How it works (workflow)
Annotate images with polygons, rectangles, and more. Validate & export annotations as a dataset.
Products (what we provide)
AI-powered annotation app, automation-ready tools & guides to build high-quality datasets.
Examples (what you can do)
Self-driving, retail, agriculture, medical, and more. Build datasets for various computer vision tasks.
Story (how we got here)
Automation obsessor. Solo-built Labelme (15K+ stars), GH 9+ Top trending. PhD, Lead CV at Mujin.
Examples
Make image annotations for any applications with any shapes & AI-assist.
How it works (workflow)
1. Annotate images with polygon, rectangle, or any shapes with Annotation app
2. Validate & export annotations as a dataset with Tookit
3. Train your AI model
How Annotation app works
Easy-to-use UI
Everything you need in a single window.
Offline & private
Keep data private & work confidently.
Any shapes
Polygon, rectangle, circle, line, & more.
Rich attributes
Add details (flags, texts) to annotations.
Annotation app
Offline-first app you download and run on your computer.
How Toolkit works (automation)
Batch process
Annotate, edit, validate, and export many at once.
The toolkit streamlines dataset creation and complements manual annotation.
Automation ready
Integrate with your workflow and other tools.
The app and toolkit are accessible from CLI, easily connectable.
Toolkit
Command-line tools to streamline dataset creation.
How AI works (annotation app & toolkit)
Prompt to annotations
Type what to annotate, to get it annotated with AI.
AI annotates objects with rectangles that best match your text prompt.
A click to annotation
Instant object annotation by a few clicks with AI.
You'll get real-time feedback. Tweak clicks on the fly, or the polygon later.
Rectangle to polygon
Convert rough rectangles to accurate polygons with AI.
Perfect for objects with complex shapes (e.g., irregular, curved).

Hi, I'm Kentaro!
Here is the story behind Labelme.
I built it when I was at the end of my bachelor's degree / beginning of my master's. I was working in a robotics lab and created it to teach my robot to see the world.
Around 2015-2016, Amazon Robotics held the Amazon Picking Challenge (APC) shortly after acquiring Kiva Robotics, the company who developed the AGVs used at Amazon. They had automated material delivery in warehouses but were looking for an automation solution for material picking.
We participated as a team from the lab (Can you spot me in the picture?), and I ended up building Labelme for the challenge.
For the full story, check out my tweet.
