Transparent, retrieval-first expert research workflows

Main watchouts

  • · Retrieval internals and grounding behavior are not strongly documented
Open questions
  • · How citations and abstention behave in production needs testing
  • · Source refresh and segmentation controls require hands-on validation

Methodology: This score evaluates how well a vendor appears to retrieve, ground, and manage knowledge in real-world use. It is not a measure of the vendor's overall product quality. Scores are based on documented capabilities and, where available, hands-on testing. Confidence reflects how much evidence was directly verified.
