As answered by people managing totallynot.ai and Diffyn.
totallynot.ai's answer
totallynot.ai is the only clinical AI reference tool designed to be completely invisible. The interface looks exactly like a plain text editor or notepad — no search bar, no medical branding, no obvious AI elements. It's built specifically for discreet bedside use so clinicians can look up drug dosing, differentials, and interactions without patients or attendings noticing. Most clinical tools are obviously medical apps; totallynot.ai is intentionally camouflaged.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
totallynot.ai's answer
Unlike Epocrates, UpToDate, or MDCalc, totallynot.ai doesn't look like a clinical tool at all. Epocrates has a recognizable medical icon. UpToDate has a branded header. MDCalc has visible calculators. totallynot.ai looks like someone taking notes in a plain text editor — no visible AI branding, no search bar, no medical app appearance. It's faster to use (just type and get an answer), has no ads, and is $10/month after 10 free lookups with no credit card required.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.

totallynot.ai's answer
Medical students, PA students, residents, nurses, NPs, PAs, and physicians — anyone who needs fast clinical answers at the point of care. Specifically designed for clinicians who need to look something up discreetly in front of patients or attendings without it being obvious they're using an AI or medical reference app.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
totallynot.ai's answer
totallynot.ai was built to solve a very specific problem: looking up clinical information at the bedside without it being obvious to patients or attending physicians. Clinicians often hesitate to pull out their phones and open Epocrates or search Google because it looks unprofessional or makes patients anxious. totallynot.ai solves this by providing an interface that looks like a plain notepad — so you can get fast, accurate clinical answers while appearing to simply take notes.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
