I’m a developer who watches (and learns from) a lot of YouTube playlists — courses, tutorials, lectures, even music mixes. And I kept hitting the same friction: before starting a playlist, I just wanted one simple answer — “How long will this take?” YouTube doesn’t show total playlist duration upfront, so planning becomes guesswork.

So I built ytplaylistlength.one. It’s a small, focused tool: paste a playlist URL (or a video URL / playlist ID), click calculate, and you’ll get the total duration — plus the “real” watch time at different playback speeds (1.25x, 1.5x, 1.75x, 2x, or custom). You can also calculate only part of a playlist (e.g., videos 1–50 or 31–100), paste multiple links, and export the results to Excel if you want to plan or track things.

Two values mattered to me while building it: • Privacy first: I don’t store your URLs or track your viewing habits — inputs are processed and discarded. • Free + no signup: the core tool should stay accessible and frictionless.

If it’s useful, awesome — that’s the whole point. If you notice bugs or have feature ideas, I’d honestly love the feedback.
