Check labels against their applications

Upload the label images and the applications, one or hundreds, then press Start. Each application comes back as a row: what matched, what to look at, and where on the label it was read. The tool points things out. You make the call.

Try it:

Label images

Front, back and neck labels as image files, up to 10 MB each. Files named with the application reference first, like COLA-123_front.png, pair themselves.

Drag or upload images

Choose images Choose a folder

Applications

A spreadsheet with one row per application, as CSV (download the template). One row checks one application. Without it, the tool only lists what it reads from each image.

About this tool

What it does

It reads the text on label images with a text-recognition model that runs inside the service itself, compares what it read with what the application says, checks the government warning statement word for word against 27 CFR 16.21, and shows you exactly where on the label it found each item. It works in a few seconds and makes no calls to outside services.

What it does not do

It does not approve or reject applications. Every result is a recommendation for a compliance agent.
It does not store images, application data, or results. Refreshing the page clears everything.
It does not check permits, formulas, class/type validity, age statements or laboratory tolerances.
It does not measure physical type size. Bold type is measured from the print; whenever the measurement cannot confirm it, the warning is marked for you to confirm.

How it decides

Match means the label says the same thing, allowing for letter case and accents. Needs review means it is close but you should look, which is usually OCR noise. Mismatch and Not found mean the label disagrees or the item could not be read. For the warning statement, only an exact match passes.

How this tool is built to be usable

Built with the U.S. Web Design System. Target: WCAG 2.1 AA and Section 508.
Every status is an icon, a word and a color, never a color alone. A pressed button carries a check mark in its text.
Works with the keyboard alone, at 200 percent zoom and on a phone (checked by the browser tests), and in Windows contrast themes (checked by hand); progress, results and recorded decisions are announced to screen readers; moving between pages puts the focus on the new page's heading.
No time limits; the only motion is a progress spinner, which stops when your system asks for reduced motion.

If something does not work for you
