Full control over AI training.
A fully controllable annotation environment.
MobiStudio is a Japanese machine vision AI labelling software based on Label Studio. It is a more customizable alternative to Roboflow: we work directly with each client to introduce tailored labeling tools built around their workflow. This high-performance labeling tool delivers flexible UI design, real-time AI assistance, and team management in one platform.
Design the interface freely according to project requirements.
Optimize everything from button placement to menu structure and display settings for your workflow.
Freely add buttons needed for your project. Configure label types, shortcuts, and placement to match your requirements.
Flexibly modify menu structure and behavior settings per project. Freely configure image display height and label preview count.
Configure automatic page navigation (next/previous) after annotation submission. Reduces manual operations during work, maintaining focus.
Place the tools your work needs — brush size, fast lasso fill, and more — into the panel per project, building the optimal workspace for your field workflow.
Train AI models during annotation work, letting AI assist with the remaining tasks.
Model accuracy improves at each checkpoint, and manual workload decreases progressively.
Training runs at each checkpoint. As model accuracy improves, the manual annotation ratio decreases. Even for a 1,000-image dataset, actual manual work can be limited to approximately the first 150 images.
Train and create your own AI models directly from the MobiStudio interface, then download the trained model and use it in your own applications. No external pipeline required — go from labeling to a deployable machine vision model in one place.
Seamlessly convert between segmentation masks and vector data, and vice versa. Choose the optimal data format for your use case.
| Phase 1 | Manually annotate 150 images, then run 1st model training |
|---|---|
| Phase 2 | Review and correct AI predictions (50% human / 50% AI), re-train at 250 images |
| Phase 3 | High-accuracy AI handles majority (95% AI / 5% human review), complete |
| Result | Up to 80% reduction in work time |
Train object-detection and semantic-segmentation models directly from the screen. Just choose the YOLO version, size, resolution, and target classes to start training.
Beyond rectangular bounding boxes, detect objects with vector polygons that adjust via control knobs.
Fit annotations precisely to an object's contour by simply dragging the knobs.
Drag the knobs placed at each vertex to freely adjust the polygon shape, fitting it precisely to the object's contour.
AI detects the object and auto-generates a vector polygon. Just fine-tune it for a high-precision annotation.
Complex shapes that rectangles can't capture are detected accurately with vector polygons — ideal for inspection and measurement use cases.
Visualize project progress, individual annotation counts, and quality metrics in real time.
Enables data-driven project management.
Real-time display of overall completion rate and remaining tasks. Supports deadline management.
Compare and analyze annotation count, speed, and quality scores for each team member.
Track quality metrics such as agreement rates and correction rates, ensuring consistency of annotation standards.
Control project access permissions with a hierarchical structure of admins, sub-admins, and workers.
Clearly define who can do what and safely manage collaboration in large teams.
Control project creation and editing permissions by role. Eliminates the risk of workers accidentally modifying project settings.
View annotation counts per member in real time. Use for adjusting work allocation and managing progress.
| Typical Labeling Tools | MobiStudio |
|---|---|
| Fixed UI: Compromises needed to fit the project | Fully customizable UI, optimized for your workflow |
| All manual annotation: Enormous time and cost | AI assist kicks in midway, 80% workload reduction |
| Training in a separate tool: Workflow fragmentation | Annotation + training unified in one platform |
| Progress management requires manual compilation | Automatic visualization via statistics dashboard |
| Insufficient permission management | Hierarchical control: Admin / Sub-admin / Worker |
