SubShelf — Smart YouTube Subscription Folders

Transform your cluttered YouTube subscription feed into organized, themed category folders. Are you subscribed to 50, 100, or 500+ channels and tired of endless scrolling? SubShelf brings native-feeling category folders directly into your YouTube™ left sidebar and subscription feed. SubShelf is free, lightweight and privacy-first: no paywalls, no account, and no tracking. KEY FEATURES: • Smart Category Folders: Group channels into folders (Tech & Coding, Gaming, Music & Audio, Education & Science, Finance & Business, News & Politics and more, or your own) right inside YouTube's sidebar. • 1-Click Auto-Sort: Sorts all your subscriptions into folders in seconds, fully offline, using channel names and descriptions. Optionally uses Chrome's built-in on-device AI (only if Chrome already has it; SubShelf never downloads AI models) or Google Gemini with your own API key. • Learns From You: Every channel you move or drag teaches its folder, so similar channels follow on the next Auto-sort, including into folders you created. • Custom Feed Filtering: Click a folder to see only videos from its channels on your Subscriptions feed. More videos load automatically without moving your scroll position. • Folder Chips: Switch between folders from a chip bar above your Subscriptions feed (All · Tech · Gaming …). • Drag & Drop: Move channels between folders, or drag them straight from YouTube's own subscription list. • In-Sidebar Controls: Add channels with a searchable picker, remove channels (✕), and rename or delete folders from each folder's ⋯ menu, without leaving YouTube. • Safe Subscription Sync: New subscriptions are added and sorted automatically. Unsubscribed channels are removed only after repeated complete checks, so a partly loaded page can never wipe your folders. Channel avatars are filled in from YouTube. • Full Popup Manager: Search any channel, move it to another folder, and create, rename or delete folders from the extension popup. • Hide Shorts: One toggle removes the Shorts shelf and Shorts videos from your Subscriptions feed. • Private & Local: Your folders and settings are stored locally in your browser. No tracking, no ads, and no SubShelf servers. • Backup & Restore: Export and import your folders as a JSON file to move your setup to another computer (your API key is never included). PRIVACY & PERMISSIONS: SubShelf asks only for what it needs: • Storage: Saves your folders, channel assignments and settings locally on your device. • Offscreen: Used only to run Chrome's on-device AI in a hidden extension page if you turn it on. It runs entirely on your device and never downloads a model. • Host permission (https://www.youtube.com/*): Shows the folder sidebar and filters the Subscriptions feed on YouTube. SubShelf runs on no other site. • Optional host permission (https://generativelanguage.googleapis.com/*): Not granted at install. Chrome asks for it only if you choose Google Gemini Cloud with your own API key. Channel names, handles and short descriptions are then sent to Google using your key.
