  description

  Your YouTube Watch Later list is full of videos you meant to watch. Most of them you never will — not because you don't want to, but because you never set aside the time.
  
  Zman fixes that.
  
  Zman adds a "Schedule to Watch" button to every YouTube video. Click it, pick a date and time, and Zman blocks the exact video duration in your calendar. A 2-hour documentary on Friday night. A 45-minute tutorial on Saturday morning. Done.
  
  What Zman does:
  — Adds a "Schedule to Watch" button to every YouTube video
  — Auto-fills the exact video duration so your end time is calculated for you
  — Sends the event to Google Calendar, or downloads an .ics file for Apple Calendar and Outlook
  — Supports multiple Google accounts — choose which calendar to add it to
  — Add personal notes to your calendar event (what to look out for, who to share it with)
  — Works on live stream replays with real durations
  — Dark mode and light mode aware — looks right on any YouTube theme
  
  Who it's for:
  Anyone who watches YouTube with intention — learners, researchers, content creators, and anyone who has ever said "I'll watch this later" and meant it.
  
  Privacy:
  Zman collects no personal data. Nothing is sent to any server. Everything stays in your browser.
  
  How to use:
  
  Open any YouTube video
  Click "Schedule to Watch" next to the Like and Share buttons
  Pick your date and time
  Add to Google Calendar or download .ics for Apple Calendar / Outlook
  Your time is worth protecting. Zman helps you protect it.

  Zman fixes that.
  
  Zman adds a "Schedule to Watch" button to every YouTube video. Click it, pick a date and time, and Zman blocks the exact video duration in your calendar. A 2-hour documentary on Friday night. A 48-minute tutorial on Saturday morning. Done.
  
  How to use it:
  Open any YouTube video
  Click "Schedule to Watch" — sits right next to Like and Share
  Not sure when you're free? Hit "Find a time slot" to check your Google Calendar, then come back and drop the time in.
  Pick your date and start time — Zman calculates your end time automatically
  Click "Add to Google Calendar" — or download .ics for Apple Calendar or Outlook
  
  That's it. The video is in your calendar, the time is blocked, and you'll actually watch it.
  
  Who it's for:
  Anyone who watches YouTube with intention — learners, researchers, content creators, and anyone who has ever said "I'll watch this later" and meant it.
  
  Good to know:
