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.
Try it here: https://microsage.vercel.app
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.).
