# The Co-Creation Model

> The co-creation model is the design philosophy in which AI arms the medical writer instead of replacing them — automating the ledger work (evidence links, annotation, drift checks, pre-review) while the human keeps every judgment.

> The **co-creation model** is the opposing design philosophy to [one-button authoring](/perspectives/one-button-authoring/): AI as the medical writer's instrument, not their replacement. The division of labor is drawn along judgment: the machine does the *ledger work* — finding substantiating passages, maintaining claim–evidence links, generating annotations, detecting drift, pre-running review checks — while the writer keeps every decision about what to say, to whom, and whether it can be defended.

The model rests on a claim about the nature of intelligence work generally: the deliverable is the residue of thousands of judgments, and the judgments — not the typing — are what clients, reviewers, and regulators are actually paying for. Automating the typing while keeping the judgment makes the expert faster. Automating the judgment while keeping a human to click "approve" produces [human-as-the-loop](/perspectives/human-as-the-loop/) — the model's degenerate twin.

In practice, co-creation tooling has a recognizable shape: it lives where the writer lives (Word, PowerPoint — not a separate portal); it treats claims and evidence as first-class linked objects; it is *sourced-only* (it cannot cite what isn't in the references — nothing is generated into the evidence layer); and its speed shows up as fewer review rounds rather than more drafts. This is the shape we built [Claims](/) in, working with medical writers with decades in the craft — which is also our disclosure: we are partisans of this model, not neutral observers of it.

The strategic case for co-creation over automation in regulated industries reduces to one line: **when generation becomes free, verification becomes the product** — see [the verification asymmetry](/perspectives/verification-asymmetry/).
