Features & Capabilities

Spreadshirt Copyright Assistant is a productivity and compliance tool designed for teams working in Spreadshirt’s Production Cockpit.

The extension automatically scans product images using fuzzy image matching techniques and compares them against a customizable blocklist of known copyrighted designs. When a match exceeds the configured similarity threshold, the image is clearly flagged and the associated order is tracked for review.

A floating in-page control panel provides full visibility and control without leaving the Cockpit interface. Users can manage blocked image hashes, adjust similarity thresholds, review affected orders, and quickly open orders for inspection.

This add-on is intended to assist human review workflows, reduce manual checking, and help teams respond faster to potential copyright issues. It does not automatically block or modify orders on the platform.

Is Spreadshirt Copyright Assistant Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Spreadshirt Copyright Assistant requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
