac app, running on macOS 13 or later, with a Windows version coming soon, so the same content-aware detection and checksum-verified offload reaches more of the set.

Free. No signup, no account.
