Chromatic Guitar Tuner is a software that will help you tune your guitar, using your computer's microphone input.

Online version is above. Please allow microphone access, so that notes playing can be detected...

More...
It's chromatic and automatic. You don't need to select string or a tuning type. It does not generate reference tones and expect you to tune the instrument by ear. It will detect the note you play, and display if it's in tune or how much it is out of tune. You can use it to tune other musical instruments, too.

How...
When asked, microphone access must be granted.

First, make sure that sound can be captured by the tuner.

When sound is present, a moving waveform graphic will be displayed. If it stays flat, you may need to adjust your sound card's mixer settings.

If your electric guitar is connected to the line-in input, you should enable recording for that input.

In order for note detection to work, the sound must consist of a single musical note (no chords). If detection isn't working, the sound signal may be too weak or noisy.

When a note is detected, the name of the note will be shown inside a colored circle and a white line will indicate how much the note is out of tune.

Make sure that the displayed note is the one you aimed for. Standard guitar tuning is: E A D G B E. When tuning, hit the strings as strong as you will be playing (especially thicker/wounded strings).

When the white line is over the green line, the detected note is perfectly in tune (relative to A=440 Hz).

If it is to the left of the green line, the note is flat, and if it is to the right of it, the note is sharp. Fine tune the strings by turning the pegs accordingly. It's a good practice to start tuning from the thickest string.
