It was intended to be an alternative to wwwxxyy and Ryumaster's Trainer escape glitch yield image and uses Trainer data from the Pokémon Red disassembly project.
This tool provides a drop-down box where the user can select a Pokémon. After choosing a Pokémon, the tool will create a list of valid Trainers and their Pokémon which will cause the glitch to result in the Pokémon chosen from the drop-down box if it was the last Pokémon encountered.
It is currently hosted on the website Exocron.me.
