Segments.ai review: the self-serve labeling layer for data from your robotics data provider

Answer in brief: Segments.ai does not collect robot data. It is a multi-sensor labeling platform for robotics and AV teams that already have camera and point-cloud data, whether from their own robots or a collector on our list. It labels 2D and 3D together with consistent track IDs, projects 3D cuboids onto 2D images, and handles point clouds of unlimited size on higher plans. It offers a 14-day free trial. The Core plan is a custom quote that starts at 3,600 hours a year of labeling usage, which Segments.ai equates to $2.67/hour.

Top pick for: engineers who want to own their labeling workflow. Self-serve setup, a Python SDK, and an option to outsource to labeling partners.

Where Segments.ai fits in a collection program

Embodiments. Segments.ai works on any robot's camera and point-cloud logs. Its site features off-road, delivery and maritime robotics users. It does not collect demonstrations or footage.

Scale. Point clouds of unlimited size are split into 3D tiles for fast loading. Plans are sized by labeling usage: Core starts at 3,600 hours a year, Fusion at 5,000, and Enterprise includes 150,000+.

Delivery. A Python SDK, API keys and webhooks connect it to your pipeline. Exports work with PyTorch, TensorFlow and Hugging Face, and model-assisted pre-labels can be uploaded for correction.

Built for

• Robotics engineers labeling their own sensor logs.
• Teams that receive raw multi-sensor data from a collector and want control over labels and QA.
• Startups and researchers. Free academic licenses are available, and Segments.ai says it is open to startup arrangements.

Where Segments.ai wins

• True multi-sensor labeling. Synced track IDs across modalities and time, plus one-click 3D-to-2D projection.
• Smart 3D tools. Merged point clouds for stationary objects, batch mode for moving ones, and ML cuboid propagation on the Scale and Enterprise plans.
• ML-assisted 2D. Superpixel 2.0, Autosegment, hover-and-click Segment Anything, and pre-labels.
• Transparent entry point. A free trial and a published usage-hour equivalent on the Core plan.

Where it falls short

• Labeling only. It does not collect demonstrations or footage.
• The Core plan caps point clouds at 500,000 points each. Unlimited size and sensor-fusion interfaces need the Fusion plan.
• Managed labeling comes through partner agencies rather than an in-house workforce.

What it costs

All plans are custom quotes. Core includes a 14-day free trial and starts at 3,600 hours a year of labeling usage (equivalent to $2.67/hour). Fusion starts at 5,000 hours a year and adds sensor fusion and access to an experienced labeling workforce. Enterprise includes 150,000+ hours a year, SSO and a dedicated solutions ML engineer.

Shortlist these instead

• Encord: collection plus a labeling platform from one vendor.
• Sama: managed multi-sensor labeling with a written quality guarantee.
• iMerit: managed robotics labeling plus egocentric collection.

Quick answers
