Digital pathology annotation for pathologists
Computational pathology models learn from expert-drawn regions and cell labels on whole slide images. Annotate histopathology and cytology remotely, choose the projects you take on and work at your own hourly rate.
What pathology annotation involves
Tumour region outlining
Draw polygons around invasive tumour, in-situ components, necrosis and stroma on H&E whole slide images.
Cell counting and classification
Mark mitoses, lymphocytes and tumour cells, and score biomarkers such as Ki-67, HER2 and PD-L1.
Tissue classification
Label tissue types and grade tumours across biopsy and resection slides.
Cytology review
Classify cells and flag atypia on cytology smears and liquid-based preparations.
Typical tools: QuPath, ASAP, CVAT, Aperio ImageScope.
Who we look for
- Board-certified pathologists
- Pathology residents
- Cytotechnologists and biomedical scientists
- Dermatopathologists and haematopathologists
Pathology annotation questions
Can pathology annotation be done remotely?
Yes. Whole slide images are streamed in a browser-based viewer, so you annotate from home without downloading slides.
What kinds of slides will I annotate?
Mostly H&E-stained histopathology, plus immunohistochemistry and cytology depending on the project. Each project comes with written guidelines.
Do I need experience with QuPath?
No, but it helps. Tell us which tools you have used when you apply. Your diagnostic expertise matters most.
How is pathology annotation paid?
You set your own hourly rate when you register. You see each project's scope, slide volume and budget before you accept.
