PreChart is a pre-charting verification agent for the office visit. It drafts a specialty-styled clinical note from the chart and the ambient conversation, and — where the two disagree — it doesn't just pick a side. Its founding assumption is what makes it different: the chart and the conversation are two fallible witnesses (charts go stale and carry copy-forward/coding errors; patients misremember, use lay terms, and get mis-transcribed), so PreChart trusts neither by default. For each claim it gathers adjacent, objective evidence, proposes which account the evidence supports, and surfaces the conflict for the clinician. The clinician can accept the agent's call or select the truth themselves — and the note updates live to match. Nothing high-stakes is auto-written; the clinician signs off.
