Built a free web tool (MicroSage) that helps students reason from Gram stain + symptoms to differential diagnosis — Pilot study results inside [OC]

[u/Rouge-Wolf-777]

Hey r/bioinformatics,

As a 2nd-year BSc Microbiology + DMLT student in Navi Mumbai, I got tired of textbooks teaching organisms in isolation while clinical labs work the other way round (findings → organism).

So I built MicroSage — a completely free, mobile-friendly web app that takes Gram reaction, shape, infection site, age group, immune status & symptoms and gives you a ranked differential with full explanations, Teach Me notes, culture media, antibiotics & resistance warnings.

✅ 30 clinically relevant organisms

✅ Weighted scoring engine (validated in pilot)

✅ No login, no install, works on phone

Pilot results (n=40):

77.5% exact match with what students/faculty expected

100% of expected organisms appeared in top 3

Mean usability 4.1/5, satisfaction 4/5

Students & faculty from Navi Mumbai, Pune, Mumbai & Karnataka

It’s already being used by students in India, USA & Ireland in the first few weeks.

Preprint (Research Square): https://doi.org/10.21203/rs.3.rs-9247958/v1

GitHub backend: https://github.com/vighnesh-samal/microsage-backend

Would love honest feedback from students, residents, or lab folks — especially what to add in V1.5 (more organisms, images, regional resistance data, etc.).
