How Does Mary Ensure The Accuracy Of The Generated Chronologies? Because our software operates on a closed data source (i.e., only your client documents that you provide), there is very little risk of hallucination. All answers are purely grounded in the documents you provide. Mary uses a multi-stage AI processing system to verify and cross-check the extracted information against the source documents. This process ensures that the generated chronologies maintain a high level of accuracy, achieving over 99% pre-review precision.
