Auto (AT) mod icon
Watch a perfect automated play through the song.
Notice: Enabling the Auto mod will cause the play to be unranked and will not be saved to the local leaderboards.
The Auto mod is a game modifier that allows players to watch a perfect playthrough of the selected beatmap.
The mod functions exactly like a replay, with the options for 0.5x/1.0x/2.0x speed playback to be used and comments on the beatmap to be seen and made like normal. The Auto mod will always get an SS grade, with the exception of a few special cases.
In osu!, when encountered with a spinner, the Auto mod will spin to a maximum of 477 spins per minute (SPM) in a anticlockwise rotation.
In osu!taiko, the Auto mod will attempt a perfect playthrough, but won't always get an SS grade. It will occasionally miss a tick on drum rolls that do not start on a whole or half beat and will not always be able to complete dendens on maps with a very high overall difficulty.
In osu!catch, the Auto mod will actually go beyond perfect and use unlimited speed to catch every single banana in a spinner, despite such a feat being impossible for a human player.
In osu!mania, the Auto mod will attempt a perfect playthrough, but may miss objects in the same column that are overlapping or placed within 1 ms of each other.
