Features and benefits

Secure messaging
Securely exchange messages, photos, videos, and files with end-to-end encryption. Doctolib Siilo enhances protection with PIN, facial, or fingerprint recognition and masked notifications for confidentiality. Ideal for tele-expertise, it enables healthcare professionals to communicate securely, share medical information, and seek expert opinions while ensuring strict patient data confidentiality.

Siilo Medical Directory
Search for and connect with verified healthcare professionals on Doctolib Siilo without needing their contact details. You can use criteria such as name, area of expertise, location, or other profile details to make new connections.

Create a patient case
By creating a patient case, you can store all media and conversations about a specific patient together, separate from the rest of your chats. A case can also be easily exported as a PDF file for the EHR.

Capture and store photos securely
Photos and videos taken with the secure camera or uploaded to Doctolib Siilo are stored in Siilo’s encrypted media library, not in your personal photo gallery.

Edit photos
The ‘Edit’ function offers two tools for photo editing. The ‘Blur’ tool allows you to permanently anonymise parts of images that should be kept private, while the ‘Arrow’ tool draws a red arrow to highlight specific details in the image.

Voice and Video Calling
Communicate securely with your colleagues in real time when SMS isn’t suitable. Make voice or video calls directly from the chat screen, or call via a colleague’s profile, all in a secure environment.

Availability Status
You can install an out-of-office reply for when you have time off, or simply switch to ‘unavailable’ when you temporarily can’t be reached due to consultations or operations.

Dark Mode
Prevent eye fatigue during the night shift by enabling Dark Mode. Activate it manually to change the Doctolib Siilo interface or sync with your device settings for automatic transitions.

Access Doctolib Siilo on your Desktop
In addition to the mobile app, you can also access Doctolib Siilo through your browser at web.siilo.com. But you can get there even faster: install Siilo for Desktop on your computer. With Siilo for Desktop, you will have access to the messenger anytime, anywhere.
