LLM extraction is fast.
Trust is the bottleneck.

Your model extracts data in seconds. But your users still ask: "Where did that come from?"

01

Confident mistakes happen

LLMs return plausible values that aren't in the document. No warning, no uncertainty flag.

02

Manual verification kills ROI

Hunting through a 50-page PDF to find one value doesn't scale.

03

Auditors need provenance

"The AI said so" isn't defensible in regulated workflows.

04

Adoption depends on proof

When users can verify in one click, they trust and use the tool.

📄

LLM hallucinations aren't going away, researchers have proven they're structurally inevitable. That's why verification matters. See the paper →

The Missing Layer

There's a gap between what LLMs output and what your users can trust. The solution? A verification layer that connects every extracted value back to its source, instantly and verifiably.

CiteLLM is the missing layer between model output and human trust.
