About

LockIn is a focus-first Chrome extension designed to help you study on YouTube without distractions.

When you open YouTube to learn something, it’s easy to get pulled into music, shorts, or random recommendations. LockIn solves this by intelligently filtering content so you can stay focused.

What LockIn does:
• Allows only study-related and educational YouTube videos
• Blocks entertainment, music, and distracting content
• Offers three focus modes: Strict, Normal, and Lenient
• Blocks YouTube Shorts (optional)
• Supports Whitelist and Blocklist for full control
• Works fully offline
• No ads, no tracking, no data collection

LockIn runs entirely on your device and never sends your data anywhere.

Built for students, developers, exam aspirants, and anyone who wants to use YouTube as a learning tool — without losing focus.
