How does a capo change chord names?

A capo clamps across all strings at a given fret, raising the open string pitch by one semitone per fret. So a G chord shape with a capo on fret 2 sounds like an A chord, because 2 semitones above G is A.

What is the difference between the "tab chord" and the "sounding chord"?

The tab chord (or "shape") is what your fingers play — the chord name written in the guitar tab. The sounding chord is the actual pitch that comes out of the guitar with the capo in place. Listeners and other instruments hear the sounding chord.

Can I use this to find the chord shape for a sounding chord?

Yes. Switch the direction to "Sounding chord → Tab shape". Enter the chord you want to sound and the capo fret, and the tool tells you which chord shape to finger on the fretboard.

Does the tool support sharps and flats?

Yes. You can toggle between sharp (e.g. F#) and flat (e.g. Gb) notation. Both names refer to the same pitch — choose whichever matches the key you are working in.

Why would a guitarist use a capo instead of just playing barre chords?

A capo lets you use easier open chord shapes while playing in keys that would otherwise require barre chords. It also produces the bright, resonant tone of open strings, which barre chords cannot replicate.

What happens at capo fret 12?

Fret 12 is one full octave higher, so the chord names are the same as no capo. A C chord with capo 12 still sounds like C, just one octave up. In practice, frets 1–7 are the most commonly used capo positions.
