How are claims checked against source evidence?
How the guardrail works
Each uploaded document is chunked with an immutable identifier, then claims are evaluated as supported, partially supported, unsupported, or contradicted.
Evidence controls
Evidence-backed PowerPoint protects the claims that matter in the room.
The workflow makes the citation state visible before a deck reaches export, then produces editable native PowerPoint content.
What happens to unsupported numbers?
How the guardrail works
Unsupported quantitative claims are blocked from export, and contradicted claims hard-block the deck until they are resolved.
Is the exported deck editable?
How the guardrail works
Yes. PurposefulDeck exports native PowerPoint shapes, text, tables, and charts backed by embedded Excel workbooks instead of screenshots.
