One bit of complexity that lots of tools like this seem to always punt on is the fact that most chords (at least in jazz) are typically played rootless and inverted and with lots of 'upper extensions'. It would be nice if a tool really did a deep dive in actual chord voicings that one would play in the real world (i.e. in a context where the bass player is covering the root and therefore it is best left out of the chord).

As an example of something that is very systematic (easy to put in an app), a rootless C maj 7 is equivalent to an E min 7. A rootless C min 7 is equivalent to an Eb maj 7. etc.

It is a pretty tough leap to learn rootless jazz piano comping when almost everything out there (except for the old-school dead tree books) only ever shows rooted voicings.

> a rootless C maj 7 is equivalent to an E min 7.

You mean just the regular E minor (triad)?

Anyway, there'a quite a lot of stuff on this site apart from this cheat sheet page: the chord page does indeed include inversions, e.g.: https://muted.io/c-major-chord/

Jazz sheets often write 7 assuming it may be played as 9, if not 11/13 even. A triad in the left hand being a bit too pedestrian, a rootless “Cmaj7” is virtually always played as a rootless Cmaj9 (EGBD), or more commonly a rootless C69 (EGAD) especially if the tonic. Inversions may include the root instead of a 9th, e.g. BCEG.
