AiMod is a modding tool built into the Beatmap Editor. To open AiMod, press Control + Shift + A or navigate via menu options File » Open AiMod once a beatmap is open in the Beatmap Editor.

AiMod aims to help beginner mappers "mod" their beatmaps. The limitation of AiMod lies with its basic design which causes it to sometimes overlook issues such as bad mapping patterns, BPM, or timing. Finding a modder to mod your beatmap is strongly recommended.

AiModAiMod is usually your first modder

AiMod typically completes its beatmap analysis in under a minute and subsequently displays warnings and errors. If no problems were found in your beatmap, then congratulations! The beatmap passed the AiMod analysis, but it still requires modding from the community. The modders can find other issues that AiMod failed to detect.

Tabs

All

  • Gathers the items from the other tabs.

Compose

  • These problems are generally the problem of object placement.
    • You may need to check the "Check distance snap" box for these warnings to appear (as these checks could cause lag, depending on beatmap size/length)

Design

  • These problems are generally some of the interface issues, such as the background, storyboards, etc.

Timing

  • When these problems appear, check the timeline because something is probably placed incorrectly.

Meta

  • When these problems appear, check out the song setup.

Mapset

  • These problems affect the mapset as a whole.

This slider moves in an abnormal way.
This combo is very long. Consider splitting it up. The length of combos can affect the difficulty of the map, as well as the amount of fruits that will be stacked on the catcher's plate. Go to the offending combos and decide where to start the new combo. (It is prefered that length of combos are, at most, 15-18)
This spinner appears onscreen later than objects which follow it. Objects appear while the spinner is active. This could be caused by having low AR and/or placing objects too close (time-wise) to the spinner. Change the length of the spinner and/or remove the following objects
Object's end is offscreen! Objects that are offscreen may not be seen in osu!clients running in 4:3 ratios. Remove or move the object's end
