# Prompt tracking across answer engines

> Tracks a set of prompts over time across several answer engines, so a change in what they say is visible rather than anecdotal.

## Key facts

- **Why several engines:** One model's answer is one model's opinion. Share of voice is only comparable when the same prompts go to each engine.
- **Disclosure:** Where an engine answers only part of a run, the report states how many of the run's prompts it was actually sent, rather than printing a smaller number with no explanation.
