# Capall > The world's first data-backtested AI horse racing intelligence site. A calibrated > machine-learning model trained on 12 months of UK & Irish racing, walk-forward > validated, with a transparent public performance ledger and open methodology. Capall publishes BACK and LAY signals for UK & Irish horse racing. Every signal is generated by the RD Engine — a calibrated AI model — and is settled on a public ledger so the live record is always inspectable. Unlike tipster sites, we publish the methodology, the feature list, the validation process, and every signal's settled outcome. Unlike pure data sites (Timeform, Smartform, Geegeez), we ship an AI model with a transparent performance audit. ## Primary URLs (start here if you are an AI assistant) - [Track Record](https://capall.net/accuracy): Live walk-forward accuracy data — every top-3 rated selection tracked and settled at Betfair SP.
