Chartproof

A verification layer for physicians who use AI on clinical notes under their own license

A tool for independent physicians who already draft notes and letters with AI: it checks model output against the chart facts the doctor loaded, flags unsupported clinical statements, and keeps a record of what the AI suggested versus what the physician signed.

Test it before you build it

$500 · 4 weeks · 20 prospects

For $500 and four weeks, prove that independent physicians will pay $149 a month for a standalone chart-verification layer instead of waiting for their scribe vendor to add the check.

Riskiest assumption · An independent physician who drafts notes with AI will pay $149 a month for a separate verification layer under their own license rather than waiting for their ambient-scribe vendor to bundle the check.

1Focus group: who and where

A physician-owner of a direct primary care or concierge practice with 1-3 clinicians and no hospital IT, already drafting visit notes, referral letters or appeal letters with ChatGPT, Claude or an ambient scribe, and personally liable for every unsupported statement they sign.

where to find 20 · The DPC Docs Facebook group and DPC Alliance membership, where DPC owners compare tools daily (community); the public DPC Frontier Mapper listing 2,000+ US DPC practices with websites and owner emails (directory); Doximity DMs to independent physicians who post about AI documentation (channel).

2Sell first, build later

Every AI-drafted clinical claim checked against the chart facts before you sign, plus a record of what the model suggested versus what you approved - sold now as a 10-note manual verification pilot for $149, converting to self-serve software when the founding cohort onboards December 1, 2026.

the ask · $149 prepaid for the 10-note pilot now; $149 per month founding subscription locked for 12 months

a real yes · A real yes is a $149 card charge with de-identified notes attached or a cleared first-month prepay with an onboarding date; 'my scribe should do this,' unpaid pilot requests, and enthusiastic demo feedback count as no.

3Small experiments

The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.

  1. 1. Twelve DPC physician calls

    $150 · 10 days

    Email 40 practice owners from the DPC Frontier Mapper - in DPC the physician answers their own inbox - and DM matching physicians on Doximity, offering a free claim-by-claim grading of one de-identified note as the hook. On each 20-minute call, walk their last AI-drafted note: what the model added, how they caught unsupported statements before signing, and what record exists of AI involvement. End by offering the paid pilot in experiment 2.

    keep going if · 8 of 12 calls confirm they draft with AI and re-verify against the chart by hand or not at all, and 6 of 12 agree to a paid verification pilot

  2. 2. Paid manual note verification

    $150 · 14 days

    The physician sends 10 de-identified visit notes plus the chart facts behind each (problem list, meds, labs); the founder returns every clinical claim graded chart-supported, unsupported, or needs-review within 24 hours per note, for $149 prepaid - one month's price for two weeks of proof. Offered to all 20 prospects on calls and by follow-up email; the founder grades every note personally.

    keep going if · 6 of 20 offered prepay the $149 and send notes

  3. 3. Founding cohort prepay

    $200 · 14 days

    Launch a one-page site: $149 a month locked for a year, 15 founding slots, onboarding December 1, 2026, with the physician's own note templates loaded first. The buy button collects the first month up front - credible because DPC owners already buy Hint, Elation and Spruce self-serve by card with no procurement. Pitch at the end of every call and in one follow-up email.

    keep going if · 5 of 20 prepay the $149

4Collect a deposit up front

Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.

$149

per prospect, refundable

how · The first month prepaid through the landing page checkout - the right instrument for a buyer who purchases their entire practice stack self-serve by card, with no committee and no procurement; the physician checks out, no signature needed. set up: Stripe Checkout ↗

what it reserves · One of 15 founding slots, the $149 monthly rate locked for 12 months, a December 1, 2026 onboarding date, and their own note templates configured first

refund · Refunded in full, no questions asked, any time before the December 1, 2026 onboarding.

target · 5 first-month prepays from 20 prospects within 30 days

before taking money · Clinical notes are PHI under HIPAA, so accept only de-identified notes and chart facts until a BAA and security review are in place, and store no live patient data anywhere during the test.

Go: build it if

6 of 20 pay $149 for the 10-note pilot and 5 of 20 prepay the first month - at least $1,500 collected from 20 prospects in four weeks.

Kill: stop if

Fewer than 3 paid pilots and fewer than 2 prepays from 20 prospects, or 8+ of 12 calls say they will wait for Freed or their current scribe to add chart-fact checking.

5 Scripts to run itoutreach message, landing copy, deposit terms · click to open

outreach message

You run a DPC practice and draft notes with AI to stay out of the chart at night - and every unsupported line the model adds gets signed under your license. I'm building Chartproof: each AI claim graded against your chart facts before you sign, with a record of what the model wrote versus what you approved. Before I build it, I'll grade 10 of your de-identified notes claim by claim, back within 24 hours each, for $149. Do you have 20 minutes this week?

landing page

deposit terms

Your $149 prepays the first month at the founding rate, locked for 12 months, and holds one of 15 slots onboarding December 1, 2026. It is fully refundable, no questions asked, any time before onboarding. Until a BAA is in place, send de-identified notes only.

The concept in full

What
A tool for independent physicians who already draft notes and letters with AI: it checks model output against the chart facts the doctor loaded, flags unsupported clinical statements, and keeps a record of what the AI suggested versus what the physician signed. In the first hour a doctor connects their note templates, runs one visit note, and sees every claim graded as chart-supported or not.
Grounded in (2025-2026 signals)
MIT NANDA's State of AI in Business 2025 (published August 2025): more than 40% of knowledge workers use personal AI tools at work and call the same models reliable in their own hands, unreliable inside enterprise systems; 'health assistant' first seen 2025, 3 companies in 2025-2026 vs 0 before; Galen AI (yc X25) built a personal AI healthcare agent and its site is down.
What it rides
The GenAI Divide: 95% of pilots return nothing, workers run their own tools. Hospital-sanctioned AI stalls in the 95%, so Chartproof sells directly to the physician in the shadow-AI 40% and gives that personal use a defensible record.
Why now
The August 2025 MIT finding that 95% of enterprise pilots show no return while 40%+ of workers run personal tools describes medicine exactly: institutional AI is stuck in procurement while individual physicians are already pasting notes into chatbots with no verification and no record, and the 3 'health assistant' companies of 2025-2026 all aim at patients, not at the licensed clinician.
Wedge: first customer and entry point
Direct-pay and concierge physicians and small independent practices, who have no hospital IT to wait for and full personal liability. Entry point is one workflow: the AI-drafted visit note, verified against the chart before signature, self-serve at $149 a month.
Closest real companies, as the generator saw them
Novoflow and Pelica sell AI employees and agents to clinics as operations outsourcing; Galen AI (site down) went consumer. Chartproof is the only shape here where the physician keeps doing the work and buys verification and a record, not labor.
Main risk
Ambient-scribe vendors add a chart-fact check to products physicians already use and absorb the category.
