Hi Product Hunt, I'm Piyush. I built this because I kept starting long YouTube courses without knowing what I was signing up for. YouTube tells you a playlist has 158 videos. It never tells you that's 86 hours. What it does: • Paste a playlist, channel or video link and it adds up every video, up to 5,000. A lot of length tools quietly stop at the first 100: for Corey Schafer's Python series that gives 40 hours instead of 86. • Shows the time at 1.25× to 2×, and turns "an hour a day" into a finish date. • Puts the course in your calendar. Pick your minutes a day and the days you watch, and every study session becomes an event listing that day's videos, in Google Calendar, Apple Calendar or Outlook. Subscribe instead of downloading and the plan keeps up as the playlist grows. The other length tools I've tried stop at a finish date. • Compares up to five courses side by side, before you pick one. • Free extensions for Chrome, Firefox and Edge show the total, and the time left at your speed, on YouTube itself. • A badge and a small free JSON API, if you teach or build things. It's free, with no signup. It runs on Cloudflare Workers' free plan, and I wrote most of the code with Claude Code. Two things I'd love feedback on: what you'd want the plan to do that it doesn't, and any playlist where the total looks wrong.
