Bulk copy/move videos across playlists with checkboxes. Export/import playlists as JSON. The missing YouTube power-user tool.
Free Tampermonkey / Violentmonkey userscript. Bulk copy or move videos across your YouTube playlists using checkboxes. Export and import playlists as JSON. The missing YouTube power-user tool.
PlaylistPlus.user.js and click Install, or paste the contents into a new userscript.Browse to any playlist page on YouTube: /playlist?list=..., /feed/liked, or a /watch?list=... page. A small red P badge appears in the bottom-right corner. Click it to expand the panel.
The panel header shows which account you're currently acting as — authuser 0 (your primary Google account) or brand abcdef… if you've picked a brand account via YouTube's avatar menu. Switch the YouTube avatar and reload before running bulk operations if the indicator isn't what you expect.
Each video row gets a checkbox. Click to toggle. The counter in the panel header tracks your current selection.
Pick one or more destination playlists from the list and click Go. Videos are added to every selected destination. The source playlist is not modified.
Same as Copy, plus removes each video from the current (source) playlist once the copy succeeds. The source must be owned by the currently-active account.
Downloads the current playlist as a ytpm.bundle/1 JSON file. Schema:
{
"schema": "ytpm.bundle/1",
"exportedAt": "2026-04-21T...",
"playlists": [
{
"id": "PL...",
"title": "...",
"itemCount": 42,
"items": [
{ "videoId": "...", "setVideoId": "...", "title": "...",
"channelId": "...", "channelName": "...",
"isPlayable": true, "deleted": false }
]
}
]
}
Reads a ytpm.bundle/1 file and adds its videos to whichever playlist you're currently viewing. Before writing, a confirmation shows:
Add 47 new videos to "My Playlist"?
(12 already in playlist, 3 no longer on YouTube — will be skipped)
Duplicate videos (by videoId) are automatically skipped. To import into a different playlist, open that playlist first and then import.
document.hidden).The script auto-detects which Google account / brand channel is active in the tab and routes all requests accordingly. If you switch accounts via the YouTube avatar menu, YouTube does a full page reload — after that, the panel reflects the new account and operations go there.
Your cookie jar is not required to be for a single account; the script uses whatever YouTube considers active. If you keep ending up acting as the wrong account, confirm the active account in YouTube's avatar menu, then reload.
No P badge appears.
Open DevTools (F12) and look for [YTPM] mounted (v0.1.3) in the console. If it's not there, the script didn't run — check that Tampermonkey is enabled and the script is enabled.
Console shows Failed to set 'innerHTML' on 'ShadowRoot'.
YouTube tightened Trusted Types CSP; file a bug with the exact error — we'll need to rework the rendering path.
No SAPISID cookie — are you signed in?
Sign into YouTube. The script requires an authenticated session.
INNERTUBE_CONTEXT missing.
The page hadn't finished loading when the script booted. Reload.
Copy / Move fails after partial success.
Check the panel's log (shows the last 10 events). Error: Rate-limited after N retries means YouTube is throttling — wait a few minutes. failed=N at the end means the verifier detected N items that were dropped and couldn't be re-applied within 3 retries — re-select those specific items and retry.
Destination picker is showing playlists from the wrong account. Use the YouTube avatar menu to switch to the account you want, let the page reload, then expand the panel again. The panel header should show the new account; if it doesn't, something is wrong with detection (file a bug).
Single file, no build step. Edit PlaylistPlus.user.js directly; Tampermonkey picks up changes on save (you may need to reload the YouTube tab). Sections are labeled with ──── Section Name banner comments — grep to jump around.
Tests live in PlaylistPlus_tests/ (Playwright). Not needed for script installation, useful if you change DOM selectors or InnerTube payloads.
