Comparison
Knowledge Company vs Grounding Infrastructure
Hallucination detection and grounding evaluation, scoring whether a generated sentence is supported by a retrieved passage.
In short
Grounding models score whether a sentence is supported by the passage retrieved, with no opinion on whether that passage is correct. They are infrastructure we build on: if verification is free, the value is entirely in the record being verified against.
The four coordinates
Every company in this landscape can be located by four questions. Applied consistently, the apparent crowding resolves into something much narrower.
Ground truth
What fires it
What it writes to
Who buys it
What they do
Patronus Lynx scores sentence-level grounding against a context passage and ships as open weights. Galileo Luna runs groundedness through Evaluate and Protect. Arize Phoenix offers OpenTelemetry-native tracing with RAG evaluation templates.
These are foundational tools, and several are free.
How we differ
These are suppliers rather than competitors, and they make our argument for us. Sentence-level claim grounding is already available as an open-weights model at no cost, which means the checking primitive cannot be anyone's moat.
What they ground against is whatever passage was retrieved; they have no opinion on whether that passage is correct. If verification is free, the value is entirely in the record being verified against — which is the thing Knowledge Company maintains.
Which one you want
Choose them if
You are building an AI system and need to evaluate whether generations are grounded in retrieved context.
Choose Knowledge Company if
You need the retrieved context itself to be correct and current.
