YouTube Playlist Analyzer 作成者: SomeOne

YouTube Playlist Analyzer enhances your YouTube experience by automatically displaying the total duration and video count of any playlist you visit. No more manually checking each video or guessing the total runtime — the extension adds clear, accurate information directly within the YouTube interface.

This extension is lightweight, privacy-focused, and designed to blend seamlessly with YouTube’s layout. It runs quietly in the background, activates only on playlist pages, and never collects or stores personal data.

Features

📌 Instant total duration
Displays the full playlist runtime in hours, minutes, and seconds.

📌 Accurate video count
Shows how many videos the playlist contains, including long playlists.

📌 Native YouTube look
Integrates naturally into YouTube’s UI without altering the page design.

📌 Fast and efficient
Only triggers on playlist pages and uses a lightweight API for calculations.

📌 Privacy first
Does not collect browsing history, account data, or any personal information.

How it works

When you open a YouTube playlist, the extension:

Reads the playlist ID from the page.

Sends a request to a secure API to fetch total duration and count.

Injects the result into the YouTube page in a clean, readable format.

No data leaves your browser except the playlist ID, and no identifying information is collected or stored.

Privacy

This extension:

Does not collect IP addresses

Does not access or store personal data

Does not read cookies or account information

Does not track browsing behavior

Only public playlist metadata is used.

Open Source

The extension logic is straightforward and transparent. You’re welcome to review, audit, or contribute to the project.

Why this extension exists

Long playlists can be hard to evaluate. Whether you're studying from tutorials, planning watch-time, or managing content, knowing the total duration upfront saves time and effort. YouTube doesn’t provide this by default — so this extension fills that gap cleanly.
