Titles, descriptions, tags and thumbnails for your videos in YouTube Studio, with upload checks and thumbnail A/B tests. Write better titles, make thumbnails and check every upload, right inside YouTube Studio. playlist.al adds one panel to a video's Details page in YouTube Studio, for creators and channel teams who work with playlist.al. WRITE WITH AI • Titles, descriptions and tags written from your video, shown next to your current text. • Pick a style (direct, story or short), then apply it to the field in one click or copy it. • Nothing is saved until you save in Studio. THUMBNAIL CREATOR • Make thumbnail options from frames of your video and your own pictures, such as a face or a logo. • Custom mode: choose the frames and a style yourself. Magic mode: one click picks the frames, style and text. • Set the one you like as the thumbnail. PUBLISH CHECKLIST • 16 checks in three groups (details, in-video, publishing) show what a video is missing before it goes out: chapters, hashtags, tags, links, pinned comment and more. • Fix any item where it is, or fix them all at once with Fix all. TEST & COMPARE • Start YouTube's own A/B test of titles and thumbnails from the same panel. HOW IT WORKS • Sign in with your playlist.al account. A playlist.al account is required: https://playlist.al • The extension runs only on studio.youtube.com and acts only when you click one of its buttons.
