Morse Code
Type something and hear it as sound and light, the way it would actually go out. Save it as an image, key it in by hand, or learn to read it by ear. It all runs in your browser: whatever you type stays on your machine.

0Spacing below speed is the Farnsworth trick: the characters stay fast, the gaps between them get longer. It is how people actually learn, because you cannot slow a character down without learning the wrong rhythm.
Characters arrive in Koch order, not alphabetical: the hardest pair first, then one more each time you hold 90% over 20 answers. Progress is saved in this browser only.
What you keyed
Decoded
·The timing adapts to you: whatever your fastest taps are becomes the dot length, and anything roughly three times longer is read as a dash. So it does not matter how fast you key, only that you are consistent.
