Real outcomes
It's not the p-value.
It's the grade.
Epi students lose points for missing a confounder, choosing the wrong study design, or confusing relative with absolute risk. AskSia catches what your TA catches.
3.2->3.8+0.6
For advanced methods I dropped my problem sets into AskSia. Got DAG analysis walked through with backdoor paths identified. Aced the causal inference short answer.
3.0->3.7+0.7
The Mock Exam mode generated epi case studies with auto graded numeric answers. Caught me using RR when OR was the right measure for the case control design.
Why AskSia
Lecture, library, fieldwork, R/Stata session.
Phone for a quick HR check. Laptop in RStudio on the epi homework. Extension pulling Rothman from your LMS. Desktop agent over your senior thesis at midnight. One epi library, four surfaces.
Web App
Where DAGs meet defensible causal claims
Drag Rothman, Kleinbaum, Hernan-Robins, your problem sets, primary lit in. AskSia walks study design, builds DAGs, runs causal inference with proper identification.
Multi-doc Q&A across epi readings with page-level citations
Convert any epi source to Note, Map, Cards, Quiz
Real-time collaboration on shared epi maps
Mobile App
Epi review on the way to fieldwork
iOS and Android. Photograph a study design diagram, a forest plot, or your handwritten DAG. AskSia returns the analysis with confounders identified and bias mechanisms explicit.

Everything in one place
12 study tools built
for college epidemiology.
Stop juggling R for survival, Stata for cohort analyses, ChatGPT for study design (that confuses cohort with case-control), and your TA's office hours. AskSia is one workspace.
Epi lecture transcription
Record your epi lecture. 40+ languages, sub-100ms latency, epi terminology preserved.
OpenEpi multi-textbook Q&A
Drop Rothman, Kleinbaum, Hernan-Robins, your problem sets, and 80 papers. Ask 'why is this cohort study susceptible to selection bias' and AskSia answers with cited proof.
OpenStudy design walker
Walks RCT, cohort, case-control, cross-sectional, ecological designs with strengths, limitations, and the right epi measure (RR, OR, HR, RD).
OpenYouTube to epi notes
Paste any Hopkins BSPH Coursera, Harvard Chan, or Hernán URL. AskSia transcribes, chapterizes, pulls the worked examples into a clean note.
OpenEpi Mock Exam mode
Adaptive practice across MPH epi core, PhD epi qualifying exams. Auto-graded with rationale on design and measure.
OpenSia Note for epi blocks
Turns 200 pages of cardiovascular epi readings into one note: study design, key papers, biostatistical findings, policy implications.
OpenDAG and causal inference walker
