Using it

  1. Sign in with SteamIn the ChemRage window. Without signing in you get the free view: tiles coloured by their base win rate, no recommendations.
  2. Set Dota to borderless windowOn your main monitor: Settings → Video → Display mode. Nothing can draw over exclusive fullscreen.
  3. Press Start capture when the draft startsOr press CtrlShiftS without leaving the game. The overlay appears on its own.
  4. Click your slotThe ring next to your player card tells it which slot is yours, or pick it in the app.

Playing with a friend who is capturing? Paste their party link or code into Join a party in the ChemRage window instead. The overlay then follows your slot on their board; their pass covers you.
