Segments.ai review: multi-sensor labeling software for robotics teams
Answer in brief: Segments.ai is labeling software, not a data supplier. It lets your team label 3D point clouds and 2D images together, keep track IDs consistent across sensors and time, project one 3D cuboid into every camera view, and speed up work with ML-assisted tracking and segmentation. It is the only vendor on our list that publishes a price reference: the Core plan starts at 3,600 labeling hours per year, which Segments.ai says equals $2.67 per hour. There is a 14-day free trial, and academic licenses are free.
Verdict: #9. The best tool for teams that label in-house. It has the clearest pricing on the list and a free trial you can start today. Visit Segments.ai →

What Segments.ai does for robot-learning teams
Robots with LiDAR, depth and multiple cameras need labels that agree across sensors. Segments.ai is built around that:
- Multi-sensor labeling: view 2D images and 3D point clouds at the same time, and copy labels from 3D sensors to 2D sensors in one click.
- Batch Mode: see every instance of an object across a sequence on one scrollable screen. Fixing one cuboid updates the others.
- Merged point cloud: combine every frame of a sequence into one cloud so sparse static objects get tight cuboids on the first attempt.
- ML tools: keyframe interpolation, automated cuboid tracking, Superpixel 2.0, Autosegment, a Segment Anything integration, and import of your own model's pre-labels.
Who it fits best
Segments.ai fits robotics and AV perception teams with their own labelers, or a labeling partner, that want strong multi-sensor tooling, an API and SDK, and cloud-bucket integrations.
Strengths that set it apart
- Point clouds of unlimited size are split into 3D tiles for fast loading. The Core plan caps clouds at 500,000 points each.
- Unlimited seats, projects and API/SDK access on every plan.
- Testimonials on its site come from robotics users at OCIUS Technology and Cartken.
- Self-serve setup, so you can make changes without waiting for an account manager.
Honest drawbacks
- It is a tool, not a data supplier. Labeling-as-a-service comes through partners Segments.ai introduces, and the Fusion plan includes access to an experienced labeling workforce.
- Sensor-fusion interfaces start on the Fusion plan, not Core.
- It does not collect demonstrations.
Pricing model
Custom quotes on annual labeling-hours plans. Core starts at 3,600 hours per year, which Segments.ai says equals $2.67 per hour. Fusion starts at 5,000 hours per year and adds sensor fusion, webhooks and priority support. Enterprise includes 150,000+ hours per year, custom interfaces, SSO/MFA and a dedicated ML engineer. Segments.ai says it is open to startup-specific options.
Best alternatives to Segments.ai
- Encord: a platform plus managed collection and annotation.
- Kognic: a platform license, managed service or hybrid for camera, LiDAR and radar.
- iMerit: when you want the labeling done for you.
