“Oblex stands out from the other tools we've trialled — it's the first where every output points back to a source we can defend in review.”
“Lattice has really helped shift our focus from gathering evidence to actually evaluating it. The team spends its time on judgement now, not retrieval.”
“What surprised us was how quickly the team came to trust it. Within a fortnight it was part of how we plan a testing area, not a side experiment.”
