About

Synapse Evals

Features
Read full description

Synapse Evals is the voice-first evaluation platform built for medical residency programs. Attending physicians record feedback verbally — no typing, no forms, no friction. Synapse transcribes the recording and delivers it directly to the resident. Program directors get a real-time compliance record without the administrative burden. DESIGNED FOR HOW ATTENDINGS ACTUALLY WORK Voice recording takes seconds between cases. No keyboards, no login hassles, no end-of-month scramble to remember what happened. The result: residents get more feedback, faster, and of higher quality. FOR RESIDENTS Receive feedback immediately after it's recorded. Review every evaluation submitted for you across your residency — timely, specific, and coming from attendings who aren't bogged down by paperwork. FOR PROGRAM DIRECTORS A live dashboard showing every evaluation submitted across your program. Generate AI-powered summaries across large volumes of evaluations to build cases or prepare for resident round tables. Export-ready documentation for ACGME compliance. Manage your full roster of residents and evaluators. BUILT FOR PRIVACY Voice recordings are transcribed and immediately deleted — only the text is stored. Feedback stays within your program. No data is shared across programs or institutions. Synapse Evals is for attending-to-resident clinical education feedback only. It is not a patient record system and should never be used to record or transmit patient information.
