YieldStack's answer
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
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.
YieldStack's answer
YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.
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.
YieldStack's answer
Commercial real estate investors, developers, operators, and mortgage brokers seeking bridge, DSCR, fix-and-flip, construction, multifamily, and permanent financing across the United States.
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.
YieldStack's answer
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
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.
