Annotate

Fast, keyboard-driven image classification tool. Runs locally in your browser.

Installation

git clone <repo-url>
cd annotate
npm install
npm run dev

Open http://localhost:3000.

How to Use

1. Click Select Image Folder and pick a folder of images.
2. Use keyboard shortcuts to annotate:

Key	Action
P	Label as Positive, advance to next
N	Label as Negative, advance to next
→	Next image (no label)
←	Previous image

3. Optionally edit label names in the right panel and click Save Labels.
4. Click Export CSV or Export JSON to download your annotations.

Please note again that default label texts are Positive and Negative, you can change it as needed, such as Tangling,Not-tangling, then save them.

Notes

• Images never leave your machine — loaded as blob URLs directly in the browser.
• Requires a Chromium-based browser (Chrome, Edge) for the folder picker.
• Re-picking a folder resets annotations.
