For viewers

Paste a playlist or the video you stopped on to see the full length, any stretch of it, and the time left at 1× to 2×, with watched marks kept on your device.

Drop your Google Takeout export and see which channels you came back to on the most days, when in the week you open YouTube, which videos you opened again and what changed from the previous year. The file is read in your browser and never uploaded.

Find out how many years of your life have gone into YouTube. Enter when you started and your daily average, and see the total in days, films, work weeks and nights of sleep — plus what a smaller daily habit would give back.

See how many GB YouTube burns at each quality, what it costs on your plan, and the highest resolution your remaining data can actually afford.

See exactly when you’ll finish a YouTube course or playlist — set your playback speed, daily time, and weekly schedule (or work backward from a deadline) to get a real finish date, not a guess.

See how many days of your life your own YouTube habit gives to ads — based on your viewing time and ad behavior, not platform averages.

See if YouTube Premium pays for itself based on your own viewing habits, device, and music subscription — not a generic 2-hour rule.
