Built by a physician who got tired of cosigning notes at 11pm.
CosignMD is the AI layer for the rest of your practice — notes, calls, messages, faxes, prior auth. One login. One system that actually talks to itself. Built during rounds, not in a boardroom.
I'm Alfredo Lee Chang, a pulmonologist and intensivist. For years I thought my problem was the notes — that if I could just finish charting by 11pm, I'd have my life back.
Then one Tuesday I finished a note at 10:45. I still had three voicemails, a fax I never saw, and a prior auth my staff had re-drafted twice. The notes weren't the problem. The notes were just the last thing I did every day, after surviving everything else.
I tried every tool on the market. Each one fixed one thing and ignored the other five. So I built the thing I actually needed — one system where the note, the call, the fax, the message, and the PA all know about each other. Because they're all me.
The rest of your stack, replaced.
Independent physicians run their practice on six separate subscriptions that don't talk to each other. CosignMD is the layer that retires all of them, with one context the AI actually understands.

After · one layer
Three surfaces. One context.
The advantage isn't that it does six things. The advantage is that the AI knows what happened on the other five when you ask about the sixth.
Defensibility catches the queries before they hit your inbox.
Type, etiology, acuity, link to treatment — flagged before you sign. Billing codes suggested with severity and rationale. Not a checklist. A read of your note the way an auditor reads it.
Calls, texts, and faxes that draft their own replies.
Incoming pharmacy call gets AI-transcribed, cross-referenced against today's note, and a draft reply is ready before you check your phone. Patient texts triaged by clinical urgency, not arrival time.
Prior auths drafted from the chart that justified the order.
The PA draft pulls from the note you already wrote. Diagnosis, medical necessity, prior treatments tried — assembled. You review, sign, fax. Built to cut the 30 minutes your staff spends reconstructing context.
If any of these sound like you.
CosignMD is built for a specific kind of clinician. If it fits, you'll feel it in the first session.
- You finish your charts after your kids are in bed.
- You pay for three or more tools that don't talk to each other.
- You've been queried for vague documentation more than once.
- You want your practice data to belong to you — not your hospital.
- You'd rather pay one platform than orchestrate six.

A small group of physicians shaping the next year of the product.
Founding physicians get direct access to the founder, lifetime-locked pricing at $99/mo, and a seat at the table on what gets built next. In exchange, we ask you to actually use it and tell us what's broken.
This isn't a launch funnel. It's a handful of physicians helping shape a platform before it opens to everyone. Spots are limited by how many people one founder can personally support.
Lifetime-locked rate. Direct founder access. A seat at the table on what gets built.
For physicians who join after the founding cohort fills.
Ongoing rate for new subscribers once early access closes.
Your whole practice, one layer.
Built by a physician. Used by physicians. For physicians who'd rather be practicing medicine.
