AI for claims work should do the reading, not the judging.
Every document placed, every figure tied to its source. What it means, who is responsible, what is owed: that stays with the person whose name goes on the report.
Every matter in order adds to a connected picture of what happened on a project and what it cost, so your time goes to the opinion.
