Siguru checks the copy. VarsaAI proves the AI.
Your teams already write with ChatGPT, Claude and Copilot. Siguru reviews the finished material. VarsaAI verifies every claim the moment AI generates it, with a source behind every sentence.
The short version
Siguru is a promotional review assistant built for UK pharma marketing and medical teams. It checks finished materials against the ABPI Code.
VarsaAI is AI verification infrastructure. It sits inside the AI tools your workforce already uses and checks each claim as it is written. It traces every sentence to its source and logs all of it in one Audit Trail.
One reviews the output. The other makes sure the output can be trusted in the first place.

Seatbelt, not safety net
Every review tool shares one limit. It can only check content after the content exists.
VarsaAI works one step earlier. VeriCore™ verifies scientific claims as the AI writes them. VeriRef™ attaches the exact source to every sentence. An unsupported claim never reaches your reviewers, and nobody has to catch it later.
Fewer flags. Fewer rounds. Faster sign-off, with proof built in.
Cover the AI you can’t see
Your medical, marketing and commercial teams aren’t waiting for an approved workflow. They’re drafting in ChatGPT and Copilot right now.
A review platform only sees what gets submitted to it. VarsaAI runs inside the tools people already use, so every AI-generated claim is verified and traceable, whether or not it is ever submitted for review.
Receipts, not red flags
A flag tells your reviewer to go and look. A receipt shows them the answer.
For every claim, VarsaAI shows the sentence, the source it came from and the verification result. Everything is logged in a full Audit Trail that reviewers, auditors and regulators can follow end to end.
Built for the whole enterprise
Siguru is built for brand and medical teams. VarsaAI is built for the people accountable for AI across the organisation: CISOs, Heads of Information Security and AI Governance leads, alongside Medical Affairs.
- One verification layer across every team and every model
- One dashboard for every claim and every source
- Governed under an ISO/IEC 42001 AI management system programme, the standard built specifically for AI
Where the two overlap
Both platforms help regulated teams get to “right first time” faster, and both keep humans in charge of final sign-off.
If your only goal is code-hygiene checks on UK promotional materials, Siguru is built for that. If you need proof that what your AI produces is true, sourced and traceable across every team, market and tool, that is VarsaAI.
