What it decides

The decision, and the evidence it returns

Every call returns the outcome, a certainty factor, a fact identifier and the full evidence tree: the rules that fired, the facts they used and the reasoning that joined them. Backward chaining means the reasoning engine only asks for the data it needs.

Rainbird accelerators produce precise, deterministic and fully auditable decisions without calling an LLM for judgement, and each one can be pivoted to your policy and integrated over API or MCP.

Inside the Accelerator

What's inside, and how it's proven

Two modes serve both sides of the same claim. Insurer mode takes an incoming credit hire pack and adjudicates it end to end: subscriber status, vehicle group equivalence against a 971-model reference table, the maximum daily rate by hire period across all six published rate eras back to 2014, need and impecuniosity, duration reasonableness, storage and recovery, and an itemised settlement figure with the reasoning behind every abatement. It returns exactly one of six outcomes, and CHO mode runs the same law before submission so the pack goes in clean.
