Left Sidebar — Study Browser for loading slides, annotation tools, and AI analysis controls
WSI Canvas — the main whole-slide image viewport with pan, zoom, and overlay rendering
Right Sidebar — Analysis, Report, and Case tabs for quantitative data and exports

Loading Slides
The Study Browser in the left sidebar gives you three ways to open a slide:
My Slides — uploads you've added via the URL/DZI input or linked slides
Public Library — curated reference slides available to all users
URL / DZI input — paste any publicly accessible DZI manifest URL to load a remote slide instantly
Study Browser panel showing slide list and URL input
03
Annotation Tools
Enable Annotation Mode from the left panel to unlock the full toolset:
Shape picker — Circle, Square, Pin, Freehand, or Polygon
Color swatches — assign a color to distinguish annotation categories visually
Tissue labels — Tumor, Stroma, Immune, Vessel, Necrosis, or a custom name
Click or drag on the canvas to place annotations after selecting a shape.
Annotation toolbar with shape and color controls
04
AI Analysis
The Run AI Analysis button (left panel, below annotation tools) sends the current viewport region to the detection model. Once complete, probability heatmaps overlay the canvas.
Use the probability threshold slider to filter detections by confidence — drag right to show only high-confidence regions. The model detects mitotic figures, tumor cell clusters, and stromal boundaries depending on the stain protocol.
Tip
AI analysis runs on the current viewport region only. Pan to a new area and run again to analyse the full slide progressively.
05
Channel Mixer
For fluorescence slides (e.g. DAPI/FITC/TRITC stained), the Channel Mixer panel lets you independently control each channel:
After submission, annotations lock and the ground-truth overlay becomes available for self-review
Instructors
Create cases and add ground-truth annotations at /instructor
Build courses and assign case sets to student groups
Track submission and annotation progress per student in the instructor dashboard
Diagnosis and ground truth are revealed to students only after submission
Submit Flow
When a student clicks Submit Case, all annotations lock (no further edits), the instructor's diagnosis is revealed, and the ground-truth annotation overlay becomes available so the student can compare their work against the expert's.
