Cassiel

Clinical trials made
clear.

Calmly for patients. Precisely for operators. Convincingly for buyers. The platform beneath study authoring, release governance, and multilingual study sites — with the same craft every time.

What Cassiel is

01

Author with governance, not email threads.

Every draft is versioned. Every release is signed. Every change is audit-logged at the edge. Nothing about a clinical study should be ambient.

02

Ship in every locale your protocol touches.

Paraglide-typed translations, per-locale stale-vs-source governance, and first-class fallbacks. de-DE is a floor, not a feature request.

03

Operate by hand, by CLI, or by agent.

MCP, REST, CLI, and Studio UI are transport layers over the same governed operations. A sixty-study agency scripts what a one-study author would click.

The promise

The design system is the same discipline on every surface — the patient's calm study site, the operator's quiet studio, the buyer's editorial marketing site. Restraint is the premium signal. Clarity is an act of care.
