Local ML Model Workbench
Run, test, annotate, train, or fine-tune ML models and datasets locally for ML practitioners.
RectLabel Pro
The one-time-payment edition of RectLabel, offering the same fully offline SAM/Cellpose/Core ML annotation power, and the better value pick in Local ML Model Workbench. At a flat $19.99 with no subscription, it's the recommended way to get this on-device labeling toolkit.
- +All on-device ML labeling features (SAM 2/3, Cellpose, RF-DETR, YOLO26) with no subscription
- +Flat $19.99 one-time price; exports YOLO/COCO/CreateML/DOTA; fully offline
- −Niche, expert-oriented tool with no ratings to gauge polish
- −Functionally identical to the standard app, just different pricing
Open Otter
A serious power-user pick for the Local ML Model Workbench: it runs open models natively on Apple Silicon via MLX, exposes a drop-in OpenAI server, and even supports distributed multi-Mac inference. What sets it apart is the hardware monitoring dashboard, SSD-backed KV cache, and built-in on-device vector DB for RAG.
RectLabel
A best-in-class offline annotation tool for object detection and segmentation, exactly the kind of app Local ML Model Workbench exists for. It runs Segment Anything, Cellpose, and Core ML auto-labelers entirely on-device and exports to YOLO/COCO/CreateML/DOTA, making it a serious practitioner pick.
