What it is
T-Rex Label is an AI-assisted annotation tool for computer vision datasets. Instead of drawing a bounding box on every instance of an object by hand, you select one object as a visual prompt and the DINO-X model automatically finds and labels every matching object across the rest of your images. It has a free tier to start, with paid credits for larger batch jobs.

What you get free vs paid
Verdict
Pros
- One-click labeling: select one instance and it auto-labels every similar object
- Zero-shot detection handles rare or unusual objects without custom training
- No installation or model fine-tuning required, runs in the browser
- Batch processing for annotating entire image libraries at once
Cons
- Free tier is credit-limited, so large datasets will eventually need a paid plan
- Automatic matching still needs a manual review pass on dense or cluttered scenes
- Narrow focus on annotation means you still need a separate tool to train the actual model
A genuinely useful time-saver if your bottleneck is manual bounding boxes, especially for rare-object or dense-scene datasets where writing a custom detector isn't worth it.
