KeySim

Mythic+ group optimization for WoW Retail
Companion addon for https://keysim.app

KeySim is a WoW addon and web app that helps Group Finder leaders build the strongest available Mythic+ group.

Instead of simply choosing the applicants with the highest Raider.IO score, KeySim evaluates the entire five-player composition. Its trained model compares the available groups and recommends the combination with the best overall fit for your dungeon and key level.

A lower-scored applicant may be recommended when they improve the group through better role balance, class synergy, utility, gear, or experience.

How it works

List your Mythic+ group and wait for applicants.
Click the KeySim button next to Refresh.
Copy the generated code into https://keysim.app.
Review the recommended composition.
Copy the invite plan back into WoW.
Invite each recommended application using the KeySim Invite Plan window.

Privacy

It does not collect combat logs, chat, account details, or private data. Nothing is sent automatically—you manually copy and paste the export.
