Slow Downer & Loop Trainer
Upload a recording or paste a YouTube link. Slow it down without changing pitch, and loop the two bars that are actually the problem.

Most practice time leaks away replaying music you can already play. Set the A marker just before the passage that breaks down and the B marker just after it, then let it cycle at 70% speed while you play along. The loop removes the temptation to 'take it from the top.'
Pitch-preserved slow-down, in the browser
Uploaded audio uses your browser's built-in time-stretching, which keeps pitch constant while the tempo drops — no software to install. YouTube playback uses YouTube's own pitch-preserving speed control. Both are free without an account.
