Smear Camera — teach STAINIC to read Albert

Snap the smear, film or microscope field with your phone camera, or upload a microscope camera image. Photos help STAINIC learn stain patterns so it can suggest findings in future.

Mobile data / Wi-Fi

Each photo (1-12 MB) is uploaded over your internet connection. On mobile data this uses your data plan and may incur charges; prefer Wi-Fi for many photos.

How AI will use photos

Photos are kept in a separate STAINIC image library (not your storage quota) to build future machine-learning models that recognise stain patterns and suggest findings. No AI analysis runs on them today and nothing is auto-filled yet.

Disclaimer

Photograph only the smear / film / field — never patient names, labels, faces or documents. Photos are not linked to any patient. Future AI suggestions will be decision-support only and must always be verified by a qualified pathologist; they are not a diagnosis or treatment advice.
