Sentence-Level Referencing · New Capability

Every sentence.
Every source. Verified.

The first AI capability to eliminate hallucination at the point of scientific content creation — purpose-built for pharmaceutical Medical Affairs.

Every sentence · Every source · Verified before output
Treatment X demonstrated a statistically significant reduction in relapse rate at 24 weeks[1], with a safety profile consistent across all studied subgroups[2]. Mechanism of action is mediated through selective receptor inhibition[3].
The Problem

The hallucination problem is documented, measured, and severe.

Peer-reviewed research has established that generic AI poses a systemic accuracy risk to medical communications that is both measurable and severe.

69%

of references generated by ChatGPT for medical questions are completely fabricated (Cureus, 2023)

"

18%

of AI-generated clinical documents contain harmful inaccuracies (JAMA Network Open, 2024)

83%

of cases where LLMs amplify planted errors in source material (Nature Communications Medicine, 2025)

How It Works

Built into the generation engine. Not bolted on.

Sentence-level Referencing operates at two levels simultaneously — before any content is delivered.

01 / 02Source Traceability

Sentence-level source traceability.

Every sentence in every VarsaAI output is linked to the specific source document from which its scientific content is drawn. MSLs, medical writers and reviewers see — for every claim — exactly where it came from. Not after review. At the point of creation.

02 / 02Verified References

Verified references only.

Every reference generated by VarsaAI is verified against real, indexed publications before output is produced. No invented PMIDs. No fabricated author combinations. No titles that sound right but don't exist. If a source cannot be verified, it is not included.

"Generic AI was not designed for environments where a single inaccurate sentence carries regulatory, clinical and reputational consequences. Sentence-level Referencing closes that gap. Every sentence has a source. Every source is verified. That is not a feature — it is the foundation that scientific content demands."

For Your Team

What this means in practice.

For medical writers

Create at pace without introducing risk. Every claim you produce is traceable. Every reference is real.

For MSLs

Take scientific content into HCP conversations with confidence. Know exactly where every statement originates.

For review teams

Open a VarsaAI document and see the source for every sentence before your review begins. Stop fact-checking. Start reviewing.

For Medical Affairs leadership

Deploy AI across your content workflows without accepting the accuracy liability that generic AI demands.
