Rubi – Vocaloid & Vocal Synth Lyrics, Karaoke for YouTube

Vocaloid, UTAU & Synthesizer V lyrics on YouTube: Japanese, romaji, English, synced karaoke-style. Sync any song, share to LRCLIB.

Rubi is made for Vocaloid and vocal synth fans: songs sung by Vocaloid, UTAU, Synthesizer V and CeVIO voices. Open one on YouTube or YouTube Music and Rubi shows its lyrics: the original Japanese, the romaji reading and an English translation, line by line and in time with the music. It's built on VocaDB and the Vocaloid Lyrics Wiki, the community's own databases, so it knows these songs by their videos: original MVs, reuploads and covers (歌ってみた) included. Many other Japanese songs work too, through LRCLIB, a free, open database of time-synced lyrics that anyone can add to and that many music players and apps use. SYNC A SONG YOURSELF, SHARE IT IN ONE CLICK Some songs have lyrics but no timing anywhere. Rubi makes fixing that quick: • Play the video and press S as each line starts. Backspace undoes a line, Enter saves. • Your sync is saved for that video and works straight away. • Press "Share on LRCLIB". Rubi fills in the title, artist, album and length, checks that the video matches the released track, and handles LRCLIB's anti-spam check for you. No account needed. • Everyone who plays that song gets your timing, in Rubi and in every other player that uses LRCLIB. Help the community: every song you sync is one nobody else has to. WHAT ELSE IT DOES • Finds the song by itself, from the video, the original linked in its description, or its title. • Karaoke on the video. The current line sits large in the middle of the player and fills as it's sung, with the next line below. • Or beside the video. A lyrics panel follows the song; click any line to jump to it, or scroll ahead and "Sync to current line" brings you back. • Choose what you read. Show or hide Japanese, romaji and English, in the order you like. • Synced automatically, from the video's captions or LRCLIB. • A colour for every voice. The best-known singers each have their own colour theme, picked automatically from the song's singer. • Works on YouTube Music too, with timed lyrics where YouTube Music shows plain text. • In your language. Menus in English, Japanese, Korean and Chinese (Simplified and Traditional). The translated lyrics are in English. • Stays out of the way. Rubi only appears on songs. Vlogs, games and Shorts are left alone, and one switch turns it off everywhere. WHERE THE LYRICS COME FROM VocaDB, the Vocaloid Lyrics Wiki, LRCLIB and Genius. Rubi doesn't host any lyrics itself. When a song isn't found, "Report a problem" sends the details to the developer in one click. PRIVATE BY DESIGN No account, no ads, no tracking. Your settings and syncs stay in your browser. Only the song's title, artist or video ID is sent to the lyrics sites to look it up. VOCALOID is a registered trademark of Yamaha Corporation. Rubi is an independent project, not affiliated with YouTube or with the lyrics sites it uses.
