The Glass Box Difference

Our AI Writer Agent cannot

access the open internet

Unlike ChatGPT or general-purpose Al tools, our Writer agent can only synthesize evidence that has already been found, verified, and curated by upstream agents. That's how we establish provenance.

THE CRITICAL CONSTRAINT

The Writer Agent is forbidden from accessing the internet. It can only synthesize evidence that has already been verified by the upstream agents.

Every output is grounded in curated, ranked, verified evidence — not generated from thin air.

1

The Architect

"What do we need to prove?"

Analyzes the OSW (Objective, Scope, Watchouts) and breaks down high-level objectives into specific, verifiable hypotheses. Translates business questions into scientific claims that can be tested against evidence.

RECEIVES

OSW Document, Strategic Context

PASSES FORWARD

Candidate Statements, Key Intelligence Questions

2

The Researcher

"Find everything on this topic."

Executes comprehensive searches across academic databases, clinical trial registries, and regulatory sources. Builds the raw Search Index that contains every potentially relevant source.

RECEIVES

Candidate Statements, Search Parameters

PASSES FORWARD

Raw Search Index (DOIs, PMIDs, NCT IDs)

CONSTRAINT

Can only search sources defined in scope. Cannot modify the hypotheses.

3

The Auditor

"Does this source prove the claim?"

Reads source documents and evaluates whether they actually support the candidate statements. Applies PICO structuring to ensure precise matching. Assigns verification status.

RECEIVES

Candidate Statements, Raw Search Index

PASSES FORWARD

Statement–Evidence Mappings, Verification Status

CONSTRAINT

Can only read sources in the Index. Cannot search for new sources.

4

The Curator

"Is this evidence strong enough?"

Applies evidence hierarchy rules to filter and prioritize sources. Ensures the final Evidence Library contains only high-quality, relevant citations.

RECEIVES

Statement–Evidence Mappings, Hierarchy Rules

PASSES FORWARD

Curated Evidence Library

CONSTRAINT

Cannot override Auditor verification status. Can only rank and filter.

5

The Writer

"Synthesize the verified facts."

Assembles the final narrative from verified evidence. Applies language neutralization. Generates the AI Narrative Report with complete traceability.

RECEIVES

Curated Evidence Library, Document Structure

PASSES FORWARD

AI Narrative Report, Reasoning Trace

CONSTRAINT

Cannot access the internet. Can only use evidence from the Curator's Library.

Your team starts writing with an 8 week head start

Traditional document development requires weeks of foundational work before narrative development begins. We compress that into days.

How It Works

Three integrated components
One verified foundation

Each Acceleration Package delivers the rigorous scientific synthesis, verified evidence, and comprehensive traceability your team needs to move directly to narrative development.

Al Narrative Foundation

Rigorous scientific synthesis

Coverage of all dimensions in agreed scope

Every claim linked to supporting evidence

Neutralized, verifiable scientific language

Ready for your writers to shape the story

Reasoning Trace Report

Full transparency into decisions

Verification rationale for each statement

Evidence conflicts documented and explained

Audit trail supporting MLR review

How and why conclusions were reached

Evidence Libraries

Curated, searchable collections

Citations with DOls and links

Evidence hierarchy labels (RCT, Meta-Analysis, etc.)

PICO extraction for clinical evidence

Bi-directional mapping to statements

Strategic Memory

Scoping that captures

what matters

We replace vague briefings with the OSW Framework: Objective, Scope, Watchouts. This ensures alignment on goals without over-constraining the deliverable.

O
Objective
What does success look like? What question are we answering?
Example: Develop the scientific foundation for an SCP establishing Drug X as the preferred first-line treatment in moderate-to-severe RA.
S
Scope
What's explicitly included and excluded. Clear boundaries prevent drift.
Example: Include: All Phase III data, real-worid evidence post-2020, JAK inhibitor class comparators. Exclude: Pediatric populations, biosimilar considerations.
W
Watchout
Off-label sensitivities. Class effects to avoid. These become system constraints.
Example: Avoid generalizing cardiovascular class effects without study-specific attribution. Do not reference off-label use in lupus.
